    摘要: 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.

    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.

    摘要: Free-flowing, particulate foam inhibitor concentrates, which suffer no loss of activity in admixture with surfactants or strong alkalis, are prepared by compacting a mixture of from 1 to 20% by weight of the foam inhibitor with 80 to 99% by weight of a water-soluble salt or salt mixture optionally containing blending aids and having a pH value in the form of a 1% aqueous solution of from 6 to 9.5 under elevated pressure and subsequently size-reducing the compactate to an average particle size of from 0.1 to 2 mm. The presssure applied to the mixture should not significantly exceed the pressure limit at which no further compaction occurs. In addition, the particle porosity, as measured by mercury porosimetry, should be below 10%. The foam inhibitors used are preferably paraffin hydrocarbons, organopolysiloxanes and mixtures thereof with finely-divided hydrophobic solids, particularly finely-divided silica.
