A linear polyester is made by a process reacting polyols comprising at least two primary alcohol groups and at least one secondary alcohol or amino group and a dicarboxylic acid or a dicarboxylic acid ester in the presence of an effective amount of a lipase derived from Candida cylindracea, Candida lipolytica, Candida rugosa, Candida antarctica, Candida utilis, Chromobacterium viscosum, Geotrichum viscosum, Geotrichum candidum, Mucor javanicus, Mucor miehei, Porcine pancreas, Pseudomonas species, specifically Pseudomonas fluorescens, Pseudomonas cepacia, Pseudomonas pseudoalkaligenes, Pseudomonas alkaligenes, Thermomyces species, Rhizopus arrhizus, Rhizopus delemar, Rhizopus niveus, Rhizopus oryzae, Rhizopus javanicus, Aspergillus niger, Penicillium roquefortii, Penicillium camembertii or an esterase derived from Bacillus species, specifically Bacillus thermoglucosidasius; Mucor miehei, Horse liver, Saccharomyces cerevisiae, Pigs liver or combinations thereof. The secondary OH or amino group of the polyol moiety is unreacted.

Enzymatic synthesis of polyesters

Nitrogen-free corrosion inhibitors having a good buffering effect

Process for the production of alkyl glycosides

The aliphatic primary alcohols are reacted with a glycose, more especially glucose, in the presence of an acidic catalyst in certain process steps so that particularly light-colored and alkali-stable alkyl glucosides are obtained after a subsequent, compulsory bleaching step, which represents an improvement over known direct synthesis processes. The process may be carried out both on a laboratory scale and also on an industrial production scale.

Process for the direct production of alkyl glycosides

Detergent mixtures with improved processability contain 70 to 95% by weight of fatty acid isethionate salts, 5 to 30% by weight of fatty alcohols, 0 to 15% by weight of fatty acids, 0 to 15% by weight of alkyl and/or alkenyl oligoglycosides and 0 to 15% by weight of fatty acid N-alkyl polyhydroxyalkylamides, providing that the quantities add up to 100% by weight. The optionally self-emulsifying mixtures are suitable, for example, for the production of solid or liquid soaps.

Process for the production of alkyl and/or alkenyl oligoglycosides

A process for the production of surface-active alkyl glycosides which is carried out by the transacetalization method with butanol, leads to a new alkyl glycoside as end product which is characterized by high color-stability in alkaline medium; besides a high proportion of alkyl monoglycoside, the product also contains polyglycoside on polyglycose and butyl glucoside.

Telomerization of 1,3-butadiene

Alkadienyl ethers are prepared by the telomerization of conjugated dienes with polyols by continuous addition of the alkadiene to a reaction mixtue comprised of the polyol, secondary alcohol solvent, a portion of the alkadiene to be added, and low palladium catalyst concentration.
