General Description
Colorless liquid.
Reactivity Profile
HEPTYL ACETATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Health Hazard
May be harmful by inhalation, ingestion or skin absorption. Irritating to eyes, skin, and mucous membrane.
Fire Hazard
Special Hazards of Combustion Products: When heated to decomposition, HEPTYL ACETATE emits acrid smoke and fumes.
