China's iron oxide yellow is largely that wet method is produced using wet method air oxidation process.Wherein wet processing includes two kinds of acid system and alkaline process.Acid system is also known as crystal seed method, is subdivided into two kinds of techniques of iron sheet method and dripping method, and acid system prepares iron oxide yellow and mainly divides two steps to carry out:
(1) FeSO is used4·7H2O, NaOH or NH3·H2O, air oxidation prepare crystal seed;
(2) with crystal seed, FeS04, iron sheet, air carry out second oxidation output iron oxide yellow.
Herein, NaOH or NH3·H2O is used as precipitating reagent, with FeSO4Reaction generation ferrous hydroxide precipitation;Air is used as oxidant;Iron sheet is and FeSO4Sulfuric acid reaction produced by oxidizing process maintains the pH value of solution there is provided the ferrous ion needed for reaction system.
Course of reaction is:
4FeSO4+O2+6H2O → 4FeOOH (iron oxide yellow)+4H2SO4
4H2SO4+4Fe→4FeSO4+4H2
If replacing iron sheet, and the acid for being added dropwise in ammoniacal liquor or sodium hydroxide and being produced in oxidizing process by the way that copperas solution is added dropwise in second oxidation, then this method is referred to as dripping method.
Course of reaction is:
4FeSO4+O2+ 8NaOH → 4FeOOH (iron oxide yellow)+2H2O+4Na2SO4
2) oxidizing process production iron oxide yellow
Make oxidant using sodium chlorate etc., concentration, reaction temperature, time and the pH value of certain ferrous sulfate are controlled, by Fe2+It is oxidized to Fe3+It is eventually converted into iron oxide yellow.
3) aniline process
In aniline process production process iron oxide yellow is generated with iron reduction nitrobenzene.
Current ferric oxide yellow pigment is produced using crystal seed method mostly:
1) reacted first by ferrous sulfate and alkali, in certain alkali than R values (R=2OH-/Fe2+) under generate ferrous hydroxide colloid, be subsequently passed air oxidation, by ferrous hydroxide colloidal silica be iron oxide yellow crystal seed.
2) on the basis of iron oxide yellow crystal seed, it is continuously replenished ferrous sulfate (dripping method) or iron sheet (iron sheet method) and is passed through air, control ph within the specific limits, makes iron oxide yellow crystal seed constantly grow up, and finally gives qualified iron oxide yellow.
During ferrous sulfate is used for the dripping method production iron oxide yellow of raw material, ferrous sulfate needs refined in advance, removing impurity therein first, in order to avoid the quality of these impurity effect iron oxide yellows.Crystal seed second oxidation process needs to consume the acid produced in the higher ammoniacal liquor of value or sodium hydroxide and in oxidizing process afterwards, the relatively low sodium sulphate of value or ammonium sulfate waste water are produced, wherein the mol ratio of the alkali (ammoniacal liquor or sodium hydroxide) consumed and ferrous sulfate is 2:1.Ferrous sulfate can produce sulfuric acid during iron oxide yellow is oxidized to, lack buffer substance in solution, to maintain the stabilization of solution ph (between pH value about 2.5-4.0), therefore need to be continuously replenished alkali maintenance solution ph during second oxidation, wherein product iron oxide yellow is solid, it must be soluble sulphate that alkali and sulfuric acid, which neutralize and obtains sulfate, therefore integrated cost considers, sodium hydroxide or ammoniacal liquor can only be used to be used as the alkali of neutralisation of sulphuric acid.
During iron sheet is used for the iron sheet method production iron oxide yellow of raw material, iron sheet is converted into iron oxide yellow as raw material, period such as does not filter at the dedoping step, the impurity of iron sheet can be transferred completely into iron oxide yellow product, therefore the higher iron sheet of quality is needed, it is general to use low-carbon iron sheet, to ensure the quality of iron oxide yellow product.
During the second oxidation that crystal seed method produces iron oxide yellow, solution presents acid, ferrous ion is weaker compared to alkaline environment reproducibility in sour environment, therefore the time needed for ferrous ion oxidation by air is longer, and the synthesis of iron oxide yellow can just be completed by generally requiring 30-60 hours.
Oxidizing process production iron oxide yellow needs to consume substantial amounts of oxidant, such as sodium chlorate, significantly higher compared to the crystal seed method production cost for using air as oxidant.
Therefore, in the production process of existing iron oxide yellow, to ensure the quality of iron oxide yellow, raw material sulphuric acid ferrous iron, which needs to refine in advance, removes impurity or from the less low-carbon iron sheet of impurity as raw material, limits the raw material sources of iron oxide yellow.And using ferrous sulfate in the dripping method of raw material, it is necessary to use ammoniacal liquor or sodium hydroxide as the acid produced in alkali with second oxidation process.Finally because ferrous ions are slower, the production cycle of iron oxide yellow is very long, it is necessary to which 30-60 hours can just complete.

After the above method, it uses complexing agent as solvent, ferrous ion is dissolved in weakly alkaline solution, reoxidize as iron oxide pigment, and cheap calcium oxide is used as alkali, neutralisation of sulphuric acid ferrous iron is converted into the acid produced during iron oxide yellow, using ferrous ion it is more oxidizable in alkaline environment the characteristics of, significantly shorten iron oxide yellow the oxidation production cycle.
Wherein, the present invention will be described in conjunction with the embodiments.
Wherein, in embodiment, complexing agent is ammonia carboxylation compound or organic amine compound (being illustrated below by taking complexones as an example), there is stronger complexing power to ferrous ion, the ferrous compound of solubility is formed with ferrous ion, ferrous ion is not produced precipitation between pH value 7.0-13.0, exist in the form of soluble ferrous complex.Ferrous sulfate and complexones formation ferrous complex and sulfate radical, hydrogen ion or oxidizing or by catalyst (such as relatively low metallic compound of mantoquita, nickel salt, platinum salt, gold salt, silver salt, cobalt salt hydrogen overvoltage by other in metallic iron displacement complexones, by replacing in iron surface formation metal level, accelerate the dissolving of metallic iron using galvanic effect) catalysis, obtain ferrous complex.Now, in alkaline solution, the major impurity in ferrous sulfate, metallic iron, including carbon, silicon, magnesium, titanium etc., exist in solid chemical compound form, clean iron-containing liquor can obtain by the separation of a simple step.Current iron oxide yellow production technology, lacks the dedoping step of raw material, need to be refined in advance when the use of ferrous sulfate being raw material, to separate wherein impurity, the higher low-carbon iron sheet of quality need to be used as raw material when the use of metallic iron being raw material, to ensure the quality of iron oxide yellow.
After iron-containing liquor purification, air is passed through thereto, oxygen therein can aoxidize ferrous complex, control oxidizing temperature, oxidization time, oxidation rate can respectively obtain the products such as iron oxide yellow, iron oxide red, iron oxide black.Ferrous iron can produce hydrogen ion during iron oxide pigment is oxidized to and be neutralized, it is necessary to add alkali, maintain the stabilization of solution ph.The complexing agent complexones that the present invention is used is weak acid, organic amine is weak base, complexones is cushioning liquid with its conjugate base composition solution, organic amine compound and its conjugate acid composition solution, and there is stronger buffer capacity between pH value 7.0-13.0, hydrogen ion can be absorbed and the pH value of solution is changed little.Ferrous iron can produce hydrogen ion in oxidizing process, and hydrogen ion can be absorbed by the Conjugate Acid-Base Pairs in cushioning liquid, maintain solution ph stable.Therefore, extra alkali or iron sheet control ph need not be added during ferrous oxidation, the stabilization of solution ph can be maintained using the buffer capacity of reaction solution.
During iron-containing liquor is aoxidized, in order to obtain, form and aspect are pure, the suitable iron oxide pigment of particle size is, it is necessary to control the oxidation rate of ferrous iron.In the present invention, ferrous oxidation speed is together decided on by throughput, oxygen concentration, ferrous iron concentration, therefore the oxidation rate of ferrous iron can be directly controlled by way of changing throughput, gas oxygen content;On the other hand, the mode that ferrous iron concentration in solution can be changed controls oxidation rate, in order to reduce operating process, the iron-containing liquor containing higher concentration ferrous ion can be pre-configured with, using step 2) in oxidation terminate after reaction mother liquor be used as bottom liquid, oxygen-containing gas is passed through thereto, iron-containing liquor is added using the mode for being added dropwise or being added portionwise, by way of controlling iron-containing liquor and adding speed, control the ferrous iron concentration in oxidizing process solution, and then ferrous oxidation rate is controlled, obtain that form and aspect are pure, the suitable iron oxide pigment of particle size.
Further, can also be to step 2) in into solution add no more than 100g/L crystal seed or other can produce the material of nucleus, the crystal seed is the iron oxide yellow or iron oxide red or iron oxide black crystal seed synthesized using disclosed method, and other described materials that can produce nucleus are can be with the one or more in the copper of ferric ion formation precipitation, zinc, lead, cadmium, nickel, cobalt, aluminium, barium compound.
Iron oxide yellow, iron oxide red, the nucleating condition of iron oxide black are closer to, and also have certain difference, such as when ferrous iron concentration is higher, can preferentially obtain iron oxide black product, when temperature is higher, throughput is larger, preferentially obtain iron oxide red product.Weakly alkaline solution used in the present invention is different from the acid solution and strong alkali solution of current commercial Application, by strict temperature control, time, oxidation rate, ferrous iron concentration, even if without iron oxide yellow, iron oxide red or iron oxide black product can also be directly obtained under conditions of crystal seed.In the present invention, ferrous oxidation by air first is ferric hydroxide colloid, and ferric hydroxide colloid obtains iron oxide pigment by polymerization, recrystallization again.In general, the polymerization of colloid, recrystallization can by thermal polymerization, saltout and add extra crystal seed and realize, in the present invention, by way of being combined heating, saltouing or both, iron oxide pigment, specifically, step 2 are obtained under conditions of without crystal seed) in a scheme being more highly preferred to be 50-110 DEG C of reaction temperature, inertia salinity 1.0-3.5mol/L, by ferrous ions and can be eventually converted into iron oxide yellow or oxidationization iron oxide red or iron oxide black.Ferric hydroxide colloid can also be converted into corresponding iron oxide pigment by the present invention by mode associated with individually adding crystal seed or addition crystal seed and thermal polymerization, saltouing.In general, crystal seed is divided into two kinds, it is a kind of be particle it is smaller, can be with the crystal of continued growth, such as iron oxide yellow, iron oxide red, iron oxide black crystal seed, these crystal seeds can use existing industry application method thereof or other disclosed technical data synthesis;It is another to be and iron oxide yellow, iron oxide red, iron oxide black has other materials of similar crystal structure, because crystal structure is similar, ferric hydroxide colloid can adsorb on these materials and be converted into iron oxide yellow or iron oxide red or iron oxide black, finally give iron oxide pigment product, these materials include zinc ferrite, barium ferrite, cobalt ferrite, nickel ferrite based magnetic loaded, ferrous acid cadmium, ferrous acid lead, coppe ferrite, aluminum oxyhydroxide, aluminium hydroxide, aluminum oxide etc., therefore copper can be added, zinc, lead, cadmium, nickel, cobalt, aluminium, barium compound, corresponding ferrite or other compounds are obtained in the solution as crystal seed, ferric hydroxide colloid is set to be eventually converted into iron oxide pigment, specifically, step 2) in a scheme being more highly preferred to be 40-90 DEG C of reaction temperature, inertia salinity 0.5-1.5mol/L, add the iron oxide yellow crystal seed of existing iron oxide yellow commercial synthesis, by ferrous ions and qualified ferric oxide yellow pigment can be eventually converted into.
In general, colloid can be stabilized under lower temperature and relatively low salinity, therefore in the scheme that the application is proposed, ferric iron compound can also be used as raw material, specifically, under conditions of control temperature and inertia salinity, ferric iron compound reacts with reaction solution first, obtain ferric hydroxide colloid, ferric hydroxide colloid particle diameter is smaller, can obtain clean ferric hydroxide colloid solution (iron-containing liquor) by filtering, then by means such as heating, addition crystal seeds, ferric hydroxide colloid is set to be converted into iron oxide pigment.The source of ferrous sulfate is than wide; a certain amount of ferric iron would generally be contained and ferrous sulfate is easily oxidized, therefore in ferrous sulfate, in the method as proposed in the present invention; ferric iron in ferrous sulfate does not constitute influence to whole technique, has widened the ferrous applicability of raw material sulphuric acid.Simultaneously, comprise only ferric compound, such as ferric sulfate, raw material is can act also as in the present invention to use, difference is that ferric sulfate has been ferric form, oxygen need not be passed through again to be aoxidized, by thermal polymerization, saltout and add extra crystal seed and ferric sulfate can be converted into iron oxide pigment.
In addition, during air oxidation, ferrous iron concentration, oxidation rate can be controlled, and then the granular size of iron oxide pigment is controlled, various sizes of iron oxide pigment is obtained, in order to prevent the reunion of iron oxide pigment, surfactant can be added, including anionic surfactant, cationic surface active agent, zwitterionic surfactant, nonionic surface active agent, the reunion between iron oxides pigment particles is prevented, the iron oxide pigment of polymolecularity is obtained.These surfactants include stearic acid, oleic acid, laurate, quaternary ammonium salt, cocounut oil phthalein amine CAB, dodecyl alanine, isomery alcohol polyoxyethylene poly-oxygen propylene aether, polyethylene adjoins pyrrolidone, OPEO, Triton X-100, polyoxyethylene sorbitan fatty acid ester, dodecyl sodium sulfate, lauryl sodium sulfate, in APES and other organic or inorganics that can produce absorption on iron oxide pigment surface have the material of surface-active action.
In addition, during ferrous oxidation, hydrogen ion can be produced, in the present invention, these hydrogen ions are received by the reaction solution with buffer capacity containing complexing agent Conjugate Acid-Base Pairs, keep reacting liquid pH value to stablize relatively, in order to recycle reaction solution, the regeneration of reaction solution need to just can be achieved with alkaline matter and/or being replaced into hydrogen in the hydrogen ion of absorption, and recycles.When specifically, using metallic iron as raw material, iron can replace the hydrogen ion in reaction solution, produce hydrogen, i.e., the hydrogen ion produced ferrous ions process is converted into the acidity in hydrogen discharge, elimination reaction solution.During for using ferrous sulfate as raw material, on the one hand, the hydrogen ion that ferrous ions process is produced is enriched with the solution, another aspect sulfate radical can be also enriched with the solution, therefore need to remove hydrogen ion unnecessary in solution and sulfate ion, in the technical scheme that the application is proposed, sulfate radical exists in the form of Soluble Anions, calcium can be used, the oxide or hydroxide of barium, on the one hand unnecessary sulfate radical is converted into insoluble calcium sulfate or barium sulfate precipitate, another aspect calcium oxide or barium monoxide are used as basic anhydride, can be with the hydrogen ion in neutralization reaction liquid, realize the recycling of reaction solution.And calcium oxide is worth the ammoniacal liquor and sodium hydroxide well below current iron oxide yellow industrial application, can greatly reduce the production cost of iron oxide yellow as cheap alkali.
