This is a key intermediate for the preparation of sulfur (alcohol) phosphate insecticides, with the following structural formula:
The most commonly used method in industry is made by adding sulfur to salt with dialkyl phosphite.
In the above reaction, Na2CO3, (NH4)2CO3, etc. can also be used instead of ammonia. This reaction is carried out at normal temperature and pressure with high yield. In addition, sulfur (alcohol) phosphate can also be obtained by alkaline hydrolysis of thiophosphoryl chloride or reaction of phosphoryl chloride with potassium sulfide.
