Progress in Catalytic Technology in Japan

A review of the developments in catalytic technology made in Japan in recent years has been prepared by M. Misono and N. Nojiri (Appl. Catal, 1990, 64, (1-2), 1-30). It is suggested that the close co-operation between academic and industrial chemists is one of the factors that has contributed to the progress. Another is the effective application of new catalyst materials, such as heteropoly acids, new zeolites, bimetals and chiral transition metal complexes. One representative of each type, which is now used in a newly industrialised process, is described in some detail.

These include a novel palladium-tellurium on active carbon catalyst that has been developed for use during the diacetoxylation of 1,3-butadiene to 1,4-diacetoxyl-2-butene, under mild conditions, while a new asymmetric process for l -menthol production depends upon the use of optically active rhodium-BINAP to catalyse the enantioselective isomerisation of geranylchethylamine.
