Popis:	1. It has been established that KCa-lubricants can be produced from soaps of HCO and technical 12-H(OH)St of different degrees of hydrogenation (iodine numbers ranging from 6.9 to33 g I2/100 g). The lubricants have good operation properties and their mechanical stability exceeds that of KCa-lubricants prepared from stearic acid and synthetic fatty acids. 2. Reduction of the iodine number of the saponifiable compounds improves the thickening action of the KCa-soap and hardly affects the thermal strength and the mechanical stability of the lubricants examined. 3. Utilization of technical 12-H(OH)St isolated from hydrogenated castor oil, instead of the hydrogenated oil itself, noticeably improves the thickening action of KCa-soap.
