The disclosed invention refers to a process for obtaining fatty acid alkyl esters, rosin acids and sterols from crude tall oil (CTO), which is characterized by the following steps: (a) reacting the free fatty acids present in the CTO with lower alcohols; (b) esterifying the sterols in the CTO with boric acid or transesterifying the sterols with a catalyst; (c) separating the fatty acid lower alkyl esters and rosin acids from the remaining sterol borate esters or sterol esters of fatty acids to produce a stream of sterol esters; (d) separating the fatty acid alkyl esters from the rosin acids to produce a first stream of fatty acid alky esters and a second stream of rosin acids; and (e) converting the sterol esters into the free sterols to produce a third stream of free sterols.

Isosorbide monoesters according to the general formula (I) wherein R' or R&#x2033; represent a hydrogen atom, or an group CO&#x2014;R&#x2032;&#x2033;, with the proviso that one group R&#x2032; or R&#x2033; is a hydrogen atom, and R&#x2032;&#x2033; represents linear or branched, saturated or unsaturated alkyl- or alkenyl groups with 6 to 22 C-atoms are useful compounds in the preparation of all kind of detergents, in particular dish washing detergents or of cosmetic preparations. 

Isosorbide monoesters and their use in household applications

The invention relates to selected surface-active substances of groups a) and b), the surface-active compound a) being selected from compounds of general formula (Ia), wherein M represents a group CH&#x2014;CHor CHR&#x2014;CH, R, R' or R&#x2033; independently represent saturated, unsaturated, linear or branched alkyl groups or alkenyl groups with 6 to 22 C atoms, and the indices n and m independently can have values between 1 and 40, and/or compounds of general formula (Ib), wherein R&#x2032;&#x2033; and R&#x2033;&#x2033; independently represent saturated, unsaturated, linear or branched alkyl groups or alkenyl groups with 4 to 22 C atoms, and the indices n and m independently can have values between 1 and 40 and X&#x2032; and X&#x2033; independently represent H or saturated, unsaturated, linear or branched alkyl groups or alkenyl groups with 1 to 18 C atoms. The surface active substances of the invention, either on their own or combined with other nonionic surfactants, lead to dishwashing agents with an improved drying performance, especially in multifunctional agents for automatic dishwashers.

Processes for the enzyme-catalyzed production of triglycerides using polyunsaturated fatty acids, in which (a) the reaction of polyunsaturated fatty acids and/or Calkyl esters thereof with glycerol in vacuo in the presence of an immobilized enzyme to form their triglycerides is accelerated by addition of an additive from the group of weakly basic salts, complexing agents and ion exchangers and/or addition of a weakly basic salt and/or addition of an entraining agent in the form of a solvent or a gas and/or addition of glycerol-binding adsorbers and/or heat treatment of the partial glyceride intermediate product, (b) the immobilized enzymes are removed from the triglyceride by separation or filtration and (c) the remaining fatty acids and/or Calkyl esters thereof are removed from the triglyceride by distillation, refining or extraction.

Processes for the production of triglycerides of unsaturated fatty acids in the presence of enzymes

A higher-yielding process for the production of monoglycerides in which triglycerides are enzymatically reacted with a catalytic amount of an esterase, preferably lipase, that has been activated by the addition of alkaline salts, in the presence of linear or branched alcohols containing 1 to 8 carbon atoms, then the esterase may be deactivated and it and the remaining alcohol removed, with the monoglycerides thus produced useful in lubricants, fuel additives, and emulsifying constituents in foods, and cosmetic and/or pharmaceutical formulations.

Processes for producing branched compounds are described wherein a carbonyl compound is condensed in the presence of a catalyst selected from the group consisting of acids and bases, to form an &#x3b1;,&#x3b2;-unsaturated condensation product; and the &#x3b1;,&#x3b2;-unsaturated condensation product is hydrogenated.

Processes for preparing conjugated linoleic acid are described wherein a conjugated linoleic acid lower alkyl ester is subjected to hydrolysis in the presence of an enzyme to form a hydrolyzate comprising a conjugated linoleic acid and a lower alkanol, wherein at least a portion of the lower alkanol is continuously removed; the hydrolyzate is separated into an organic phase and an aqueous/alcoholic phase; and the conjugated linoleic acid is separated from the organic phase.

Processes for the simultaneous production of sterols and polar lipids, in which preparations of vegetable oil lecithin fractions are subjected to ultrafiltration and, on the one hand, the sterols in the permeate and, on the other hand, the polar lipids in the retentate are enriched. The permeate and retentate can subsequently be worked up by methods known per se.

Guerbet alcohols of the formula (I)CH(CH)CHRCHOH&#x2003;&#x2003;(I)wherein Ris a linear alkyl radical having n-1 carbon atoms and n is a number of from 5 to 11 are produced by a process which comprises contacting a fatty alcohol of the formula (II)ROH&#x2003;&#x2003;(II)wherein Ris a linear alkyl radical having from 6 to 12 carbon atoms with a carbonyl compound and an alkall metal hydroxide. The use of heavy metal catalysts usually associated with the production of Guerbet alcohols is avoided thereby reducing the potential for heavy metal pollution of the environment.
