Method for producing of 2,3-dimethylbutene-1 and 2,3-dimethylbutene-2

There is provided a process for producing an alkenyl-substituted pyridine derivative using, a solid base catalyst which is obtained by heating a metal oxide selected from the group consisting of alumina, an alkaline earth metal oxide and a hydrotalcite with

Process for producing alkenyl--substituted pyridine derivative

2,3-Dimethyl-2-butene is prepared by isomerizing 2,3-dimethyl-1-butene using at least one acid selected from the group consisting of sulfuric acid and sulfonic acids. By this process, 2,3-dimethyl-2-butene is effectively prepared from 2,3-dimethyl-1-butene using an inexpensive catalyst such as sulfonic acid or the sulfonic acids. Further, a dimerization reaction product of propene can also be used in the isomerization step without removing the dimerization catalyst from the reaction product.

Process for preparing 2,3-dimethyl-2-butene

A process is disclosed for producing an amine by carrying out a reductive amination of a cyclic ketone or by carrying out a reduction of an imino derivative of a cyclic ketone to the corresponding amine which process is characterized in using a cobalt catalyst containing a carbonate of an alkaline earth metal and/or lanthanum oxide.

Process for producing amines

Amines are produced in high yield by the process which comprises allowing a cyclic ketone to react with ammonia in the presence of active carbon to produce imino derivatives and then, allowing the imino derivatives to react with hydrogen in the presence of a hydrogenating catalyst.
