Abstract: 2-(1-Hydroxycarbalkoxymethyl)-acrylonitriles and 2-(1-hydroxycarbalkoxymethyl)-acrylates are prepared by a process in which an acrylonitrile or an acrylate is reacted with a glyoxylate in an aqueous medium at a pH greater than or equal to 6, in the presence of a tertiary amine as a catalyst.

Abstract: The invention relates to basic chromium aluminum sulfates which are soluble in cold water and are of the general formula CrxAl2-x(OH)2y. (SO4)3-y.n H2O where x is from 0.1 to 1.9, y is from 0.01 to 2 and n is from 4 to 24, and a process for the preparation thereof. The process comprises reacting chromium (III)-containing waste sulfuric acid having a water content of 20-50% by weight with aluminum oxide and/or aluminum oxide hydroxide and/or aluminum hydroxide at a temperature of 100 DEG to 200 DEG C. The molten product is converted to droplet form and allowed to solidify in free fall.

Abstract: Conventionally limed hides are delimed for from one to six hours under conventional deliming conditions in respect of liquor length, temperature and pH of the liquor, by a process in which a cyclic carbonate of a polyhydric aliphatic alcohol of 2 to 6 carbon atoms is employed as the active agent.

Abstract: An auxiliary for the soaking of hides and skins, which consists of a salt of the formula I M+[O3S-S-R]- I where R is an organic radical of 1 to 8 carbon atoms, which may carry one or more functional groups, and M+ is one equivalent of a cation, mixtures thereof with other conventional soaking auxiliaries, and processes for their use. Using the novel auxiliary avoids all toxicity hazards and odor nuisance, as well as avoiding oxidation losses, and achieves good loosening of the hair.
