Description
The right of priority that present patent application requires is that on October 25th, 2004 submitted to, application number is 60/621,972 temporary patent application.
Technical field
The present invention relates in general to the method for a kind of improved economization production dialkylphosphinic acids (dialkylphosphinic acid) compound (being preferably the dialkylphosphinic acids compound of branching).This method can be implemented single phase separation, thereby obtains the highly purified, dialkyl phosphinic acids product.
Background technology
The known multiple derivative that has organic phosphonous acid (phosphinic Acid), these derivatives have sizable commercial value, and have multiple useful application.For example, organic phosphinate (or ester) (phosphinate) and acid be: effectively wetting agent and washing composition; The softening agent of multiple plastics and resin; The tamanori of pitch and similar mixtures thereof; The laking agent of grease and lubricating oil and oxidation retarder (United States Patent (USP) 3,001,938); Inhibiter; Flame-proofness; Flotation aid; The metal extraction agent; Calcium sulphate retarder; And the textile auxiliary agent such as fiber stabilizer (United States Patent (USP) 3,374,288).
It is very important and in demand precursor, intermediate product and final product that highly purified highly branched dialkylphosphinic acids is known as in many special-purpose fields especially.For example, the dialkylphosphinic acids of branching has been served as: complex compound forms agent; The medical active material particularly is suitable for treating the degeneration (for example rheumatoid arthritis) in inflammation and joint those (United States Patent (USP) 4,524,211); General agricultural and household chemical product comprise plant-growth regulator, sterilant, weedicide; And static inhibitor.Even if be not in all these are used, at least also be in multiple these are used, because the thermolability of the reactivity of the phosphorus-hydrogen partial in the monoalkylphosphinic acid by-product and this compounds makes that the existence of monoalkylphosphinic acid by-product is deleterious.
Because above listed multiple feasible practical application, thus to the synthetic needs that produced of simple industrial of the dialkylphosphinic acids of producing these highly purified states.Because aforesaid huge commercial value makes people develop the several different methods of organic phosphonous acid of preparation and phosphinate (or ester) thereof.Although the difference of independent step is all very big in these methods, considerable method all uses the reaction of phosphorus-halogen compounds to obtain C.Can be by making the reaction of haloalkane and phosphuret-(t)ed hydrogen although be well known that all the time, or use Ge Shi (Grignard) reagent to form this key, these methods are for being unpractical with commercial-scale operation.
People such as Stiles have disclosed a kind of utilization and have contained the compound of olefinic double bonds and a class is preferably produced phosphinate (or ester) by the reaction between the compound shown in the formula (I) method (United States Patent (USP) 2,724,718), and formula (I) is:
Wherein Z represents the monovalence alkyl of not fatty family Multiple Bonds, or represents the univalent inorganic cation;
Y represent hydrogen atom, not fatty family Multiple Bonds the monovalence alkyl or-the OZ group, wherein Z is defined as above.The hydrocarbyl carbonate of Hypophosporous Acid, 50 (hypophosphorous acid) salt, the hydrocarbyl carbonate of Hypophosporous Acid, 50, organic phosphonous acid and the list of phosphorous acid (phosphorous acid) or dialkyl ester are all within the scope as the Phosphorus and phosphorus compound of reactant that people such as Stiles propose.A particularly preferred subclass comprises an alkali metal salt of Hypophosporous Acid, 50, sodium hypophosphite for example, people such as Stiles find to make this material and contain at the most the alkene direct addition of 14 carbon atoms and " but produce water soluble detergent with basal ration ground in the operation steps in a single step.”
People such as Stiles are also noted that 1-alkene demonstrates higher slightly speed of reaction than other alkene in these methods.The described addition reaction of people such as Stiles is by causing in the presence of the free radical that contacts closely with reactant.According to people's such as Stiles instruction, temperature of reaction and reaction pressure are all inessential.
People such as Stiles instruction, need be with mole: the calculating of mole be carried out under the situation of addition, preferably makes reactant for waiting mol ratio approximately or making phosphorus compound excessive usually; (for example) institute's bonded olefin(e) compound in the product is exceeded under one mole the situation, preferably making the excessive olefin compound and the ratio of phosphorus compound is 1 mole of about 2 to 3 mol ratio.
A.J.Robertson (United States Patent (USP) 4,374,780) alkene that has disclosed by two moles (is specially 2,4,4 '-2,4,4-Trimethyl-1-pentene-1), with two moles hydrogen peroxide the reaction product of phosphuret-(t)ed hydrogen is oxidized to phosphonous acid subsequently with phosphine gas generation free radical addition, produce highly branched dialkylphosphinic acids, promptly two-2,4,4 '-tri-methyl-amyl phosphonous acid.Yet, must realize phosphuret-(t)ed hydrogen and alkene at high proportion with high phosphuret-(t)ed hydrogen pressure (promptly up to about 1000psig) according to disclosing, and thereby reduce unnecessary three-2,4,4 '-tri-methyl-amyl phosphonous acid by product is because the formation of any this by product all is that overall yield is suffered a loss.In addition, it is believed that temperature is extremely important for the exothermic oxidation stage, because if temperature surpasses about 120 ℃, extra monoalkyl-phosphinous acid is just sloughed and formed to alkyl group; If temperature is lower than about 50 ℃, will cause the reaction times long.It is said the dialkylphosphinic acids productive rate that simple distillation can realize.
Certainly, monoalkyl and dialkylphosphinic acids can also be by using the hydrolysis required at least one quantitative water of stoichiometry under about 160 ℃ to 300 ℃ temperature, make its separately the alkyl ester hydrolytic scission and form, the phosphorus-to-carbon bonds of wherein said alkyl ester at first forms by alternate manner.The alkanol that forms one of hydrolysate is removed (United States Patent (USP) 4,069,247) by distillation usually from reaction mixture.
Phostonic acid also is used to extracting rare-earth element (United States Patent (USP) 5,639,433).Be used for from the conventional process of rare earth element solution (the particularly acidic solution of rare earth element) separation of rare earth elements, material solution is usually to the ore that contains rare earth element (monazite for example, hamartite, xenotime, bauxite and similar raw ore) treating processes.The extract that will contain the rare earth element after the extraction is usually sent into the washer dilute acid wash, then the rare earth element that obtains is sent into securing device (stopper) so that carry out stripping with denseer acid, with separation of rare earth elements.In the prior art, hydrochloric acid is the preferred acid of washing and stripping extract.It is said that two-(2,4, the 4-tri-methyl-amyl) phosphonous acid are preferred extraction agents, are preferred for separation of cobalt from nickel especially.
In addition, end-use about dialkylphosphinic acids and ester thereof, United States Patent (USP) 6,165,427 have disclosed and have used the mixture precipitation and reclaim soluble heavy metal, for example lead, cadmium, zinc class and their mixture from waste water stream that contains two-(n-octyl) phosphonous acid sodium and two-(dodecyl) phosphonous acid sodium.According to instruction, advantageously, make its dissolving by handling throw out with dense hydroxide aqueous solution, in (for example) separatory funnel, contact resulting solution then organophosphorated salt is regenerated from throw out with diethyl ether.Stir and being separated subsequently after, present two-phase.One is the concentration of metal water higher than feedstock solution that it comprised mutually.Another is the ethereal solution of precipitation agent mutually.After the ether evaporation, dialkylphosphinic acids sodium is regenerated.
Usually by adding the organic materials (United States Patent (USP) 4,434,108) such as Di Iso Propyl Ether or sherwood oil, the purifying of evaporate repeatedly subsequently, phostonic acid and its ester being finished in crystallization and filtration (United States Patent (USP) 4,524,211).
Inherent subject matter is extremely difficult dialkylphosphinic acids to be separated with the monoalkyl reaction product that forms together in the aforementioned art methods, and this is because they have very close water-soluble.By being applicable to that practical reaction method production of high purity in the next life dialkylphosphinic acids of producing the compound with multiple structure (particularly highly branched dialkyl group structure) is art-recognized problem, this problem is not resolved so far yet.
Therefore, the objective of the invention is by providing some conditions that a kind of practical and effective treatment process that solves this technical problem is provided, wherein by the condition that is provided in the simple free radical reaction of alpha-olefin one Hypophosporous Acid, 50 or its salt, by simple neutralization/be separated, from dialkylphosphinic acid product, remove any monoalkyl-phosphinous acid and other water-soluble impurity of existence, and need not organic solvent additive as the 3rd component.
