Abstract
N,N-Dimethylglycine hydrochloride was synthesized from chloroacetic acid and dimethylamine under microwave irradiation.The effects of material ratio,reaction temperature,microwave irradiaton power,microwave irradiaton time on the reaction were studied through single factor experiments.And the structures of the product was identified by means of IR.Under optimal reaction conditions as follows:n(chloroacetic acid)∶n(dimethylamine) 1∶3.0,microwave irradiaton power 500 W,reaction temperature 65℃ and microwave irradiation time 150 min,the yield of N,N-dimethylglycine hydrochloride reached 86.02%.
