Process for the production of alkyl and/or alkenyl oligoglucosides

Process for the production of lower alkyl oligoglucosides

Water-based surfactant pastes, more particularly those containing nonionic surfactants of the alkyl glycoside type, are effectively stabilized against microbial infestation if, after oxidative bleaching to eliminate alkali-sensitive color bodies, they are adjusted to a pH value of at least 11 by addition of alkaline substances.

The crude reaction products from the synthesis of alkyl glycosides are bleached by kneading the material substantially freed from the excess fatty alcohol and containing at most limited quantities of water with an oxidizing agent at such elevated temperatures that the reaction mixture lends itself to plastic processing. Temperatures of from about 50.degree. to 150.degree. C. are particularly suitable, although it is best to apply temperatures in the range from about 80.degree. to 100.degree. C. using aqueous hydrogen peroxide as the oxidizing agent. Bleaching is carried out under basic conditions, optionally by addition of an alkaline compound, such as for example 50% sodium hydroxide solution. The bleached product accumulates in the form of a solid. It is preferably mixed with typical compatible solids, more particularly typical constituents of detergents and cleaning preparations, to form a solid and preferably free-flowing alkyl glycoside compound.

Process for the production of alkyl and/or alkenyl oligoglycosides

Light-colored alkyl or alkenyl oligoglucosides are obtained by a process in which glucose or aqueous starch degradation products are reacted with fatty alcohols in the presence of acidic catalysts which are obtained by partial sulfation of C.sub.4-22 fatty alcohols.

The use of a fatty oil ex Helianthus annuus containing 78 to 92% by weight oleic acid and 2 to 10% by weight linoleic acid for the production of diperazelaic acid, with elimination of enrichment steps with respect to the oleic acid content, by fat splitting, distillation, oxidative ozonolysis of the fatty acid mixture obtained, and reaction of the azelaic acid thus obtained with hydrogen peroxide to form diperazelaic acid. The resulting diperazelaic acid has improved stability in storage and is obtained in high yields and in highly pure form.

Fatty oil ex helianthus annuus for the production of diperazelaic acid

A liquid detergent based on nonionic and anionic surfactants, and optionally particulate builder materials, contains a non-surfactant component which increases the wash efficiency, comprising the combination of low-polarity and mid- to high-polarity organic liquids. The low-polarity liquids are hydrocarbons, while the mid- to high-polarity liquids are esters, ethers, ketones or alcohols. The detergents have a satisfactory viscosity behavior, good miscibility with water and good wash efficiency.

A foam regulator consisting essentially of a mixture, applied to a particulate support material, of (a) 5 to 60% of a paraffin wax, (b) 20 to 90% of a microcrystalline paraffin wax which shows defined melting behavior as a function of temperature and (c) 5% to 20% of a diamide derived from C.sub.2 -C.sub.7 diamines and C.sub.12 -C.sub.22 fatty acids which is present in the paraffin mixture in very finely divided form. The mixture is preferably prepared by reaction of the diamines with the fatty acids in a molten mixture of components (a) and (b) in the presence of an acidic catalyst.

Bicyclic decanedioic acids corresponding to the following general formula ##STR1## in which R represents a C.sub.1 -C.sub.22 alkyl radical, a C.sub.2 -C.sub.34 alkylcarbonyl radical, or a residue of a polyalkoxylated C.sub.2 -C.sub.22 fatty alcohol, represent a new class of dicarboxylic acids which are useful as flotation aids in the flotation of non-sulfidic ores.

A process for the ozonization of unsaturated organic compounds in a reaction column through which the unsaturated compounds--in solution in a protic solvent--and an ozone-containing carrier gas and an inert coolant are passed downward in co-current flow to provide for an improved coolant effect and an increased ozonization yield where the coolant comprises a compound gaseous or liquid at ambient temperature with a boiling point preferably in the range from +20.degree. C. to -200.degree. C. The boiling point of the coolant is preferably at least 5.degree. C. below the ozonization temperature.
