Abstract
The invention relates to the technical field of packing preparation, in particular to a method for co-production of carbon dioxide in the preparation of nano barium sulfate by barium carbonate. In the main technical scheme, barium carbonate and sulfuric acid react to obtain barium sulfate and carbon dioxide, and the barium sulfate is dried and crushed to obtain the precipitated barium sulfate. The invention has the advantages of simple production process and equipment and high yield, and overcomes the defects of the conventional method such as large material transportation volume, low efficiency and huge process equipment. Moreover, since the low-grade barium carbonate is used for producing the high-grade barium sulfate, the cost is low. Particularly, the invention not only can be used for preparing the target product precipitated barium sulfate, but also can be used for co-production of the carbon dioxide, thereby creating high economic value.
Description
Technical field
The present invention relates to technical field of filler preparation, especially a kind of method for preparing the process white co-producing carbon dioxide with barium carbonate.
Background technology
Barite belongs to Nonrenewable resources, is one of trump-cards in the export of mineral products of China, is widely used in the weighting agent of oil, Sweet natural gas drilling mud, and the consumption in fields such as barium chemical industry, fillers is also increasing year by year.China's barite resource is quite abundant, is distributed in the whole nation 21 provinces (district), and 3.6 hundred million tons in total retained reserve ore occupies the 1st in the world.Wherein, barium sulfate is because water insoluble, is insoluble to acid and has following purposes widely:
Raw material or weighting agent as paint, printing ink, plastics, poster paint, makeup, store battery, both make weighting agent in the rubber item, played strengthening action again, made weighting agent and weighting agent in the polychlorostyrene ethane resin, the surface coated agent of photographic pape and art paper, the sizing agent that textile industry is used.Glasswork can play froth breaking and increase the glossy effect as finings.Can be used as the protection walls material that anti-radioactive rays are used.Also be used for industries such as pottery, enamel, spices and pigment.Also be the raw material material of making other barium salts---powder coating, paint, priming paint peculiar to vessel, armament equipment lacquer, automobile finish, emulsion paint, interior outer wall building coating, can improve that product is fast light, weather-proof, chemically-resistant and electrochemical corrosion and product decoration effect, strengthen the resistance to impact shock of coating.Inorganic industry is as the raw material of making other barium salts such as hydrated barta, barium carbonate, barium carbonate etc.Be used for bottoming and modulation printing paint vehicle during timber industry production grain printing plate.In the organic synthesis as phthalocyanine and color lake production physique filler.
The preparation method of tradition barium sulfate is: is mixed with the saltcake solution that adds after removing calcium, magnesium by barium sulfide solution, react in 80 ℃, generate and precipitate, after suction filtration, washing and pickling, adjusting pH value 5～6 refilters, drying, and pulverizing makes.
For example application number is 200810048340.6 to disclose a kind of preparation method of process white, is to filter and obtain purified solution, recombination separation, acid adjustment, drying, evaporation adding the nano level filter cloth among traditional preparation method; Application number is that 200510057117.4 preparation methods that also disclose a kind of process white are with witherite and sour hybrid reaction, adds alkali in the gained solution, after filtering separation is removed insoluble impurities, obtains containing Ba
2+, Ca
2+Solution, according to Ba in the solution
2+Content adds sulfuric acid, makes Ba in the solution
2+Just all separate out, filtering separation gets process white, and filtered liquid is added sulfuric acid again, makes Ca in the solution
2+All separate out.But prior art all also exists production process equipment bulky complex, the higher drawback of cost, and barium slag also of no use at present prepares the relevant report of the method for process white co-production of hydrochloric.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the object of the present invention is to provide the method for a kind of production technique process white co-producing carbon dioxide simple, with low cost.
To achieve these goals, technical scheme of the present invention is as follows:
A kind ofly prepare the method for process white co-producing carbon dioxide with barium carbonate, preparation technology is:
Earlier that barium carbonate is water-soluble, handle the back with 1%～3% tensio-active agent and be injected in the reactor to stockline by barium carbonate; To dissolve good sulfuric acid again and give the stockline injecting reactor by sulfuric acid, barium carbonate and sulfuric acid are 1: 0.2～0.7 to mix by the mass ratio of pure substance in the described reactor; Evenly stir with 60～500 rev/mins rotating speed then, reaction 4～8 as a child obtained mix products; Filter through whizzer after the mix products removal of impurities, filter cake carries out drying and pulverizing by drying machine, pulverizer drying successively after washing, be packaged to be the process white product; The gas that produces in the reaction process is carbon dioxide product through the can of overdraft steel cylinder.
Described tensio-active agent is the one or more combination thing in the cruel coupling agent of phthalandione, stearic acid or the xylogen.
Chemical principle of the present invention is as follows:
BaCO
3+H
2SO
4＝BaSO
4+CO
2+H
2O
The present invention utilizes barium carbonate and sulfuric acid reaction to obtain barium sulfate and carbonic acid gas earlier, barium sulfate makes process white through super-dry, pulverizing, production technique of the present invention and equipment are simple, productive rate is big, overcome the defective that the material traffic capacity is big in the traditional method, efficient is low, processing unit is huge, and with the rudimentary high-grade barium sulfate of barium carbonate production, with low cost; Especially prepare the target product process white, simultaneously can also the co-producing carbon dioxide product, create very high economic worth.
