Профиль реактивности
2-Butoxyethyl acetate is incompatible with the following: Oxidizers . 2-Butoxyethyl acetate is an 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.
Угроза здоровью
Inhalation of concentrated vapor may cause headache, nausea, dizziness. Liquid causes irritation of eyes and mild irritation of skin. Ingestion produces same symptoms as inhalation.
Профиль безопасности
Moderately toxic by
ingestion and skin contact. Mild skin irritant.
Flammable when exposed to heat, flame, or
oxidizers. To fight fire, use alcohol foam.
When heated to decomposition it emits
acrid smoke and irritating fumes. See also
ESTERS.
Синтез
2-Butoxyethyl acetate is prepared from Butanol and Ethylene chloride. using Sodium acetate as condensing agem. Subsequent Acetylation of the Glycol ether.
Методы очистки
Shake the ester with anhydrous Na2CO3, filter and distil it in a vacuum. Redistillation can then be carried out at atmospheric pressure. [Dunbar & Bolstad J Org Chem 21 1041 1956, Beilstein 2 IV 215.]
