Patent GB-912104-A (GB)
Title: Manufacture of glycidyl esters
IPC: C07D303/16
Filed: 1961-02-23
Abstract: A glycidyl ester of a carboxylic acid is made by heating a 10 to 20-fold excess of epichlorohydrin and an aqueous solution of an alkali metal salt of a carboxylic acid, containing not more than 18 carbon atoms per carboxylic group, in the presence of a quaternary ammonium halide until substantially all the salt has reacted, and recovering the glycidyl ester.  Glycidyl pelargonate is a novel compound.  The alkali metal salt may be the potassium or sodium salt of a mono- or poly-carboxylic acid.  The quaternary ammonium halide may be a tetraalkylammonium halide or an arylalkylammonium halide. Specified acids whose salts may be used are acrylic, stearic, pelargonic, azelaic, sebacic, adipic, succinic, phthalic, and oleic acids, dimerized linoleic acid and trimerized linoleic acid.  The reaction is preferably effected in a vessel equipped for distillation and water in the aqueous solution added distilled of continuously with epichlorohydrin, the distillate is condensed, and the epichlorohydrin separated and returned to the reaction vessel, until the reaction mixture becomes substantially anhydrous.  The glycidyl ester is obtained by crystallisation or by distilling of excess epichlorohydrin under reduced pressure.  The glycidyl ester may be purified by dissolving in an inert organic solvent of low polarity, such as benzene or hexane, adding to the solution 1 to 20% of magnesium silicate, stirring the resulting mixture for at least about one hour, filtering the mixture to remove magnesium silicate and adsorbed impurities and removing the solvent from the glycidyl ester.

Abstract: 1,139,973. Flash operation. EASTMAN KODAK CO. Feb.17, 1966 [Feb.23, 1965], No.6951/66. Heading G2A. In a camera having a shutter of the singlebladed hammer-operated type, the action of the hammer both actuates the shutter and fires the flash bulb. As shown, the shutter is a blade 28, normally spring-biased into the position shown, in which it covers the exposure aperture 12. The shutter release is a lever 19, pivoted on a pin 20, and having a lug 27 behind which latches a finger 26 of a shutter-striking hammer or plate 23. The plate 23 is spring-loaded so that it would pivot on pin 24 to strike the shutter if it were not restrained by lug 27. The lamp 18 and batteries 33 are in series with switch elements 34, 35, these normally being out of contact owing to the resilience of the curved end of element 35. A control cam 36 pivots independently on a pin secured to the camera housing, and has an ear 38 which is laterally aligned with lug 27 and is also in the path of finger 26. When the trigger button 15 is pressed, lever 19 pivots downwards, so that lug 27 swings out of engagement with finger 26. Plate 23 pivots rapidly under the action of spring 25, the finger 26 first striking ear 38. The cam(36) pivots on its pin (37) Fig.4 (not shown), and its curved end engages the flexible end of switch element 35 and brings it into contact with element 34, Fig.4 (not shown) and Fig.2, so closing the circuit to fire the flash bulb 18. The finger 26 continues its movement to strike an ear 32 of the shutter 28, so causing the shutter to swing on its pivot and so uncover the exposure aperture. If the bulb has a delayed peak illumination, this will be produced just when the aperture is fully open.
