英国专利902,750号发表了一种具有[(Ry)_2PS.S.C_nH_(2n))_2O结构的含磷化合物,其中R是含6个至18个碳的烷基或环烷基(己基、2-乙基己基、十二烷基、十八烷酰或环己基),Y是氧或硫,也可以两种都存在于同一化合物中,n等于或大于1。它可用一种ω-二卤代烷基醚,XC_nH_(2n)·O·C_nH_(2n)X(其中X是卤素)与具有MS·(YR)_2结构的盐类(其中M是一种碱金属),在有机溶剂(沸点小于100°)存在下,于50～100°时缩合而成。)MS·PS(YR)_2可用化合物RYH与硫化磷或卤硫化磷,在80～120°反应,然后用碱金属的强碱性化合物将上面所制得的酸中和而成。
British Patent No. 902,750 discloses a phosphorus-containing compound having the structure of [(Ry) _2PS.S.C_nH_ (2n)) _2O wherein R is an alkyl or cycloalkyl group having 6 to 18 carbons (hexyl, 2 Ethylhexyl, dodecyl, stearyl or cyclohexyl), Y is oxygen or sulfur, or both may be present in the same compound, and n is equal to or greater than one. It can be prepared with an ω-dihaloalkylether, XC_nH_ (2n) · O · C_nH_ (2n) X (wherein X is a halogen) and a salt having the structure MS · (YR) _2 wherein M is an alkali metal, , In the presence of organic solvents (boiling point less than 100 °) at 50 ~ 100 ° condensation. ) MS · PS (YR) 2 The compound RYH can be reacted with phosphorous sulfide or phosphorus oxybromide at 80-120 ° C and then neutralized with an alkali metal strong base compound.
