A method for the synthesis of esters of sulfur

The invention discloses a synthetic method for thiophosphate. The synthetic method comprises the following steps: after taking thiophosphate aqueous liquor and methyl chloroacetate as raw materials to carry out primary reaction on thiophosphate and methyl chloroacetate, separating to obtain an oil phase and a water phase, carrying out continuous cyclic synthesis by virtue of the following two-step reaction: a first step, namely adding methyl chloroacetate into a water phase, reacting, and after reacting, separating to obtain oil phase of thiophosphate-containing methyl chloroacetate and water phase capable of being subjected to posttreatment and exhausted, and a second step, namely adding thiophosphate aqueous liquor into the oil phase of thiophosphate-containing methyl chloroacetate to react, and after the reacting, separating to obtain the oil phase containing thiophosphate and excessive methyl chloroacetate and the water phase, wherein methyl chloroacetate is separated from the oil phase containing thiophosphate and excessive methyl chloroacetate by virtue of distillation to obtain the thiophosphate, and circulating the water phase to the first step. The synthetic method is high in yield, short in synthesis time and low in cost, capable of effectively utilizing various raw materials and products and lowering the content of the thiophosphate in wastewater, and environmentally friendly.
