Abstract: The invention comprises compounds of the formula <FORM:0754162/IV(a)/1> where n is 3 or 4 and R is an alkyl group of 1-4 carbon atoms and their preparation by treating a cyclobutyl alkyl ketone or a cyclopentyl alkyl ketone with sodium acetylide in liquid ammonia. In examples (1) acetylene is passed into liquid ammonia to which metallic sodium is added and the resulting solution of sodium acetylide is treated with cyclobutylmethylketone to give 1-cyclobutyl-1-ethynyl-ethanol which extracted with ether and separated by fractional distillation; and (2) cyclopentylmethylketone is treated with sodium acetylide as in (1) to give 1-cyclopentyl-1-ethynyl ethanol.ALSO:Pharmaceutical preparations having hypnotic activity comprise compound of the general formula <FORM:0754162/VI/1> where n is 3 or 4 and R is an alkyl group of 1 to 4 carbon atoms (see Group IV(b)) in admixture with a non-toxic carrier.  The carrier may be a liquid capable of giving solutions, elixirs or emulsions or a solid absorbent such as diatomaceous earth or magnesium oxide, capable of being pressed into tablets.  The carbinols may also be incorporated with peanut oil, sesame oil, corn oil or other edible oils and enclosed in capsules.

Title: Manufacture of polysiloxane condensation products
IPC: C08G77/00
Filed: 1952-06-06
Abstract: A condensation product, suitable for lacquers, impregnating agents or mouldings, is made by reacting an organopolysiloxane containing -SiH groups with a polyhydric alcohol or a partially esterified or etherified polyhydric alcohol or a mixture thereof, preferably in the presence of a catalyst and at a raised temperature.  There may be added and reacted at any desired stage an aliphatic or aromatic polycarboxylic acid, or anhydride thereof, e.g. phthalic acid or anhydride and maleic acid, a fatty oil, e.g. castor, wood or tall oil, a saturated or unsaturated fatty acid of at least 12 carbon atoms, e.g. oleic acid, a high molecular weight hydroxy carboxylic acid, e.g. ricinoleic acid, a resin acid, e.g. abietic and pimaric acids, a synthetic resin modified with any of the aforementioned compounds, a trialkylalkoxysilane or a trialkylsilanol, e.g. trimethyl-ethoxy silane or trimethyl-silanol.  Additives such as driers, softening agents, stabilizers and synthetic resins modified in known manner by esterification or etherification may also be added at any desired stage.  Catalysts specified are caustic soda and potash and alcoholates, acids and aluminium acetyl-acetonate.  In examples the polysiloxane obtained by cohydrolysing dimethyldichloro-and methyldichloro-silanes is reacted with (1) oleic monoglyceride, (2) glycerine and oleic acid, and (3) pentaerythrite and oleic acid; (4) the product of Example (3) is further reacted with phthalic anhydride.
Patent GB-583268-A (GB)
Title: Improvements in or relating to alkyd resins
IPC: C08G63/60
Filed: 1944-07-28
Abstract: Fast-drying resinous products are prepared by heating together glycerol phthalic anhydride, hydroxyacetic acid and linseed oil or linseed oil fatty acids in such proportions that the product contains when expressed in terms of those ingredients 30-70 per cent of linseed oil and a weight ratio of polyhydroxyacetic acid to glyceryl phthalate below 0.7 and not below 0.1.  Modifying agents which may be used in addition to linseed oil are soya, chinawood, cottonseed, oiticica, perilla, castor, dehydrated castor, coconut, sunflower seed or corn oil or the fatty acids from these oils, butyric, stearic, acrylic, furacrylic, oleic, p  lactic, chloracetic, benzoic, salicylic or rosin acid, or butyl, n-dodecyl, benzyl, or cyclohexyl alcohol.  Excess glycol may be used to increase drying rates.  The reactants may be mixed in any suitable order.  Fatty oils should be heated with all or part of the polyhydric alcohol before addition of the acid components. The hydroxyacetic acid may be used as a water solution.  The preferred temperature range is 150-250 DEG  C. Various catalysts, e.g. litharge, sodium hydroxide or acids may be employed. Certain acid salts, e.g. monosodium phosphate improve the colour of the resins.  The reaction may be performed in solution, e.g. in a hydrocarbon or in the absence of solvent.  The resins are useful as vehicles for air drying or baking compositions which may also include pigments, metallic driers, dyes, fillers, waxes, inhibitors, plasticisers or thinners, and other film-forming ingredients, e.g. cellulose derivatives, rubber derivatives, urea-formaldehyde resins, phenol-formaldehyde resins, other alkyd resins, rosin, ester gum, limed rosin, polymethyl methacrylate, polystyrene, or polyvinyl acetate.  The resins can also be used as adhesives or moulding compositions or as grinding vehicles or in the incorporation of hydrophyllic extenders in pigment formulations. Examples describe (1) preparation of a resin from linseed oil acids, glycerol, phthalic anhydride, and hydroxyacetic acid by heating in an atmosphere of carbon dioxide with addition of toluene and removal of water and some toluene.  The product is dissolved in a mixture of low-flash naphtha and mineral spirits. Incorporation of cobalt, lead or manganese naphthenate gave a solution which was air dried tack-free in 5-7 hours and gave tough films after baking for two hours at 140 DEG  C.  (2) Similar to (1), the linseed oil acids and glycerol being reacted before addition of the other ingredients and hi-flash naphtha being the reaction medium.  Four other examples describe similar preparations with differences of detail.  Example (4) describes the blending of the hydrocarbon solution of resin with a standard toluidine red mill base and preparation of films from the mixture. Comparative figures are given for the drying rates of resins prepared according to the invention and prepared from mixtures of the same reaction ingredients in different proportions.

Abstract: 1,260,995. Fermentation production of L- threonine. AJINOMOTO CO. Inc. 25 March, 1970 [28 March, 1969], No. 14493/70. Heading C2C. L-Threonine is produced by culturing an L- threonine producing microorganism in a nutrient medium containing acetate ions as a primary assimilable carbon source and an assimilable nitrogen source under aerobic conditions. The acetate ions may be provided by acetic acid or its K, Na, NH 4  or Ca salt. Suitable nitrogen sources are urea, ammonia and ammonium salts, e.g. chloride, sulphate or carbonate. Ammonium acetate may serve as the source of both C and N. The medium should also contain inor-  ganic ions and organic growth-promoting substances such as Vitamin B1, biotin, yeast extract, corn steep liquor, soybean protein hydrolysate, fish meal, digested fish meal and casein hydrolysate. The preferred conditions are: (1) intermittent or continuous addition of the acetate and ammonium ions; (2) concentration of acetate ions kept below 1À5% by weight; (3) pH maintained at 7À0 to 8À5. Carbohydrates may be added as a secondary carbon source in amounts less than that of the acetate ions. Specified microorganisms are mutant strains of Brevibacterium flavum and Corynebacterium acetoacidophilum and also of Micrococcus, Microbacterium and Arthrobacter.

Abstract: <PICT:0753070/III/1> In the plant shown for recovering sodium carbonate and sodium sulphide from the digestor residual liquor-black liquor-emanating from pulp mills utilizing the so-called "soda" and "kraft" processes the liquor, delivered into the water cooled chamber 10 by an oscillatably mounted nozzle 22 is subjected to the heat of the gases rising from the char bed on the inclined hearth 15.  A fan 27 delivers air from a heater 28 in the gas flow path through damper-controlled ducts 54 and a horizontal duct 56 to a primary air conduit 57 encircling the chamber and connecting with damper-controlled primary air ports 29.  A pair of secondary air damper-controlled conduits 58 connect the heater to damper-controlled secondary air ports 30 arranged in the rear and side walls of the chamber.  The combustion gases from the chamber pass successively over a water tube screen 21, superheater 34, generating tube banks 35, 36, economizer 33 and air heater 28 before passing through a Venturi type gas and liquid scrubber 43 and a cyclone separator 45. Some of the cleaned gases are returned to the furnace chamber being withdrawn for this purpose from the gas flow path by a fan 70 through a pipe 71 and discharged through a duct 72 fitted with a control damper 73 to the supply duct 56 for the primary air ports.  Automatic regulation of the damper 73 in response to changes in the indication of an optical pyrometer pointed at the char bed can be readily effected.  The chemicals are discharged, in a molten state, from the hearth 15 into a dissolving tank 17 through a spout 16.  Additional chemicals are recovered from the combustion gases in the scrubber 43 the black liquor separated in the separator 45 being used as the wash liquor in the scrubber.
