    Abstract: 1,153,548. Unsaturated tetrasilicates. BADISCHE ANILIN- & SODA-FABRIK A.G. 14 Sept., 1967 [15 Sept., 1966], No. 41974/67. Heading C3S. [Also in Divisions C5 and D1] The invention comprises tetrasilicic acid esters of long chain unsaturated fatty alcohols or of mixtures thereof with long chain saturated fatty alcohols which mixtures have iodine numbers of at least 40, the alcohols being unblown. By " long chain " is meant at least 12 carbon atoms. The esters may be prepared by the conventional reaction of silicon tetrachloride with the alcohols at elevated temperature. Examples of unsaturated alcohols are n-hexadecenyl, oleyl, elaidyl, eicosenyl, linoleyl and linolenyl alcohols. Examples of saturated alcohols are lauryl, n-tridecyl, myristyl, cetyl, n.heptadecyl, stearyl and arachidyl alcohols. The compounds are used as textile-treating agents (see Divisions C5 and D1).

    Abstract: 1,221,849. Fire-proofing. BADISCHE ANILIN-& SODA-FABRIK A.G. 1 July, 1968 [5 July, 1967], No. 31242/68. Heading D1P [Also in Division C2] Cellulosic fibrous materials are given a washresistant fireproof finish by applying thereto a composition consisting of a mixture of phosphoric amides having the general formula: wherein a is from 0.1 to 2.6, b is from 0.3 to 2.0 and c is from 0.1 to 1.0, the total of a b and c being 3.0. The flameproofing agent is generally used in a 5 to 50% by weight aqueous solution, the amount being such that the fibrous material absorbs from 5 to 50% by weight (with reference to the dry weight of the fibrous material) of the mixture of phosphoric amides. Application of the fireproofing agent to the fibrous material may be by dipping, spraying or padding. After the impregnated fibrous material has been dried, the agent is fixed thereon by. heating for two to twenty minutes at 100 to 200‹C. Following this, any un-fixed agent is removed e.g. by washing with hot dilute aqueous alkali-metal hydroxide solution or alkali metal carbonate solution. Cellulosic fibrous materials mentioned are cotton, linen, sisal, hemp, regenerated cellulose and wood-wool in the form of filaments, threads, fibres, wadding, non-woven fabrics or sheet materials such as textiles and papers. These materials may be mixed with others e.g. wool, silk, polyester, polyamide or polyacrylonitrile. The fireproofing agent may be used in admixture with other textile finishing agents e.g. aminoplast-forming monomeric, oligomeric and polymeric compounds.

    Abstract: A mixture suitable for use as a fertilizer, having a low content of nitrogen capable of being split off by urease and containing crotonylidene diurea and other urea-acetaldehyde condensation products, is prepared by reacting urea with acetaldehyde in the molar ratio of 1 : 1.01-1.5 in an aqueous solution at elevated temperature at a pH of less than 3 at least at the end of the reaction, adjusting to pH 5-9 after the reaction, and drying the resulting solids with all or part of the liquid present (see Division C2).ALSO:A mixture comprising crude crotonylidene diurea (4 - methyl - 6 - ureido hexahydropyrimidine-2-one) is obtained by reacting urea and acetaldehyde in a molar ratio of 1 : 1.01-1.5 in an aqueous solution at elevated temperature at a pH of less than 3 at least at the end of the reaction, adjusting to pH 5-9 after the reaction, and drying the resulting solids with all or part of the liquid present. Acids which may be used during the reaction include HCl, H2SO4, HNO3 and p-toluenesulphonic acid; preferred reaction temperatures are 30-100 DEG C. Examples use KOH solution for final pH adjustment. The product is of use as a fertilizer (see Division C1)
