    • This invention consists of the production of a salt of acyl phosphate in an aqueous solution by a process which involves (1) acylation of phosphoric acid (H.sub.3 PO.sub.4) with an acid anhydride of the general formula RCOX, where R can be hydrogen or a lower alkyl or aryl group having from 1 to 10 carbon atoms, and X can be a leaving group of the general formula OR, OCOR, X or NR.sub.2, followed by (2a) extraction of acyl phosphate to water by treatment of the reaction mixture with an aqueous bicarbonate or hydroxide solution or other basic aqueous solution, if the reaction is carried out in non-aqueous solvent or (2b) in the case where water has been used as reaction solvent acidification with acid or acid form of a carbon exchange resin. After (3) extraction of residual carboxylic acid from the resulting acidic aqueous mixture using a solvent in which the acid is soluble but with which water does not mix, the remaining aqueous solution of acyl phosphate is (4) neutralized by addition of a base such as sodium or potassium hydroxide.
    • 本发明包括在水溶液中制备酰基磷酸盐的方法,该方法包括:(1)用通式RCOX的酸酐使磷酸(H 3 PO 4)酰化,其中R可以是氢或低级烷基 或具有1至10个碳原子的芳基,X可以是通式OR,OCOR,X或NR2的离去基团,然后(2a)通过用水溶液处理反应混合物(2a)将酰基磷酸酯提取到水中 碳酸氢盐或氢氧化物溶液或其他碱性水溶液,如果反应在非水溶剂中进行,或(2b)在使用水作为与酸或酸形式的碳交换树脂反应溶剂酸化的情况下。 (3)使用其中酸是可溶性但不与水混合的溶剂从所得酸性含水混合物中提取残余羧酸后,残留的酰基磷酸酯水溶液(4)通过加入碱中和 作为氢氧化钠或氢氧化钾。

    • The invention comprises organic phosphorus compounds of the general formula wherein R1 and R2, which may be the same or different represent C1-C4 alkyl, C1-C4 alkoxy, C1-C4 alkylmercapto, C1-C4 alkylamino, di-C1-C4 alkylamine, cyano-substituted di-C1-C4-alkylamino, phenyl, C1-C4 alkylmercapto-substituted phenoxy, phenylamino, or morpholyl radicals or a further group or R2 and R2 together form an alkylene-dioxy group; R3 and R4, which may be the same or different, represent hydrogen atoms or C1-C4 alkyl, cyano-substituted C1-C4 alkyl, or phenyl radicals or the group represents a morpholyl or piperidyl radical; A represents the residue of carbonic, sulphurous, phenyldithiophosphonic, C1-C4 alkoxy-substituted phenyldithiophosphonic, phthalic, halogen-substituted phthalic, or maleic acid; and X represents an electron pair or a sulphur atom. These compounds may be produced by reacting an appropriate organic compound of trivalent phosphorus containing at least one phosphorus-nitrogen band with an appropriate organic or triorganic anhydride to give a compound in which X is an electron pair and, if desired, reacting said compound with elementary sulphur or a sulphur-yielding agent to give a compound in which X is a sulphur atom. The compounds of the invention exhibit pesticidal activity (see Division A5).ALSO:Pesticidal compositions contain an organophosphorus compound of the general formula wherein R1 and R2, which may be the same or different, represent C1-C4 alkyl, C1-C4 alkoxy, C1-C4 alkylmercapto, C1-C4 alkylamino, di-C1-C4-alkylamino, cyano-substituted-di-C1-C4 alkylamino, phenyl, C1-C4 alkylmercapto-substituted phenoxy, phenylamino, or morpholyl radicals or a further group or R1 and R2 together form an alkylenedioxy group; R3 and R4, which may be the same or different, represent hydrogen atoms or C1-C4 alkyl, cyano-substituted C1-C4 alkyl, or phenyl radicals or the group represents a morpholyl or piperidyl radical; A represents the residue of carbonic, sulphurous, phenyldithiophosphoric, C1-C4 alkoxy-substituted phenyldithiophosphoric, phthalic, halogen substituted phthalic or maleic acid; and X represents an eletron pair or a sulphur atom, in admixture with a solid or liquid diluent or carrier.
