Diethyl allylamine (DEEA) was synthesized by using allyl chloride (AC) as alkylation reagent at normal pressure without catalysis. The effects of the material proportion, the feeding method and the boiling time upon the yield of diethyl allylamine were investigated. The results show that the yield can reach 78% under the following optimal conditions: the molecular ratio of allyl chloride:diethyl amine = 1.1:1, t...
