The new process of producing adamantane compounds
Abstract
Tricyclo (5.2.1.0/sup 2,6/) decane was preferably rearranged to adamantane over sodium Y type zeolite exchanged with 28.4-58.7Vertical Bar3< lanthanum(III), either alone (at 250/sup 0/C) or as a support for a 0.75Vertical Bar3< platinum/0.25Vertical Bar3< rhenium (250/sup 0/C) or platinum-rhenium-cobalt catalyst. The zeolitic catalysts were superior to several aluminum halide and platinum/alumina catalysts tested, since the zeolites exhibited sufficient activity, a longer life, and easier regenerability, via hydrogen treatment at 400/sup 0/C. For industrial use, 1,3-dimethyladamantane was preferably synthesized by hydroisomerizing tetracyclo (6.2.1.1/sup 3,6/0/sup 2,7/) dodecane (TCDD, made from ethylene and dicyclopentadiene) at 250/sup 0/C over Vertical Bar3: 50Vertical Bar3< lanthanum-exchanged zeolite either alone or as a support for 3Vertical Bar3< nickel, 0.75Vertical Bar3< platinum/0.25Vertical Bar3< rhenium, or platinum-rhenium-nickel, and also over silica/alumina-supported platinum-rhenium-nickel. DMA was also synthesized by isomerizing cyclododecatriene to acenaphthenes, such as perhydroacenapthene (PHA), over Y zeolites exchanged with lanthanum(III) or calcium(II), and in a second step, isomerizing PHA over platinum-rhenium-nickel supported on lanthanum zeolite.
