Cationic etherifying agent ( CHPTMAC) is an important agent to etherify natural polymers such as starch. 阳离子醚化剂(CHPTMAC)是淀粉等天然高分子进行阳离子改性的重要单体。
Use Etherify Starch ASP in Sizing for Fine Cotton Yarn 用ASP变性淀粉于细号纯棉纱上浆
Nitrogen-Heterocycles Grafted Chitosan Polymer ( NVP-CTS) was Synthesized by treating chitosan whit H_2O_2-Fe~ ( 2+) as initiator and N-vinylpyrrolidone ( NVP) as Etherify agent. The resultant NVP-CTS had been identified by means of IR and elemental analysis. 以Fe2+-H2O2为引发剂,N-乙烯基吡咯烷酮为醚化剂,将壳聚糖进行醚化改性,得到接枝含氮杂环化合物壳聚糖(NVP-CTS),并通过红外光谱和元素分析证实了接枝化合物的存在。
Span-80, a typical polyalcohol non-ionic surfactant materials, was the product of inner etherify of sorbitol dehydration and esterifying with oleic acid. 山梨醇酐单油酸酯(Span-80)是一种典型的多元醇型非离子表面活性剂,由山梨醇失水内醚化并与油酸发生酯化反应生成。
