Title: Production of omega hydroxy decanoic acid and other oganic compounds
IPC: C07C55/20
Filed: 1940-01-26
Abstract: 534,321. #-Hydroxy decanoic acid. AMERICAN CYANAMID CO. Jan. 26, 1940, No. 1640. Convention date, Feb. 8, 1939. [Class 2 (iii)] #-Hydroxy decanoic acid is produced by reacting ricinoleic acid or a ricinoleate such as castor oil or ricinoleic amides with caustic alkali solution maintained at 150-300C., preferably 190-205C. The ricinoleate is added at a rate such that excessive foaming does not occur. Capryl alcohol and methyl hexyl ketone are produced as volatile bye-products. The reaction product is slightly acidified to separate unchanged oil, and the aqueous layer is strongly acidified to separate the #-hydroxy decanoic acid. Foaming is reduced by adding the ricinoleate slowly or by adding a highboiling hydrocarbon oil. The yield of methyl hexyl ketone may be increased by returning the oily layer of the condensate of the volatile bye-products to the reaction chamber, and the yield of capryl alcohol by adding a small quantity of a calcium salt. Ricinoleate from a supply 8 is passed into a reaction chamber 1 containing the alkali solution, through a pipe 9 containing a sight glass 17, volatile products passing off through a pipe 14 containing a sight glass 15 to a condenser 16 and separator 21. The oily layer from the separator 21 may be returned to the reaction chamber by a pipe 29 or drawn off at 32 to be treated with a bisulphite for the recovery of the ketone. A part of the aqueous layer from the separator is returned to the reaction chamber by a pipe 25 containing a valve 30 operated by a thermostat 40. The feed of ricinoleate to the reaction chamber is regulated so that no foam is visible in the sight glass 15. The non-volatile reaction product is slightly acidified to separate unchanged oil, and the aqueous part strongly acidified to separate #-hydroxy decanoic acid. If the reaction temperature exceeds 205 C. some sebacic acid is also formed. It may be separated from the hydroxy decanoic acid by extraction with hot water, or precipitating the mixed di-alkali salts with alcohol in which the hydroxy decanoic:acid salt is insoluble.

Abstract: 551,268. Automatic control systems. FOXBORO CO. Feb. 13, 1942, No. 1973. Convention date, March 6, 1941. [Class 38 (iv)] [Also in Group XX] Apparatus for indicating the relative humidity of an atmosphere comprises means for maintaining the temperature of a tubular member at a value corresponding with the value of the absolute humidity of the atmosphere, a first temperature responsive means responsive to the temperature of the tubular member, a second temperature responsive means separate from the tubular member and movably reponsive to the temperature of the atmosphere means connecting the two temperature-reponsive means in opposed relationship and means responsive to the net movement of the temperature-responsive means, the first temperature-responsive means being located inside the tubular member and being freely movable to position corresponding to the temperature of the tubular member. As shown, the humidity-responsive element 2 comprises a layer of paper 5 impregnated with lithium chloride and wrapped around a silver tube 4. A conducting wire 6 is wound helically upon the impregnated paper. The tube 4 and wire 6 are connected to the secondary of a transformer 9 so that the energy supplied passes through and heats the impregnated paper and owing to the variation of resistance of the lithium salt with change of temperature and moisture content maintains the lithium salt in moisture equilibrium with the surrounding atmosphere. The resulting equilibrium temperature of the element 2 is measured by a bimetallic helix 15 within the tube 4 connected to a second oppositely-wound bimetallic helix 17 which responds to the variations in the atmospheric temperature. The differential movements of the two helices are transmitted by a shaft 18 to a rotatable card 21 marked with an oblique line read in terms of relative humidity against graduations on the case 1. When it is desired to control the humidity of a room or other space a contact disc 32 on the shaft 18 is arranged in circuit with a transformer 38 so as to control a relay 40 which opens and closes a solenoid valve 26 in the water pipe 25 of a suitable humidifying unit in order to maintain a constant humidity..
