12-hydroxystearic acid is prepared by the hydrogenation of castor oil, followed by saponification with sodium hydroxide and acidification with hydrochloric acid. [3] This process converts ricinoleate moieties in castor oil triglycerides to 12-hydroxystearate, with stearate as a byproduct from dehydration of the hydroxy acid followed by ...
Oleic acid and linoleic acid are the other significant components. Some 270,000–360,000 tonnes (600–800 million pounds) of castor oil are produced annually for a variety of uses. [ 4 ] Castor oil and its derivatives are used in the manufacturing of soaps , lubricants , hydraulic and brake fluids , paints , dyes , coatings , inks , cold ...
