摘要

The thermal reactions of 1, 5, 5-and 3, 5, 5-trimethyl-1, 3-cyclohexadiene, 5, 5-dimethyl-: 3- methylenecyclohexene and 5, 5-dimethyl-l, 3-cyclohexadiene over quartz chips at 300-530O and atmospheric pressure were studied. It was found that at 300-400', 1, 5, 5-and 3, 5, 5- trimethyl-1, 3-cyclohexadienes reversibly isomerize. 4 t 500" a mixture of the latter dienes yielded mostly m-xylene, meiitylene and 1, 3, 5-trimethyl-1, 3-cyclohexadiene. 5, 5- ...
