Abstract: Impurities are sepd. from technical grade (at least 50%) camphor (I) by melting the (I), and then cooling to allow pure (I) to crystallise out. The crystallisation process which initially sets in and continues practically to a standstill, is set in motion against at least once by a heating step. Pref., 1-4 heating steps are employed. USE/ADVANTAGE - This method gives pure (I) without the need for solvent recrystallisation (and consequently drying), so avoids loss of both product and solvent. Pure (I) is used as a plasticiser for cellulose nitrate (in prepn. of celluloid and nitrocellulose lacquer) or cellulose propionate. It is also useful as a pharmaceutical (antiseptic or cardiac stimulant);perfume component; clothes moth repellent; in smokeless gunpowder or primers, and as fumigant. (4pp Dwg.No.0/0)

Abstract: Terpene esters are prepd. by reacting C10H16 terpenes with a lower carboxylic acid, in molar ratio of terpene:acid of 0.2-2:1, at 25-60 deg.C, on an acid ion-exchanger as catalyst. The reactants are passed upwards through a tubular reactor contg. the catalyst, at a rate such that the ion-exchanger is held in uniform suspension in the reactor.

Abstract: The invention relates to new terpene ethers of the formula in which R denotes a cyclic or bicyclic radical or an alkyl radical which is substituted by cyclic, bicyclic or tricyclic radicals, optionally via an oxygen bridge. The compounds are prepared by reaction of camphene with alcohols R-OH, in which R represents one of the above-mentioned radicals. The new ethers are used in the field of aroma substances and solvents, and as intermediates for plant protection agents, agents for combating pests and medicaments.

Abstract: 1,188,745. Purification of monochloroacetic acid. FARBWERKE HOECHST AG. 19 Sept., 1968 [19 Sept., 1967], No. 44609/68. Heading C2C. Monochloroacetic acid is purified by passing the crude acid in the liquid state at 110‹ to 145‹ C. and hydrogen over a stationary catalyst consisting of at least one noble metal of Group VIII of the Periodic Table supported on an acidresistant carrier. Specified catalysts are palladium-group metals and their alloys and specified carriers are alumina, carbon, silicic acid, silicon carbide and boron carbide.
