Microwave synthesis technique and properties of octadecylmethyldihydroxyethyl ammonium bromide
摘要
Abstract
Octadecylmethyldihydroxyethyl ammonium bromide ( OMDAB ) was synthesized with N-methyldiethanolamine and octadecylbromide as raw materials under microwave condition. It was analyzed quantitatively with two-phase titration and characterized with IR, 1H NMR and elemental analysis. The effects of solvent, microwave power, reaction time, and solvent volume on the conversion rate were studied. The optimal condition obtained through response surface methodology (RSM) is as follows: with hexanol as solvent, solvent volume of 10. 7 ml, reaction time of 25 min, and microwave power of 570 W. Under the optimal condition, in a very short reaction time, just 4. 63% of the conventional heating time, the conversion can reach 95. 30%. The surface tension, Krafft point, CMC and the melting point of the product are determined.关键词
