| Popis: | Surfactants are used in various industries: in foods, pharmaceuticals, textiles, personal care products, detergents, polymers, paints and coatings, etc. Scientific researches of technological and ecological aspects of surfactants (sugars fatty acids esters) production are carried out. Traditionally, sugars fatty acids esters are synthesized by chemical methods (using high temperature and pressure, in the presence of basic or acid catalysts and organic solvents). Replacing chemical catalysts with enzymes is an example of “green” production. Various approaches to the use of a non-aqueous medium for biocatalytic esterification are reviews. The most ecological approach is determined – esterification in a solvent-free environment, which ensures improved enzyme activity retention, the absence of costs associated with solvent usage and recovery, facilitates further product purification, reduces the impact on the environment, increases safety in the workplace. |
