Definitions
- Mono and diesters of fatty acids and polyhydroxy alcohols, particularly glycerin, are compounds widely used as emulsifiers or surfactants in the food, cosmetic and pharmaceutical industry. These compounds can be obtained in two different ways: A) by direct esterification between fatty acid and polyhydric alcohol; B) by transesterification between a polyhydric alcohol and a fat (triglyceride) or a fatty acid methyl ester. From an industrial point of view, transesterification processes are the most important for the preparation of mono and diesters of fatty acids and polyols. Transestererification is a reaction that takes place, as indicated in the scheme, between an ester (1) and an alcohol (2) giving rise to a new ester (3) and another alcohol (4).
- transesterifications can be catalyzed by both acids and bases.
- the use of basic catalysts is preferable, since the acids can cause, depending on the structure of the alcohols involved in the process, secondary reactions such as isomerizations or dehydrations.
- the preferred catalysts are conventional bases such as KOH, NaOH, alkaline alkoxides such as NaOC 2 Hs, NaO-tC 4 H 9 , or NaHC0 3 , Na 2 C0 3 , and Ca (OH) 2 . These types of catalysts are difficult to remove from the final product and are also not reusable.
- HW in US-2197339 describe a method for transesterification of coconut oil with glycerin using NaHC0 3 and Na 2 C0 3 as catalysts. They obtain a mixture of esters and salts of fatty acids that then react with different hydrochlorines such as glycerol hydrochlorine, resulting in the formation of a monoester and NaCl. Monta ⁇ ola Mart ⁇ nez et al. describe in the Spanish patent application P-9001084 "Procedure for the preparation of fatty acid monoesters with glycols" assigned to Kao Corporation, a method for transesterification of fatty acid esters with glycerin using as dry Na 2 C0 3 catalyst.
- the Transesterification between vegetable oils and polyols is carried out in the presence of a solvent (tert-butanol or tert-a-alcohol) at temperatures between 160-200 ° C and using basic catalysts such as salts (oxides, carbonate hydroxides, alkoxides and acetates ) of alkali and alkaline earth metals and nitrogen bases.
- basic catalysts such as salts (oxides, carbonate hydroxides, alkoxides and acetates ) of alkali and alkaline earth metals and nitrogen bases.
