摘要:
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.

A cleaning preparation for cleaning hard surfaces including at least one alkoxylated fatty alcohol corresponding to general formula (I): R—O—(CnH2nO)m—H (I) in which R is a linear or branched, saturated or unsaturated, alkyl or alkenyl group containing at least 19 carbon atoms, m represents a value of 20 or more, and n represents 2 or 3 is provided. A surfactant mixture including at least one compound corresponding to the above general formula (I), and at least one additional compound is also provided. A liquid rinse agent including water; a solubilizer; and at least one alkoxylated fatty alcohol corresponding to the above general formula (I), where the at least one alkoxylated fatty alcohol corresponding to general formula (I) is present in quantities of from about 0.1 to about 25% by weight of the rinse agent is also provided.
摘要:
The invention relates to a process for the enzymatic synthesis of esters of polyunsaturated, short-chain or sensitive fatty acids with a high triglyceride content, which is made up of an enzymatic synthesis of the mixture of triglycerides and partial glycerides starting from free fatty acid, methyl or ethyl esters and glycerol, a subsequent selective enzymatic back-hydrolysis of the partial glycerides to fatty acid and glycerol and distillation-based separation of the triglycerides, and to the triglyceride-rich ester mixtures obtainable by this process. The process is preferably carried out as a one-pot process in the same reactor and in the presence of the same enzyme.

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 CH2—CH2 or CHR—CH2, R, R′ or R″ 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″′ and R″″ 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′ and X″ 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.

摘要:
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.
