  • Intermediates for Vitamin A
    Patent number: 4082791
    Abstract: A synthesis of novel Vitamin A intermediates from beta-ionone is described as well as a conversion of the intermediates to Vitamin A. The length of the conjugated aliphatic side chain of beta-ionone is increased while still ultimately obtaining the desired trans form of Vitamin A. In general, beta-ionone is ethynylated to ethynyl-beta-ionol, the hydroxyl of which is etherified to form an ethynyl-terminated, alkoxy-substituted, beta-ionol intermediate. The intermediate is coupled through its copper derivative with a compound like chloro-isopentenyl acetate to produce a C.sub.20 skeleton. By semi-hydrogenation, the acetylenic bond on the C.sub.20 skeleton is converted to an ethylenic bond, and by hydrolysis the terminal ester moiety is converted to a hydroxyl group. Treatment with a strong base removes the alkoxy group to produce Vitamin A.

  • Preparation of imitation mozzarella cheese
    Patent number: 4075360
    Abstract: An imitation mozzarella type cheese for pizza pies and other products, where mozzarella cheese is used, is prepared by forming a mixture of specified amounts of a hydrogenated vegetable oil, a caseinate including at least 70% sodium caseinate, a calcium containing salt such as calcium chloride, an edible acid such as lactic acid, flavoring and color. A premix of the components, except the acid, is first prepared and thoroughly mixed at about 130.degree. to about 172.degree. F, and then the premix is directly acidified by the addition of the acid until a pH of about 6 to about 5 is reached. The product on cooling is readily formed into a desired shape, is capable of being grated, and has the properties characteristic of a mozzarella cheese.

  • Dehydrophytol
    Patent number: 4072725
    Abstract: A process for the synthesis of dehydrophytol and Vitamin E comprising forming a C.sub.15 acetylene from hexahydropseudoionone and then coupling said acetylene with 1-acetoxy-4-chloro-3-methylbut-2-ene to form a C.sub.20 acetoxy-enyne. The latter is readily subjected to partial hydrogenation and saponification in that order to form a dehydrophytol, a useful intermediate for the synthesis of Vitamin E and other products.

  • U.V. curable poly(ester-urethane) polyacrylate polymers and wet look coatings therefrom
    Patent number: 4072770
    Abstract: Polyester-urethane polymers, prepared from the reaction of specific molar ratios of diisocyanates with specific mixtures of polyesterdiols, glycols, triols and tetraols, and having 4-10 reactive isocyanate groups are further reacted with hydroxyalkyl acrylates through the free isocyanate functionality to provide oligomers having from about 4-10 acrylates units per each mole unit of polyurethane chain. Such polymers when crosslinked under ultraviolet radiation in the presence of photosensitizers, specific reactive monofunctional acrylate solvents and multifunctional acrylate cross-linking agents cure without air inhibition to yield superior "wet look" finishes especially useful for coating metal, wood and floor tile.

  • Dual cure cathodic electrocoating compositions
    Patent number: 4070258
    Abstract: An electrocoating composition containing a polymer having pendant tertiary amine groups, a polymer containing pendant mercaptan groups, an apha-, beta-ethylenically unsaturated carbonyl cross-linking agent, and a photosensitizer can be electrodeposited onto a cathode substrate disposed within an aqueous electrocoating bath. Full cure of the electrodeposited coating on the cathode substrate is obtained by the combination of heat curing and ultraviolet radiation curing. In a specific embodiment of the present invention, a single polymer contains both the pendant tertiary amine groups and pendant mercaptan groups.

  • Dual cure cathodic electrocoating composition
    Patent number: 4066523
    Abstract: An electrocoating composition containing a polymer having pendant tertiary amine groups, a polymer containing pendant mercaptan groups, a bis-maleimide cross-linking agent, and a photosensitizer can be electrodeposited onto a cathode substrate disposed within an aqueous electrocoating bath. The amine groups and the mercaptan groups are protonated with acid to render the polymers water dispersible prior to electrodeposition and are adapted to become deprotonated upon electrodeposition. Full cure of the electrodeposited coating on the cathode substrate is obtained by the combination of heat curing and ultraviolet radiation curing. In a specific embodiment of the present invention, a single polymer contains both the pendant tertiary amine groups and pendant mercaptan groups.
