Dangerous Chemical Phosphorus Sulfide

Phosphorus Pentasulfide is an inorganic compound with the chemical formula P2S5. Phosphorus Pentasulfide Cas 1314-80-3 is a yellow solid and is stable when dry. However, it hydrolyzes into phosphoric acid and hydrogen sulfide when exposed to water, so it smells like rotten eggs in the air.

Phosphorus Pentasulfide Hazardous Chemical (commonly known as tetraphosphorus decasulfide-P4S10 internationally) is a widely used basic chemical raw material and can be widely used in organophosphorus pesticides. Phosphorus pentasulfide reacts with alcohol to obtain an important phosphorus-containing intermediate "sulfide", which can then be used to synthesize a variety of phosphorodithioate pesticides.

Organophosphorus pesticides refer to organic compound pesticides containing phosphorus. Mainly used to prevent and control plant diseases, insects and weeds. It is mostly an oily liquid with a garlic smell, highly volatile, slightly soluble in water, and destroyed by alkali. In practical applications, high-efficiency, low-toxicity and low-residue varieties should be selected, such as trichlorfon, dimethoate, omethoate, ethyl 1605, phoxim, synergistic phosphorus and many other varieties.
