Abstract
Hexanoic acid 2-(diethylamino) ethyl ester(DA-6),a plant growth regulator,was prepared from hexanoic acid and N,N-diethylamino ethanol by using cation resin as catalyst in toluene.The optimum synthesis technique condition was obtained by orthogonal experiment.When the mol ratio of acid and alcohol was 1.2:1 and the dosage of catalyst was1.7 %,the reaction yield could reach 93.5 % after 6 hours with the purity of 95 %.Meanwhile,the preparation of DA-6 citrate was also studied.
