摘要:
A bioprocess for producing carboxylic acids, alcohols and aldehydes is provided by culturing Candida sp. in a fermentation medium containing various defined substrates.
摘要:
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.

Quaternary ammonium salts of fatty acid hydroxyalkanesulfonic acids are made by reacting a hydroxyalkanesulfonic acid of the formula (I):HO--(C.sub.n H.sub.2n)--SO.sub.3 H (I):wherein n=2 to 4 with a fatty acid having from 6 to 18 carbon atoms at a temperature range of from about 60.degree. C. to about 120.degree. C. and at a reduced pressure followed b reaction with an amine in an organic solvent.
摘要:
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.

Alkyl glycosides in admixture with bactericidally active alcohols or carboxylic acids in, e.g. aqueous treatment solutions, for potentiating the microbicidal effect thereof.
摘要:
Mixtures of alkyl glycosides and fatty alcohols are readily separated by distillation without thermal degradation of glycoside. In the presence of one or more viscosity-reducing agents which are heat-stable and color-stable at temperatures of up to 160.degree. C., which are miscible with the alkyl glycosides, which have a boiling point at 760 mbar at least 50.degree. C. above the boiling point of the fatty alcohol present in the mixture, and reduce the viscosity of the mixture to at most 10,000 mPas at the distillation temperature. The fatty alcohols are quantitatively separated off from this mixture by distillation in customary distillation apparatus at a temperature at least 20.degree. C. below the thermal decomposition point of the alky glycosides and under pressures of from 1 to 10.sup.-3 bar. The process is particularly applicable to the purification of reaction mixtures obtained from the preparation of alkyl glycosides from fatty alcohols and saccharides to provide a product comprising alkyl glycoside and viscosity-reducing agent directly useable is cosmetics and fabric detergents, dishwashing detergents and cleaning preparations.
摘要:
Detergents on the basis of anionic and nonionic surfactants contain as laundering power-enhancing additives an aliphatic amine compound which is selected such that its pK.sub.b value is at least equal to 14, minus the initial pH value of a 1% aqueous solution of the detergent containing the amine compound. Laundering power-enhancing amine compounds selected according to the rule mentioned are certain ether amines, amidoamines, glucamine derivatives or morpholine derivatives.
摘要:
The foaming and detergent power of manual dishwashing detergents gentle to the skin and containing anionic surfactants of the sulfonate or sulfate surfactant type, fatty acid alkanolamides and fatty alkylgucosides are enhanced by using fatty alkyl C.sub.12 -C.sub.14 monoglucosides containing less than 2 glucose units per fatty alkyl group in quantities of from 3 to 20% by weight alkyl sulfate or alkylether sulfate, and from 1 to 15% by weight fatty acid alkanolamide.
