摘要
本文对难以分析的有机高分子聚醚化合物羟值的测定,提出了设备简单、快速适用的醋酐—丙酮法。文中叙述了此法的原理、操作程序,并对其稳定性进行了讨论。
In this paper, We advanced a new method called 'acctic anhydride-acetone for determin hydroxyl value of macromolccular cthcr compound that is difficult to determin with genaral method. This method is quick, suitable and simple In this paper, We narrated the principle operation program of this method and discuss about its stability.
