METHOD OF PREPARING LOWER KETONES Russian patent published in 1998 - IPC

FIELD: chemical industry. SUBSTANCE: lower ketones are prepared by liquid phase dehydrogenation of secondary alcohols in the presence of stationary catalyst such as metallic nickel or hydrogen activated nickel containing metal or carrier supported nickel in C₁₂-C₂₀, paraffins which are used as dehydrating agent solvent in the process medium for activation of catalyst and heat carrier. Lower alcohol flow is directed counter or directly to flow of paraffins admitted into reactor on top or below catalyst bed. EFFECT: lower power consumption and lower consumption of reagents, increased yield of product (up to 99.8 %) and simplified technology. 3 cl, 3 dwg, 9 ex, 2 tbl
