Disclosed are multifunctional compounds represented by structural formula (I): ##STR00001##
methods of producing compounds represented by structural formula (I) and their use in inhibiting corrosion in corrodible material.

The present invention relates to extracted plant lipid, comprising fatty acids in an esterified form.

The invention relates to a method for processing black liquor soap, particularly to a method for producing and recovering fatty acid esters and resin acids from black liquor soap. The method is based on a catalytic selective esterification of the soap.

A nutritional composition for providing a source of butyrate or butyric acid comprising a compound having the formula (1) wherein R.sup.6 is along chain fatty acid having between 16 and 20 carbons.

##STR00001##

Processes for transesterifying wax esters. Implementations may include: providing a feedstock including wax esters, contacting the feedstock with a lipase, and catalytically transesterifying the wax esters in the feedstock with the lipase to form a transesterified product. An oxidative stability index (OSI) of the transesterified product may be greater than an OSI of the feedstock.

Lipids can be extracted from a microbial biomass that constitutes at least 20% lipids by weight and has a moisture content of less than 4% by weight by applying pressure to the biomass so as to release lipids therefrom, thereby leaving a biomass of reduced lipid content; and collecting the lipids.

Suggested is a composition with stabilized taste and/or odor, comprising (a) at least one acetophenone derivative of formula (I) wherein R.sub.1 stands for hydrogen or methyl, and R.sub.2 stands for hydrogen, hydroxyl or a —OCH.sub.3 group, or a cosmetically pharmaceutically acceptable salt thereof, and (b) at least one mono- or polyunsaturated C.sub.8-C.sub.22 fatty acid or its monohydric polyhydric C.sub.1-C.sub.18 alkyl alcohols ester. ##STR00001##

A microorganism oil composition, in particular of microalgae, enriched with polyunsaturated fatty acids, characterised in that it has a saturated fatty acid content of less than or equal to 40 mg/g of composition, an omega-3 polyunsaturated fatty acid content greater than or equal to 500 mg/g of composition, and in that it includes, with respect to the total quantity of monoglycerides, diglycerides, triglycerides and fatty acid ethyl esters, a quantity of triglycerides below 70%, a quantity of diglycerides of between 10 and 35%, and a quantity of monoglycerides of between 1 and 5%.

The present invention concerns a catalyst and pre-treatment process for acidic charges consisting of sulfated zirconia and cerium for the production of biofuels, characterized in that the catalyst has greater activity and resistance to deactivation with acidic charges.

The invention relates to a composition comprising: at least one alkane-sulphonic acid R—SO.sub.3H wherein R represents a saturated, linear or branched, hydrocarbon chain comprising from 1 to 4 carbon atoms, which can or cannot be substituted by at least one halogen atom; sulphuric acid; and optionally at least one solvent;
of which the proportions are defined in the description. The invention also relates to the use of the composition as a fatty acid esterification catalyst.
