    • A method is disclosed for producing purified trimesic acid prepared by a process involving the liquid-phase oxidation of mesitylene in a solvent consisting of an aliphatic C.sub.2 -C.sub.6 monocarboxylic acid, water or a mixture thereof in the presence of an oxidation catalyst comprising cobalt, manganese and bromine components, crystallizing crude trimesic acid by cooling to about 80.degree. C. to about 150.degree. C., separating crystallized trimesic acid from the mother liquor at a temperature in the range of 80.degree. C. to about 105.degree. C. and washing the separated crude trimesic acid crystals with water at a temperature of from about 10.degree. C. to about 100.degree. C.

    • Cyclization of aliphatic moieties of 3-20 carbons which comprises contacting a suitable starting compound comprising the aliphatic moiety with a catalyst comprising at least one member selected from the group consisting of copper aluminum borate and zero valent copper on a support comprising aluminum borate under appropriate reaction conditions to obtain a compound having at least one more cyclic moiety than the starting compound. Preferably, the aromatic which undergoes cyclization is an alkenyl group attached to an aromatic nucleus. The present invention can be used to dehydrocyclize alkenylbenzenes to alkylnaphthalenes. In particular, 5-(o-tolyl)pentene can be dehydrocyclized to mixtures of 1,5-, 1,6-, and 2,6-dimethylnaphthalene.
    • 包括3-20个碳的脂族部分的环化,该方法包括使包含脂族部分的合适起始化合物与包含选自硼酸铜铝和零价铜中的至少一种的催化剂在包含硼酸铝的载体上进行适当反应 获得具有比起始化合物至少多一个环状部分的化合物的条件。 优选地,经历环化的芳族化合物是连接到芳族核的烯基。 本发明可用于将烯基苯脱氢环化成烷基萘。 特别地,5-(邻甲苯基)戊烯可以脱氢环化为1,5-,1,6-和2,6-二甲基萘的混合物。
