Usage

General Description

Tripropan-2-yl phosphorotetrathioate, also known as DEF, is a potent organophosphate insecticide and acaricide. It is primarily used in agricultural in the control of a wide range of pests on a variety of crops. DEF works by inhibiting the activity of acetylcholinesterase, an essential enzyme in the nervous system of insects and mites, leading to paralysis and death. It is highly toxic to humans and other mammals, and exposure can result in severe symptoms such as nausea, vomiting, diarrhea, and respiratory distress. Due to its toxicity and potential for environmental harm, the use of tripropan-2-yl phosphorotetrathioate is heavily regulated in many countries.

Effect of iodine on the reaction of tetraphosphorus decasulfide with dialkyl disulfides

Elemental iodine decreases the temperature of the reaction of P4S10 with disulfides, which results in the formation of trialkyl tetrathiolothionophosphates, from 100-110°C to 20-60°C. The latter decompose to trialkyl tetrathiophosphates.
