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

Modified process for the direct production of alkyl glycosides

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.

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.

A process for the preparation of alkali metal salts of ether-carboxylic acids by oxidation of etheralcohols in an aqueous phase with oxygen or gases containing oxygen at elevated temperatures in the presence of alkali metal hydroxides and noble metal catalysts, in which an aqueous solution, containing an alkali metal hydroxide solution, of the ether-alcohols is brought into contact in a thin layer on a solid carrier or in the form of fine particles with oxygen or the gases containing oxygen as a continuous phase, the concentration of the ether-alcohols in the aqueous phase being in the range from 0.1 to 15% by weight, based on the total weight of the aqueous phase, enables aqueous solutions of the alkali metal salts of the ether-carboxylic acids in high concentrations to be prepared.

Substituted diphenols, phenyl ethers containing two oxygen atoms attached to a benzene nucleus, and naphthols are more practically effective than previously known additives in stabilizing tin (II) salts, in electrolyte solutions useful for coloring anodized aluminum by electrolysis therein, against oxidation to tin(IV) by reaction with ambient oxygen. Preferred additives include 2-tert-butyl-1,4-dihydroxybenzene, methylhydroquinone, trimethylhydroquinone, 4-hydroxynaphthalene-2,7-disulfonic acid, and p-hydroxyanisole. If p-toluenesulfonic acid or napthalene sulfonic acid are also used in the electrolyte, the throwing power can be greatly improved.

An improvement in the process for chlorination and sulfochlorination of liquid or dissolved organic components, wherein the gases are intensively mixed with the liquid organics until substantially no gases remain unmixed, and the mixture is then reacted.

Process for the chlorination and sulfochlorination of organic compounds

A process for reacting nitroparaffins with formaldehyde in the presence of potassium hydroxide by aldol condensation which can be carried out continuously or discontinuously and on a large scale. This is achieved by mixing the nitroparaffin, aqueous aldehyde solution and potassium hydroxide in the absence of organic solvents and carrying out the reaction while maintaining the temperature between -5.degree. and +20.degree. C.

Aldol condensation of nitroparaffins

The invention seeks to improve the preheating resistance and high temperature resistance during vulcanization of a cement for the vulcanization of rubber onto metals. Such cements conventionally contain metal-binding polymers, dinitrosobenzene, organic solvents and, optionally, other components, such as acid-binding agents and reinforcing fillers. The goals of the invention are achieved by partial replacement of the usual metal-binding polymers by substituted aromatic compounds bearing two or more substituent groups having the formula --CH.sub.2 Br.

A process for the preparation of geminate bromo-nitro-alcohols by the bromination of alkali metal or alkaline-earth metal salts of nitroalcohols in aqueous solution, while cooling the reaction mixture so that the maximum reaction temperature does not exceed 30.degree. C. In carrying out the reaction, the aqueous solution of nitroalcohol salt is added to a mixture of bromine and aqueous hydrobromic acid.
