In an attempt to lower processing costs of producing cyclic fatty acids by a high‐temperature alkali treatment, water was tested as the reaction solvent instead of ethylene glycol, previously used. Based on extensive tests in a high‐pressure autoclave, saturated cyclic (cyclohexanoic) fatty acids were produced under economic reaction conditions, including a temperature of about 300C; a 4:1 solvent ratio and 50% excess sodium hydroxide catalyst. The lower yield of saturated cyclic fatty acids by the water process is more than offset by the fewer steps and reduced evaporation costs.
