Amination of 1-octanol

In amination of 1-octanol the opportunity to get directly the amine via a n ucleophilic substitution reaction over metal phosphate catalysts (i.e. zirc onium, cerium or boron phosphates), or zeolites has been investigated. Ther eby, the dehydration of octanol is in competition with the amination. In co mparison the reductive amination on copper chromite and nickel oxide on sil ica or alumina as carrier was checked, too. Thereby, complete conversion, a s well as almost 100% selectivity to a mixture of 1-octylamine and octane n itrile are achieved. (C) 1999 Elsevier Science B.V. All rights reserved.
