摘要
研究了环氧值的表征,优化了时间、温度和盐酸-丙酮溶液的过量百分数等因素,并确定了乙醇-水-氢氧化钠溶液的配制比例,将环氧值的滴定步骤具体化,从而更加精确地测定环氧值。
This article mainly discusses the characteristic of epoxy value. The factors (such as time,temperature and the superfluous scale of hydrochloric acid-acetone solution)are optimized,and the confecting proportion of ethand-water-sodium hydroxide solution also confirmed. Titration step is shown clearly so that the more precise epoxy value could get.
