Abstract
The present invention concerns a new nickel-rhenium catalyst and method of preparing said catalyst. The invention also relates to the catalytic amination of lower aliphatic alkane derivatives such as alkanemono-ols, alkanediols and alcoholamines utilizing the new nickel-rhenium catalyst.
Claims16
A catalytic composition having high activity and selectivity in the amination of lower aliphatic alkane derivatives to the corresponding alkylamine, said catalyst comprising rhenium, nickel and boron impregnated on a support material selected from the group consisting of .alpha.-aluminas, silicas, silica-aluminas, kieselguhrs, diatomaceous earth and silica-Titanias wherein the ratio of nickel to boron to rhenium is in the range of from about 2:2:1 to about 30:30:1 and the total nickel, boron and rhenium present is in the range of about 3 to about 30 percent by weight of the support material, wherein said catalyst is activated by reduction in the presence of hydrogen at elevated temperature.
A catalyst of high activity and selectivity useful for aminating lower aliphatic alkane derivatives to the corresponding alkyl amines, said catalyst prepared by impregnating a support material selected from the group consisting of .delta.-alumina, silica, silica-alumina, kieselguhrs, diatomaceous earths and silica - titanias with nickel, rhenium and boron to form a catalyst, and activating said catalyst by heating the catalyst in the presence of hydrogen at a temperature in the range of about 200.degree. to about 600.degree. C. for a period of from about 45 minutes about 4 hours to form an activated catalyst, wherein said activated catalyst contains a total nickel, rhenium and boron metal content in the range of from about 3 to about 30% by weight of the support material and the atom ratio of nickel to boron to rhenium is within the range of from about 5:5:1 to about 20:20:1.
