Benzenesulfonyl hydrazide Chemical Properties,Uses,Production
Chemical Properties
Benzenesulfonohydrazides,unlike the benzenesulfonamides, are thermally unstable. They decompose, when heated in water in some cases, to form sulfides, thiosulfonates, and nitrogen; for this reason they are used as blowing agents in the production of foams.
Chemical Properties
Benzenesulfonyl hydrazide is WHITE POWDER
Uses
Benzenesulfonyl hydrazide is used in making foam rubber and foam plastics.
Production Methods
Benzenesulfonyl hydrazides are produced by treating benzenesulfonyl chlorides with hydrazine in dioxane, alcohol, or water and in the presence of a second equivalent of hydrazineoranotherbase. They react with nitrous acid to form benzenesulfonyl azides according to the following equation:
ArSO2NHNH2 +HNO2→RSO2N3 +2H2O
General Description
Benzenesulfonyl hydrazide is a white to light-colored crystalline solid. Insoluble in water and denser than water. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion. Readily ignited by sparks or flames and burns vigorously. Used to make other chemicals.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Self-decomposition or self-ignition may be triggered by heat, chemical reaction, friction or impact. May be ignited by heat, sparks or flames.
Safety Profile
Poison by ingestion. A flammable solid. When heated to decomposition it emits toxic vapors of NOx and SOx.
