Химические свойства

colourless liquid

Использование

Neopentyl Glycol Diglycidyl Ether is used in preparation of aqueous Epoxy curing agents for orange peel-like leveling coatings.

Методы производства

The ether is made by condensing neopentyl glycol with epichlorohydrin followed by dehydrochlorination with caustic.

Общее описание

Clear liquid.

Реакции воздуха и воды

Slightly soluble in water.

Профиль реактивности

Neopentyl glycol diglycidyl ether is a ether-alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

Пожароопасность

Neopentyl glycol diglycidyl ether is combustible.

Канцерогенность

A 2 year dermal carcinogenicity study of NPGDGE in C3H mice was conducted at dose levels of 0.94, 1.87, and 3.75 mg/mouse . Skin tumor incidences were 10/50, 6/50, and 0/50 at 3.75, 1.87, and 0.94 mg/ mouse; no tumors occurred in the 300 acetone-treated controls. Tumor potency was calculated to be 1/700th that of benzo[a]pyrene, which was tested concurrently.
