摘要
用固体^(13)C NMR研究了呋喃醇(FA)和FA与三-(2-羟乙基)-异氰酸尿酯(THEIC)缩聚磺化反应及其产物结构,考察了2-甲基呋喃封端的FA线型齐聚物与甲醛水溶液在相转移催化剂(C_4H_9)_4N^+I^-和与大量硫酸作用下的反应特点,探讨了主要参数对反应的影响,阐明了缩聚交联磺化反应的规律,确定了产物的结构。
The condensation and sulfonation of furfuryl alcohol (FA) and FA with iris (2-hydroxyethyl) isocyanurate (THEIC) and the crosslinking product structures were studied by means of solid-state ^(13)C NMR. The reaction of formalin with FA linear oligomer terminated by 2-methyl furan took place in the presence of the phase transfer catalyst (C_4H_9)_4N^+I^-. The reaction of the terminated oligomer with a large amount of sulfuric acid as well as the former reaction was examined. The effects of some main reaction conditions on the crosslinking condensation and sulfonation were also discussed.
