Patent GB-586175-A (GB)
Title: Production of sulphanilylguanidine
IPC: C07C311/64
Filed: 1944-09-05
Abstract: p-Aminobenzenesulphonylguanidine (sulphaguanidine) is obtained by heating at a fusion temperature in the range of 150-200 DEG  C., a mixture of p-aminobenzenesulphonamide or a metal salt thereof a guanidine salt of a strong inorganic acid and an inorganic alkaline agent stronger as a base at such temperature than is guanidine, until guanidine has been liberated from the guanidine salt by said alkaline agent and has fused with the p-aminobenzenesulphonamide to form p - aminobenzenesulphonyl - guanidine.  Suitable inorganic alkaline agents are sodium or potassium hydroxide, the oxides, carbonates or bicarbonates of sodium or potassium, trisodium phosphate or sodium sulphide, and, when sulphaguanidine is produced by a fusion reaction wherein the metal radical of the inorganic alkaline agent reacts with the acid radical of the guanidine salt, calcium oxide or hydroxide, or barium oxide or hydroxide.  Specified guanidine salts are guanidine hydrochloride, -nitrate, -thiocyanate or -sulphate. Reaction is effected preferably using approximately equimolecular proportions of sulphanilamide and guanidine hydrochloride, with caustic soda or sodium carbonate, and the period of heating may range from about 30 to 190 minutes.  The fusion-mass is dissolved in water, unchanged sulphanilamide and sidereaction products being removed by adding caustic alkali to the liquor at about 60 DEG  C. and the crude product crystallises out on cooling to room temperature.  The product is recrystallised from hot water, using a decolorizing-agent, e.g. animal charcoal, and the resulting crystals may be dried at 110 DEG C. for about 3 hours to convert from the monohydrate to the anhydrous state.  Examples given of the fusion of the following reaction-components to obtain sulphaguanidine: (1) sulphanilamide, guanidine hydrochloride and sodium carbonate; (2) sulphanilamide, guanidine nitrate and sodium hydroxide; (3) sodium sulphanilamide and guanidine hydrochloride; (4) calcium sulphanilamide and guanidine sulphate.

Abstract: 1291547 Cassava FEDERAL INSTITUTE OF INDUSTRIAL RESEARCH 25 May 1971 16976/71 Heading A2B Cassava roots are peeled, grated or cut to form a pulp, which may be dewatered, which is allowed to ferment, the fermented pulp is heated in a heater to produce a gelatinised mash, and the mash is dried in a dryer physically separated from the heater. Prior to the heating step, the pulp may be partly dewatered by centrifuging or pressing, and may then be milled and sieved. Fermentation may be accelerated by the addition of a suitable inoculum, such as cassava liquor or milled soya beans. Protein concentrates, vitamins, and minerals may be incorporated at a suitable point. A suitable apparatus comprises in sequence a root peeler, a cutter, a fermentation vessel, dewatering means, a heater, and a dryer. The dried product is known as gari.

Title: Alkoxylated ª-methyl glucoside
IPC: C08G18/48
Filed: 1963-04-30
Abstract: Polyurethane foams are prepared by cross-linking diisocyanate with a product of the process for the alkoxylation of a -methyl glucoside in which alkylene oxide is added to a mixture of 1 mole of a -methyl glucoside, 0.1-10 moles of a polyhydric alcohol containing at least three hydroxyl groups or an aminohydroxy compound having a functionality of at least 3, and a basic catalyst, at a temperature of 100-165 DEG  C.  The product is a co-alkoxylated product, the alkylene oxide reacting with both the a -methyl glucoside and the polyhydric alcohol or aminohydroxy compound.  In a typical example, tolylene diisocyanate was reacted with a propoxylated mixture of a -methyl glucoside and glycerol in the presence of stannous octoate, triethylene diamine and trifluorochloromethane to produce a polyurethane foam.ALSO:In a process for the alkoxylation of a -methyl glucoside an alkylene oxide is added to a mixture of 1 mole a -methyl glucoside, 0.1-10 moles of a polyhydric alcohol containing at least 3 hydroxyl groups, or an aminohydroxy compound having a functionality of at least 3, and a basic catalyst, at a temperature of 100-165 DEG C.  The basic catalyst, generally used in an amount of 1-5% by weight of polyol, is preferably an alkali metal hydroxide or alkoxide, or a tertiary amine.  Polyhydric alcohols can be aromatic or aliphatic, preferred being glycerol, pentaerythritol and polypentaerythritol. If excess polyol is used, this acts as solvent for a -methyl glycoside, Suitable aminohydroxy compounds are mono-, di-, or tri-ethanolamine. The examples indicate the use of propylene oxide as alkoxylating agent.  The mixture obtained is neutralized with a mineral acid. This mixture is the product.  The product is a coalkoxylated product, the alkylene oxide reacts with both the a -methyl glucoside and the polyhydric alcohol or amino hydroxy compound. The products may be readily cross-linked with di-isocyanates to form polyurethane foams (see Division C3).

A laminated belt having a core of textile fabric and outer covers of a substantially impervious material is manufactured by a method in which after the several laming have been assembled and heat-treated, one or both such outer covers is or are provided with a plurality of small holes or apertures extending through it or them and distributed over the surface of the belt, after which water is allowed to have access to the said fabric core through such openings and be taken up thereby, to replace moisture expelled during said heat treatment. The water taken up may be derived from the atmosphere by simple exposure thereto, or from passing the belt through a bath of water, or from swabbing, swilling or spraying the belt with water or from steaming of the belt or from any combination of these. The openings may be provided by passing the belt under or over a spiked roller or by the use of a reciprocating spiked plate or bar. The cover layers may be of rubber or of polyvinyl chloride, and may be perforated, while still warm and not fully set, or after they have become set and cold. The fabric layers may be of cotton or of mixed natural and man-made fibres, and may be embedded in a matrix of polyvinyl chloride or similar thermoplastic material. The moisture content of the fabric; which is reduced in the laminating process, may be rapidly restored by the process of the invention. The surface of the belt may be provided with ribs or the like, which may be made by the roller that forms the holes. The holes may be arianged to form a pattern or Trade Mark. According to the Provisional Specification, the covers may be perforated during their formation.
