The results also demonstrated that the shorter EO chain of Triton X series surfactant, the greater the association constant with β-cyclodextrin. 另外,非离子表面活性剂环氧乙烷(EO)链越长,包结物稳定常数越小。
Introduce the practice and the main improvement in aspects of technology of pulp making of preparation, digester, washing and screening, short sequence bleaching of 0-D/ C-Eo-D of Fujian Yuexiu Shaowu Pulp& Paper Manufacturing Co. Ltd. 介绍了福建越秀邵武制浆造纸有限公司在备料、蒸煮、洗选、O-D/C-Eo-D短程漂等制浆工艺方面的实践及其主要改进。
The conductivity and relaxation of the solutions of LiClO_4 in dimethyl siloxane-ethylene oxide copolymer ( named DMS: EO: LiClO_4 for short) have been investigated systematically. 本文系统地研究了高氯酸锂的二甲基硅氧烷-环氧乙烷共聚物溶液(简写为DMS:EO:LiClO4)的电导和弛豫随温度和盐浓度的变化规律。
A random polyether was synthesized from ethylene oxide ( EO) and propylene oxide ( PO) using ( 1,2-) propanediol as initiator, and the influences of chain structure on the properties of the polyether were discussed. 论述了以丙二醇为引发剂,用环氧乙烷(EO)、环氧丙烷(PO)合成无规聚醚的方法,讨论了聚醚结构与性能的关系。
EO temperature 30 ℃. The yield of N-β-Hydroxyethyl-ethylenediamine can be increased to 86% and the purity of product can be increased to 99% through the special gas-liquid distillation column reactor which is suitable for this kind of reaction. 采用适合该反应的塔式精馏反应器,可使N-β-羟乙基乙二胺的收率达到86%,产品纯度达99%。
