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 ...
On 3 May 1944, a CIL sulfuric acid plant in Sudbury, Ontario was certified as unionized by Mine-Mill Local 598. [3] Because so many working-age men were fighting overseas in the armed forces, these plants employed large numbers of women. [4] At the Ajax DIL plant about 7,000 women filled more than 40 million shells. [5]
The C16 and C18 omega hydroxy acids 16-hydroxy palmitic acid and 18-hydroxy stearic acid are key monomers of cutin in the plant cuticle. [ 1 ] [ 2 ] The polymer cutin is formed by inter esterification of omega hydroxy acids and derivatives of them that are substituted in mid-chain, such as 10,16-dihydroxy palmitic acid.
In 1989, Hoechst Celanese moved to buy out the remaining shareholders of Hoescht Celanese Canada and thus to fully privatize the Canadian unit in a deal worth $210 million. [ 18 ] In 1998, in a $2.7 billion deal, Hoechst Celanese sold its Trevira division to a consortium between Houston -based KoSa, a joint venture of Koch Industries , IMASAB S ...
12-Hydroxyheptadecatrienoic acid (also termed 12-HHT, 12(S)-hydroxyheptadeca-5Z,8E,10E-trienoic acid, or 12(S)-HHTrE) is a 17 carbon metabolite of the 20 carbon polyunsaturated fatty acid, arachidonic acid. 12-HHT is less ambiguously termed 12-(S)-hydroxy-5Z,8E,10E-heptadecatrienoic acid to indicate the S stereoisomerism of its 12-hydroxyl ...
Ricinoleic acid, formally called 12-hydroxy-9-cis-octadecenoic acid, is a fatty acid. It is an unsaturated omega-9 fatty acid [ 1 ] and a hydroxy acid . It is a major component of the seed oil obtained from the seeds of castor plant ( Ricinus communis L., Euphorbiaceae ), the plant that produces ricin .
