DIPHENYLDITHIOPHOSPHONIC ACID - Introduction
Diphenyl sulfur hydrogen sulfide phosphorus, chemical formula Ph2PSH, is a kind of organic phosphorus sulfur compounds. The following is an introduction to the nature, use, preparation and safety information of diphenyl sulfur hydrogen sulfide:
Nature:
-Appearance is colorless crystals or white solid, soluble in organic solvents such as ethanol, ether and chlorinated hydrocarbons.
-can be slowly oxidized in the air.
-Decomposition may occur at high temperatures and produce toxic gases.
-Decomposes in water to produce sulfurous acid and phosphoric acid.
Use:
-as organic phosphorus chemical raw materials, can be used for the synthesis of other organic phosphorus compounds.
-Used as a reagent, often used in phosphating reactions and reduction reactions in organic synthesis.
Preparation Method:
-A method for synthesizing diphenyl hydrogen sulfide is by reacting triphenyl phosphine and hydrogen sulfide. The target product can be obtained by distillation of the reaction product under reduced pressure.
Safety Information:
-diphenyl sulfur phosphorus hydrosulfide is a toxic compound and should be used with caution.
-Avoid contact with skin and eyes during operation, and wear protective gloves and goggles if necessary.
-Avoid inhaling gas and dust, and maintain good ventilation during operation.
-Store it in a dry, well-ventilated place.
-Waste should be disposed of in accordance with local regulations.
