摘要
Abstract
There is high sensitivity of infrared spectrum for urotropine and no interference between the infrared absorption peaks of urotropine(1007 cm–1 )and commercial phenolic resin powder(1509 cm–1 ). So,it is feasible to determine the content of urotropine in phenolic resin powder used in abrasive tools by infrared KBr tabletting method.The content of urotropine in phenolic resin powder is analyzed quantitatively by external standard method(ESTD) and internal standard method (ISTD) respectively and also compared with chemical titration method(perchloric acid titration).The results show that the relative standard deviation of the content determination of urotropine in phenolic resin powder by infrared spectrometry is less than 2%.The accuracy of this method meet the requirement of GB∕T 24412- 2009.This method is simple and reliable,which can be applied to measure the content of urotropine in phenolic resin powder for abrasives industry.关键词
