    Abstract: PCT No. PCT/EP95/02592 Sec. 371 Date Mar. 20, 1997 Sec. 102(e) Date Mar. 20, 1997 PCT Filed Jul. 4, 1995 PCT Pub. No. WO96/01242 PCT Pub. Date Jan. 18, 1996A process is disclosed for the selective hydrogenation of butynediol to 2-butene-1,4-diol using a palladium catalyst to which either copper and zinc, or silver and zinc, or copper, silver and zinc are added as doping agents. In the preferred embodiment, it has been possible, by optimizing the composition of the catalyst, to improve the activity and selectivity of the catalysts in question while also eliminating the need to handle toxic substances during the catalyst manufacturing process.

    Abstract: Aqueous solutions of glyoxal which contain acids are purified by treatment with a solution which contains from 20 to 60% by weight of a tertiary amine and from 80 to 40% by weight of an alcohol which is not infinitely miscible with water, the treatment being carried out by mixing the two solutions during a residence time of less than 5 minutes.

    Abstract: 834,757. Paper &c. containing porous substances. BADISCHE ANILIN- & SODAFABRIK A.G. July 18, 1958 [July 27, 1957], No. 23073/58. Class 96. Paper, e.g. for filtering, shoe linings, bactericidal use, sound insulation, or multiple-ply cardboard &c. which may be 50% less dense than usual cardboards, is formedfrom, e.g. sulphite or sulphate wood pulp, e.g. with up to 85% of mechanical wood pulp, or from esparto, straw, grasses, linen rags, or waste paper &c. by adding to the pulp, e.g. 5 to 80% of the paper of a porous, hardened condensation product, e.g. of phenol-, or urea-formaldehyde, or such products made from mono- or polymethyl-, propyl-, or butyl-phenols, or thiourea or biuret, or triazines, e.g. melamine, dicyandiamide or guanamide, &c. The foaming of the condensation product may be effected by nitrogen, oxygen, air, carbon dioxide, ammonia, or hydrogen sulphide, in the presence of an anionic wetting agent, and of a protective colloid, e.g. polyacrylic acid salts or casein, and of acidic hardening agents, softeners, &c. The paper pulp or the resin foam may be pigmented and fillers, e.g. china clay, satin white, blanc fixe, titanium white, metal powders, oxides or salts, may be included. The porous condensation products reduce the combustibility of the paper, and small amounts not taken up clarify the white water.
