    Abstract: 1300166 Granular Vitamin A esters BADISCHE ANILIN- & SODA-FABRIK AG 24 April 1970 19802/70 Heading C2V Granular Vitamin A esters are prepared by dripping molten Vitamin A ester into an organic liquid at -10 to -70‹ C., the liquid being one in which the ester is insoluble and which has a lower density than the esters, the resultant granules then being separated and dried. The liquid may be an alcohol or a gasoline. An antioxidant may be added to the melt. In examples, molten Vitamin A acetate and Vitamin A palmitate are dripped into cooled methanol to form granules.

    Abstract: 1,168,639. Double bond synthesis. BADISCHE ANILIN- & SODA-FABRIK A.G. 16 Dec., 1966 [18 Dec., 1965], No. 56427/66. Heading C5E. [Also in Division C2] Compounds containing an olefinic double bond are prepared by continuously contacting a phosphorus ylid with a carbonyl compound in a substantially constant molar ratio and continuously removing the reaction mixture containing the product from the reaction zone. Alternatively a phosphonium salt which yields the phosphorus ylid on reaction with a proton acceptor, may be continuously contacted with a proton acceptor and a carbonyl compound and the reaction mixture removed as before. The reactants are preferably cooled and supplied in liquid or dissolved form, and may be contacted in a mixing nozzle, stirred reactor or a circular tube system. Compounds of the Formula (VII) are formed from the ylid (III) and the carbonyl compound (V) Examples of suitable carbonyl compounds are 2-methyl-2-butenal, #-ionone, citral, 2-methylhept-2-en-one #-ionylidene acetaldehyde and Vitamin A aldehyde. The groups R 1 and R 11 may be C 1 -C 30 saturated or unsaturated aliphatic radicals.
