Abstract: Diketones are prepared by oxidizing glycols in the presence of a silver catalyst and/or copper catalyst of a specific particle size, under specific temperature conditions and with a specific composition of the catalyst. The end products are starting materials for the preparation of dyes, drugs, plastics, scents, wrinkle-resist finishes and assistants for increasing the tear strength and resilience of fibrous materials, hardeners for use in the photographic industry, textile assistants for preventing shrinkage after washing, and paper assistants.

Abstract: Polyisocyanates are prepd. by (a) condensing aniline and aq. HCHO in the presence of HCl and distilling the reaction mixt. without neutralisation to separate (and opt. recycle) water and/or unreacted aniline, (b) converting the polyamine-polyamine hydrochloride mixt. entirely to hydrochloride by suspending it in liq. HCl and adding liq. COCl2 to convert the hydrochloride to isocyanate. Pref. the mole ratio aniline:HCl is 15-160:1. Prods. are esp. used for prodn. of wood glues. The process is simple, non-polluting and free from waste.

Abstract: 1480921 Stabilizing aqueous formaldehyde BASF AG 25 Nov 1974 [26 Nov 1973] 50896/74 Heading C2C Aqueous formaldehyde solutions are stabilized by means of a bis-guanamine of formula wherein the two substituent on the phenylene ring are in m or p-position to each other. 0À001 to 0À5% by weight of stabilizer may be used and the formaldehyde solution may contain 28-65% by weight of formaldehyde. The stabilizer may be added as a stock solution in a formaldehyde solution of higher strength than that to be stabilized and having a pH of 2À5 to 5À8 and the latter is preferably kept at 40-80‹ C. for 10-30 hours before adding the stock solution.
