"Will be of interest to a wide range of researchers in academia and industry. Anyone who wishes to utilize sustainable, easily controlled, high yielding and highly specific processes for the synthesis and production of fine organic compounds, petrochemicals, polymers, pharmaceuticals, etc. will see that clay mineral catalysts can often provide solutions for many such problems."-Chemistry in New Zealand, April 2019"An excellent book published by B.K.G. Theng, summarizes the new results of organic catalytic reactions of clay minerals based on a number of professional publications. The book is very important for researchers who are in the field of interface chemistry, catalysis, colloid and environmental chemistry."-Applied Clay Science Journal, 171 (2019) 133
