| titleOfInvention | Method for production of trans-alkyl-substituted cyclohexanecarboxylic acids |
| abstract | FIELD: organic chemistry. n SUBSTANCE: invention relates to improve method for production of trans-alkyl-substituted cyclohexanecarboxylic acids of general formula 1 , wherein R is C 1 -C 10 -alkyl and trans-4-(C 1 -C 10 -alkyl)cyclohexyl radical, by hydration of respective 4-alkyl-substituted benzoic acids. In aqueous-alkali solution at elevated temperature and elevated hydrogen pressure of 0.5-15 MPa in presence of catalyst followed by isomerization at 200-400°C and isolation of reaction products by mixture acidifying. As catalyst ruthenium-nickel catalyst on carbon carrier is used, wherein catalyst contains 5 mass % of metal calculated as total catalyst mass and Ni/Ru mass ratio is (0.01-1.5):(8.5-9.99). Process is carried out at 20-150°C for 0.25-1 h, and isomerization is carried out in inert gas atmosphere in several steps after mixture filtration to separate catalyst. Compounds of present invention represent value products in production of liquid crystal materials and biologically active materials. n EFFECT: accelerated process with reduced cost and increased effectiveness. n 1 tbl, 9 ex |
