    摘要: A process for production of 1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane which comprises reacting phenol with 3,3,5-trimethylcyclohexanone in the presence of an acid catalyst, adding an aqueous solution of an alkali to the resulting reaction mixture to neutralize it, removing a water phase from the thus neutralized reaction mixture, cooling the resulting oil phase to crystallize phenol adduct crystals of 1, 1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane while obtaining a primary crystallization filtrate, wherein the primary crystallization filtrate is heated to a temperature of 150-250°C in the presence of an alkali catalyst in an inert gas atmosphere under a reduced pressure to thermally decompose 1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane in the primary crystallization filtrate.

    摘要: A process for the production of C 8 and higher olefins by the oligomerization of light olefins to heavier olefins is improved by the addition of cycloparaffins to the oligomerization zone. The recycle of the cycloparaffins extends the catalyst activity and improves the catalyst life.
