Abstract: Novel 2-hydroxypropylimidazole derivatives of the formula I I where m is 1 or 2 and n is 0 or 1, R1 is an aliphatic or cycloaliphatic radical of 6 to 21 carbon atoms, R, if n is O, is an aliphatic, cycloaliphatic, aromatic or araliphatic radical of 6 to 21 carbon atoms and is preferably identical with R1, or R, if n is 1, is a divalent aliphatic or aromatic radical of 2 to 15 carbon atoms or is +TR p being 0 or 2, and R', R'' and R''' are hydrogen or alkyl of 1 to 4 carbon atoms, and R'' or R''' may also be nitro.

Abstract: Strongly alkaline, aq. solns. of nonionic surfactants are prepd. by adding, as solubilisers, ene-adducts, (I), of maleic anhydride to unsaturated 12-24C fatty acids or their triglycerides. Wt. ratio solubiliser:surfactant is 1:1 to 10:1. (I) prevent formation of a separate phase, e.g. at pH 9-12 and have a wide activity range. Solubilising activity is based on the simultaneous presence of hydrophilic carboxylate gps. and lipophilic mol. residue.

Abstract: Use as dielectrical impregnating fluids of benzenes or cyclohexanes, which may carry one or two methyl groups, or mixtures thereof which in addition carry long-chain secondary alkyl radicals.

Abstract: To prevent the salting-out of nonionic surfactants from strongly alkaline (pH>9) aqueous solutions, solubilizers have been proposed but existing solubilizers do not have a sufficiently broad action spectrum. The invention seeks to provide solubilizers having a broader action spectrum and provides for this purpose monocarboxylic acids of 6 to 11 carbon atoms optionally in admixture with ene-adducts of maleic anhydride and unsaturated fatty acids of 12 to 24 carbon atoms or their triglycerides. The solutions are useful as cleansers and in the textile industry.

Abstract: Dispersion dye prepns. contain (a) 5-40 wt. % one or more finely-divided dispersion dyes or optical brighteners, (b) 5-40 wt. % water-soluble surfactant from reaction of (i) ethylene oxide adducts of polyether diols made by polymerisation of butylene oxide T.H.F. or hexamethylene oxide in presence of acid or alkali, or (ii) adducts of ethylene oxide and propylene oxide on 2-10C diols, polyols and/or bis-(hydroxy cyclohexyl)methane or derivs., with 0.2-1 mol. chlorosulphonic acid, SO3 or sulpho-propionic anhydride per mol OH and subsequent neutralisation, (c) 5-30% usual anionic dispersant, and (d) 40-85% water opt. mixed with a water retention agent, or 10-90% (c) with no (d), and (e) opt. other usual additives. Used for dyeing or brightening of textiles contg. synthetic fibres, esp. wound yarns, e.g. cheeses, of cellulose ester or linear polyester fibres. The dispersions are stable and unchanged after prolonged storage at room temp. or many days at 60 degrees C. They are easily dispersed in water by stirring, and after long heating of dye baths at 110-140 degrees C, no dye flocculation or filtering of dye in outer yarn layers occurs.
