Abstract: The present invention relates to a method of treating solid surfaces where a suspendable liquid mist provided with suitable surfactants is applied to the surface to be treated, and the liquid mist drops have a surfactant content of from 10 to 3000 ppm by weight, based on the total amount of solvent, and an average drop size (weight-average) of ?100 ?m and to the use of surfactant-containing suspendable liquid mists for deodorization, decontamination, disinfection, corrosion protection, preservation, the stripping of solid surfaces or the placing of beneficial animals and microorganisms onto these.

Abstract: Phosphoric acid is separated from aqueous solutions of thiamine phosphates which are obtained in the phosphorylation of thiamine, with or without subsequent partial hydrolysis, by a process in which the phosphoric acid is converted with a virtually water-insoluble or only slightly water-soluble tertiary amine into the corresponding salt and the latter is extracted with a virtually water-immiscible or only slightly water-miscible solvent of moderate polarity. In a particularly advantageous procedure, the phosphoric acid is extracted with a mixture of a virtually water-insoluble or only slightly water-soluble tertiary amine and a virtually water-immiscible or only slightly water-miscible solvent of moderate polarity.

Abstract: Thiamine monophosphate is separated from a solution of thiamine phosphates containing thiamine monophosphate and cocarboxylase and having a pH of 2-7 by using a cation exchanger resin having a pK.sub.a of 1.0-4.5.
