These products and intermediates were identified through MS， NMR and HPLC. Interfacial tensions of surfactants/alkali and crude oil were determined by Model一500 spinning drop tensiometer. The effects of concetrations and structures of surfactants and alkality on interfacial tensions were discussed. HY and H } zeolites were choosed as catalysts for the alkylation of naphthelene, considering friendly environment and industrialization HY was confirmed to have higher activity. 夕 目 录 第一章 第二章 前言·… 文献综述 表面活性剂在三次采油中的应用 1三次采油及化学驱油体系简介 ..................…… 表面活性剂的微观驱油机理“·“·… 表面活性剂的筛选及常用表面活性剂 ..……O…… 2 .1 .3 …‘...……，.4 2.2烷基蔡磺酸盐的合成····“··““·“··”“·”·“···”·“·7 2.2.1蔡的烷基化························“·······”·····……7 2.2.1.1烷化剂和催化剂简介····“·“·，.·”·“····””·一7 2.2.1.2以分子筛为催化剂烷基化“·“··““·“·”·“··““·7 2.2.2烷基蔡的磺化·.. ... ... ... ... ... ... ... ... ... ... ... ... ... ... 15 第三章总论“. ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... 17 3.1系列烷基蔡磺酸盐的合成及提纯“. ... ... ... ... ... ... 17 3.1.1蔡的烷基化反应·. ... ... ... ... ... ... ... ... ... ... ... ... 18 3.1.1.1以A1C13为催化剂合成烷基蔡”·”···“···“一18 3.1.1.2以分子筛为为催化剂合成烷基蔡... ... ... ... ... .. 3 4 3.1.2磺化反应“. ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... 3 8 3.1.2.1浓硫酸磺化·. ... ... ... ... ... ... ... ... ... ... ... ... ... 3 8 3.1.2.2发烟硫酸磺化·.. ... ... ... ... ... ... ... ... ... ... ... ... .. 3 9 3.1.3表面活性剂的分离及提纯“. ... ... ... ... ... ... ... ... 41 3.1.3.1已基、辛基烷基蔡磺酸盐的提纯·. ... ...
