Abstract: The caprolactam intermediate, 1,1''-peroxydicyclohexylamine, can be prepared by reacting cyclohexanone, with an aliphatic or alicyclic hydroperoxide and ammonia. In addition to the hexylamine intermediate, there is also formed as a by-product tbutyl alcohol.

Abstract: The reaction of isobutylene and methylal to form a mixture 1,3dimethoxy-3-methyl butane and 4-methoxy-2-methylbutene-1 and rearrangement of the same to yield isoprene and methanol is disclosed herein. The isobutylene and methylal may be obtained by the oxidation of isobutane to form t-butylhydroperoxide, followed by rearrangement of the hydroperoxide to yield methylal and tbutyl alcohol and dehydration of the alcohol to produce isobutylene.
