Mechanism of Proton Removal from 2-Phenylazoresorcinol Monoanion by Hydroxide Ion in 95percent (v/v) Dimethyl Sulphoxide-Water

Dissociation of the hydrogen-bonded proton from 2-phenylazoresorcinol monoanion requires high concentrations of sodium hydroxide in aqueous solution but occurs at low hydroxide ion concentrations in 95percent (v/v) Me2SO-H2O.Kinetic studies in 95percent (v/v) Me2SO-H2O show that proton removal takes place by single-step attack of hydroxide ion on the hydrogen-bonded proton and by a two-step process through a non-hydrogen-bonded open form, with half-lives for the reaction in the range 8-20 μs.

Insecticide evaporator comprising a stabilizer

Insecticide evaporator comprising at least one volatile phosphoric ester insecticide, an agent for stabilizing the said ester against decomposition by protonization and used in an amount of 0.2 to 20% based on the weight of phosphoric ester, characterized in that the stabilizing agent contains at least one compound selected from the compounds of the chemical class of 1,3-benzodioxoles and at least one diazene.
