A phosphonium salt compound having an acryl group which is represented by the following general formula (3) can be made in simple operations: ##STR1## (wherein A represents a alkylene group, Y represents Cl, Br or I, R.sup.1 represents H or CH.sub.3, and R.sup.2, R.sup.3 and R.sup.4 represent a alkyl group having 1-8 carbon atoms, cycloalkyl, aryl, alkaryl or aralkyl group) by reacting an unsaturated aliphatic carboxylic acid halide of the following general formula (1): CH.sub.2 .dbd.CR.sup.1 --COX (1) (wherein R.sup.1 represents H or CH.sub.3 and X represents Cl, Br or I) with a hydroxyalkyl phosphonium salt compound of the following general formula (2): [HO--A--P.sup.+ R.sup.2 R.sup.3 R.sup.4 ]Y.sup.- (2) (wherein A, Y, R.sup.2, R.sup.3 and R.sup.4 have the same meanings as defined above). The present invention is industrially advantageous since the product can have a very high purity and be obtained in high yield by an easy operation.
可以通过简单的操作制备具有丙烯酰基的膦盐化合物,其由以下通式(3)表示:
##STR1##
其中,A代表烷基,Y代表Cl,Br或I,R1代表H或CH3,R2,R3和R4代表具有1-8个碳原子的烷基,环烷基,芳基,烷芳基或芳烷基。方法是将以下通式(1)的不饱和脂肪族羧酸卤化物与以下通式(2)的羟基烷基膦盐化合物反应:
CH2.dbd.CR1--COX(1)(其中,R1代表H或CH3,X代表Cl,Br或I)
[HO--A--P+R2R3R4]Y-(2)(其中,A,Y,R2,R3和R4的定义与上述相同)
该发明具有工业优点,因为通过简单的操作可以获得非常高纯度和高产率的产品。
