• Metal cation-exchanged montmorillonite (Mn+-mont)-catalysed aromatic alkylation with aldehydes and ketones

  The alkylation of aromatic compounds with aldehydes and ketones in the presence of a variety of metal cation-exchanged montmorillonites (Mn+-mont; Mn+ = Zr4+, Al3+, Fe3+, Zn2+, H+, Na+) has been investigated. Al3+- and Zr4+-Monts are revealed to be effective as catalysts, while no reaction takes place with Na+-mont. Al3+-Mont-catalysed alkylation of phenol with several aldehydes produces mainly or almost solely the corresponding gem-bis(hydroxyphenyl)alkanes (bisphenols) in good yields, while that with several ketones affords selectively the corresponding alkylphenols in moderate to good yields. The alkylation always occurs at the carbonyl carbon without any skeletal rearrangement and the kind of products depends much on the steric hindrance of an electrophilic intermediary carbocation. The alkylation of anisole, veratrole and p-cresol proceeds well, while that of toluene, benzene, chlorobenzene and nitrobenzene scarcely occurs.

  在各种金属阳离子交换的蒙脱石（Mn+-mont；Mn+ = Zr4+、Al3+、Fe3+、Zn2+、H+、Na+）存在下，研究了芳香化合物与醛和酮的烷基化反应。发现Al3+和Zr4+蒙脱石是有效的催化剂，而Na+蒙脱石则不发生反应。由Al3+蒙脱石催化的苯酚与几种醛的烷基化反应主要或几乎只生成了相应的双（羟苯基）烷烃（双酚），产率良好；而与几种酮的烷基化反应则选择性地生成了相应的烷基苯酚，产率适中至良好。烷基化总是发生在羰基碳上，没有骨架重排，产物的类型很大程度上取决于亲电中间体的碳正离子的空间位阻。茴香醚、邻苯二甲醚和对甲酚的烷基化反应良好进行，而甲苯、苯、氯苯和硝基苯的烷基化反应几乎不发生。

  The present invention relates to a polyol, polyurethane resin, rigid polyurethane foam, preparation process thereof and a preparation process of a rigid polyurethane foam composite. The polyol used in the present invention comprises an epoxy resin base polyol, phenol resin base polyol component and aromatic amine base polyol component. The above polyurethane resin, foam and composite using above polyol as raw material have resistance to dissolution in a hydrochlorofluorocarbon and hydrofluorocarbon which are foaming agents having very low public hazards. The above-mentioned foam products have excellent physical properties equivalent to those of conventional polyurethane foams obtained by using chlorofluorocarbon as foaming agent, and hence are very useful as a thermal insulation material or a thermal insulation structure for refrigerators, freezers, insulation panels, ships and vehicles.
