Abstract
554,889. Alumina catalysts. FEACHEM, C. G. P., SWALLOW, H. T. S., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 19, 1941, No. 16393. [Classes 1 (i) and 1 (iii)] An alumina catalyst for dehydration and deammination reactions is obtained by precipitating sodium aluminate solution with sodium bicarbonate, washing and drying the precipitate, and heating it to 300-400C.
