2-METHYL-2-PROPENE-1,1-DIOL DIACETATE Chemical Properties,Usage,Production

Chemical Properties

Liquid.Slightly soluble in water. Combustible.

Uses

Chemical intermediate, can provide controlled release of methacrolein in acid solution.

General Description

A liquid. Density 1.04 g / cm3; highly toxic.

Reactivity Profile

2-METHYL-2-PROPENE-1,1-DIOL DIACETATE reacts exothermically with acids. Strong oxidizing acids may cause a reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated with basic solutions. Flammable hydrogen may be generated by mixing with alkali metals and hydrides. Reacts readily with mercaptans. Acidic conditions favor breakdown to methacrolein, which is subject to possibly vigorous polymerization.

Fire Hazard

When heated to decomposition, 2-METHYL-2-PROPENE-1,1-DIOL DIACETATE emits acrid smoke and irritating fumes.

Safety Profile

Poison by inhalation, skin contactand intraperitoneal routes. Moderately toxic by ingestion. When heated to decomposition it emitsacrid smoke and irritating fumes.
