摘要: In the isomerization of olefins by contacting a linear, isomerizable olefinic hydrocarbon with a catalyst to the corresponding linear, isomerized olefinic hydrocarbon, a process wherein the catalyst is an alkaline catalyst composition prepared by heating an alkali metal, an alkali metal hydroxide and alumina at a temperature higher than the melting point of the alkali metal. By the use of the said catalyst composition, the isomerization can be accomplished much more efficiently, compared with the case of using conventional catalyst compositions.

摘要: A process for preparing alkyl trans-chrysanthemate which comprises treating the corresponding cis-isomer with a catalyst selected from the group consisting of (1) an alkali metal catalyst, (2) an alkaline catalyst composition prepared by reacting an alkali metal, an alkali metal hydroxide and alumina at a temperature higher than the melting point of the alkali metal and (3) an alkali metal hydride catalyst. By this process, the objective trans-isomer is obtainable in an excellent yield with ease.

摘要: 5-ISOPROPYLIDENE-2-NORBORNENE IS PRODUCED BY SUBJECTING CYCLOPENTADIENE AND 2-METHYL-3-BUTENE-2-OL TO DIELSALDER REACTION TO OBTAIN A,A-DIMETHYL-5-NORBORNENE-2METHANOL (A MIXTURE OF ENDO-FORM AND EXO-FORM), DEHYDRATING THE A,A-DIMETHYL-5-NORBORNENE-2-METHANOL TO FORM A MIXTURE OF ENDO- AND EXO-5-ISOPROPENYL-2-NORBORNENE MIXTURE CONTAINING, IN PART, 5-ISOPROPYLIDENE-2-NORBORNENE, AND CONTACTING THE MIXTURE WITH AN ALKALINE CATALYST. THE 5-ISOPROPYLIDENE-2-NORBORNEN IS USEFUL AS A TERMONOMER OF A SO-CALLED ETHYLENE-PROPYLENE TERPOLYMER RUBBER, AND THE INCORPORATION THEREOF RESULTS IN A TERPOLYMER HAVING EXCELLENT CURING CHARACTERISTICS.
