Abstract: In the catalytic hydrogenation of fatty acid methyl ester mixtures, the mixtures are continuously reacted with hydrogen under pressures of from 100 to 300 bar and at temperatures of from 160.degree. to 270.degree. C. with molar ratios or hydrogen to fatty acid methyl ester mixture of from 10:1 to 500:1. The reaction is carried out over catalysts which contain from 30 to 40% by weight copper, from 23 to 30% by weight chromium, from 1 to 10% by weight manganese, from 1 to 10% by weight silicon and from 1 to 7% by weight barium (% by weight, based in each case on total weight of the oxidic catalyst) and, if desired, other transition metals in the form of their oxides. After calcination of the components, the catalyst is converted into shaped particulate and/or granulated elements with from 1 to 10% by weight, based on oxidic catalyst, of at least one binder in addition to 1 to 10% by weight graphite. The catalyst is activated with hydrogen or a hydrogen-containing gas mixture.

Abstract: A process and liquid composition for cleaning, restoring and polishing a hard, porous surface wherein the composition contains from 0.1 to 4 weight percent of a surfactant, from 5 to 20 weight percent of a synthetic hydrocarbon oil, and from 76 to 94.9 weight percent of a C.sub.1 -C.sub.4 aliphatic alcohol. The composition may be applied to a variety of work surfaces such as work benches and kitchen counters, particularly porous surfaces such as slate, wood, vinyl, tile and rubber, wiped thereon and the surface allowed to dry.
Abstract: 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.

Abstract: Prior art processes for removal of one or more contaminant elements, including at least one of antimony, bismuth, and arsenic and optionally including iron, from electrolyte solutions of primary metals by solvent extraction with an organic phase including a hydroxamic acid, then precipitating at least part of the contaminant elements from the organic phase as sulfides, are improved by an additional step of re-extracting the organic phase with water before precipitating the sulfides from it. At least part of any arsenic present and, if desired, part of any antimony as well, may be re-extracted in this manner and subsequently recovered if desired, so that the overall process is made more economical.
