Methyldihydroxyethylbenzyl ammonium chloride(MDBAC)was synthesised with MDEA and benzylchloride as raw materials under the irradiation of constant power microwave.The qualitative analysis of the product was carried out with HLC.The structure of the product was characterized with IR
1H NMR and 13C NMR.Through response surface methodology (RSM)
the mathematical relational model between conversion and affecting factors was established
and the microwave synthesis technique of MDBAC was optimized.Under the optimized conditions
the reaction rate was 60 times of the conventional method.The critical micelle concentration (CMC)
surface tension
Krafft point and melting point of the product were determined.
