Patent GB-800706-A (GB)
Title: Liquid detergent compositions
IPC: C11D3/12
Filed: 1956-08-03
Abstract: A liquid detergent composition comprises an organic synthetic detergent and a water-soluble inorganic alkaline builder salt and a minor proportion of a substantially water-insoluble wax or wax-like substance in an aqueous alcoholic medium, the inorganic builder being present in an amount in excess of its normal solubility in the amount of liquid present, the excess constituting a permanent non-caking suspension in the liquid.  The detergent, which is present in amounts of 5-30 per cent, may be either anionic, such as the sulphate esters of polyhydric alcohols incompletely esterified with higher fatty acids, the higher fatty esters of low molecular weight alkylol sulphonic acids, the higher fatty acid ethanolamide sulphates, and the higher fatty acid amides of amino-alkylsulphonic acids, or non-ionic, such as ethylene oxide condensates with higher fatty acid alkanolamides, with higher fatty alcohols or acids, with tall oil acids, with higher allyl mercaptans, amides, or polypropylene glycols.  The preferred detergents, however, are the higher alkylaryl sulphonates such as dodecylbenzene sulphonate, or the higher alkyl sulphates such as lauryl sulphate, where the detergent is present as the sodium, potassium, ammonium, isopropanolamine or mono or tri-ethanolamine salt and contains 8-15 carbon atoms in the alkyl group, or the condensation product of 8-30 mols. of ethylene oxide with 1 mol. of a higher alkyl phenol.  The preferred builder salts, which are present in amounts of 15-45 per cent, are the sodium and potassium condensed phosphates, but soda ash and borax may also be used.  Wax-like substances which may be used are hydrogenated castor oil, fatty acids, alcohols and amides having more than 18 carbon atoms, natural waxes such as carnauba, candelilla, montan and beeswax, ozokerite and ceresin, or synthetic wax-like substances such as esters of higher fatty acid alkanolamides, and are usually incorporated in amounts of 0.1-1.0 per cent.  The composition generally also includes 0.1-10 per cent of either an inorganic colloidal siliceous material such as aluminium-magnesium silica gel ("Veegum"), bentonite, or magnesium silicate, or a polyvalent metal soap such as a calcium, magnesium or zinc soap.  The compositions have thixotropic properties, and to ensure this 2-20 per cent of urea or thiourea is normally included.  The compositions usually contain 5-20 per cent both of water and of a saturated lower aliphatic alcohol such as ethanol, propanol and isopropanol, and also 0.25-5 per cent of a soil anti-redeposition agent such as a cellulose ether, particularly sodium carboxymethyl cellulose.  The total solids content is 60-90 per cent.  Perfumes, colouring material, corrosion and tarnish inhibitors, germicides, hydrotropes, bleaching agents and optical bleaches may also be incorporated.

Patent GB-716330-A (GB)
Title: Improvements in the purification of cellulose
Inventor: BATE STANLEY CHARLES
IPC: D21C9/08
Filed: 1951-10-17
Abstract: Crude cellulose, obtained from lignocellulosic material by an alkaline pulping process, is purified by heating it with an aqueous solution of an inorganic sulphite or bisulphite with or without free sulphur dioxide, then bleaching it, and then removing pentosans from the bleached cellulose by means of an aqueous solution of an alkali of concentration above 8 per cent.  The crude cellulose pulp may be heated with the sulphite solution under pressure at a temperature above 100 DEG C., e.g. between 125 DEG  and 150 DEG C.  A sulphite or bisulphite of ammonia, an alkali metal, alkaline-earth metal or magnesium may be used, preferably in a concentration below 2 per cent.  The solution may contain a small proportion, preferably not more than 0.25 per cent., of free sulphur dioxide.  The sulphite boil may be followed immediately by treatment with an alkali, e.g. a caustic alkali solution of concentration below 3 per cent. at 100 DEG C. or higher.  The bleaching may be effected in two or more stages, any or all of which may be under acid or neutral conditions, e.g. a two-stage bleach with a neutral hypochlorite solution or a three-stage bleach with hypochlorite in which the first two stages are effected under acid conditions and the final stage under neutral conditions.  Each bleaching stage may be followed by a treatment with alkali, e.g. caustic soda of concentration below 2 per cent. at 60-100 DEG C.  The bleached cellulose may be treated with caustic alkali of concentration 10-20 per cent. at 20-25 DEG c., or of concentration 17-19 per cent. at 40-60 DEG C. for 45-90 minutes, and may then be boiled under atmospheric or higher pressure with a 0.25-2 per cent. caustic soda solution.  The purified cellulose may be given a final very weak bleach with acid, neutral or alkaline hypochlorite. The purified cellulose obtained may be used for the production of cellulose esters and ethers.

Abstract: 367,812. Oil gas and water gas generation. JONES, L. B., 58, Sutter Street, San Francisco, U.S.A. Aug. 15, 1930, No. 24543. [Class 55 (i).] In the production of oil gas in admixture with water gas, oil is cracked in a checkerwork chamber previously heated by combustion of the " blow gas " from a fuel bed, and the gas is filtered through a fuel bed which has previously been cooled to below the cracking temperature by steaming. In the first half of a cycle, the " blow " gases from a fuel bed 28 pass to the cracking chambers 16, 15, and after combustion therein escape by a damper 20 ; secondary air is admitted at 24. The fuel bed is now steamed, and simultaneously oil is injected into the chamber 16 through a valve 22<1> and the oil gas formed mixes with the " run " gases from the fuel bed, and the mixture with entrained carbon passes into the fuel bed 27, which has been steamed during the previous "run" ; its temperature may be from 1200‹ to 1500‹ F. The second half of the cycle is carried out in the reverse direction, the fuel bed 27 being blasted and steamed and the fuel bed 28 being already cooled below the cracking temperature. In a modified system of working the apparatus is combined with a tar scrubber, from which tar, condensed from the oil gas, is pumped to the fuel chamber which at the instant is acting as the filter bed.
