Methyl Ester Hydrogenolysis. The flow sheet for the continuous methyl ester, catalyst slurry process is shown in Figure 1. The dry methyl ester, hydrogen, and catalyst slurry are fed cocurrently to a series of four vertical reactors operated at 250—300°C and 20,700 kPa (3000 psi). The reactors are unagitated, empty tubes, designed to provide adequate residence time, minimum backmixing, and a reasonable column height. Fresh catalyst powder is... 

Recently Bennet et al. (122) showed that the methyl ester of cholic acid forms small aggregates in relatively nonpolar organic solvents. These aggregates are made up of about four molecules of the methyl ester hydrogen bonded to one another through the hydroxyl groups and therefore might be considered as a form of reversed micelle. These derivatives do not form micelles in a more polar solvent, such as alcohol, but are present in true solution (122). 

The Philippines, a major producer of coconut oil, established its first oleochemical plant of limited capacity in 1967. The plant produced only 3,000 t/yr of coco fatty alcohols. Recent data for the Philippines listed a capacity of 25,0001 of alcohol products from coconut oil by the fatty acid hydrogenation process. Philippinas Kao produced 30,0001 of alcohol products from coconut oil using the methyl ester hydrogenation process.
