    摘要: New dehydrotocopherols, namely cis- and trans- 3',4'-dehydrotocopherol; cis- and trans- 4',5'-dehydrotocopherol; and 4',4'-a-dehydrotocopherol, and new didehydrotocopherols, namely cis- and trans- 3',4'-11',12'-didehydrotocopherol; cis- and trans- 4',5'-11',12'-didehydrotocopherol; and 4',4'a-11',12'-didehydrotocopherol, are useful intermediates in the preparation of Vitamin E.These intermediates are prepared by reacting trimethylhydroquinone under acid catalysis with certain C.sub.20 intermediates, namely: ##STR1## where R represnts a 3,7-dimethyloctyl or a 3,7-dimethyl-6-octenyl radical and X is halogen, hydroxyl, acetate, C.sub.1-4 alkanoate, C.sub.3-4 alkenoate, aralkenoate and benzoate.

    摘要: A process for increasing the fuel value of a gas mixture of carbon monoxide and hydrogen by converting part of the hydrogen and part of the carbon in the carbon monoxide of the gas mixture to methane, which comprises continuously introducing the gas mixture into a fluid bed in the presence of iron under conditions of pressure and temperature which promote the reduction of carbon monoxide to carbon, the formation of iron carbide from the iron and carbon, and the formation of methane and iron from iron carbide and hydrogen, and continuously removing from the fluid bed a methane enriched gas mixture including carbon monoxide and hydrogen having a substantially increased fuel value over the gas mixture introduced into the fluid bed.

    摘要: The invention relates to a process for the grafting a chain on to the 10-position carbon atom of a tricyclene skeleton, more particularly for producing 10-substituted stereospecific tricyclenes, especially cis-.alpha.-santalene and cis-.alpha.-santalol. The process involves the production of a sulphone of the tricyclene, the reaction of the sulphone with the halogenated derivative of the desired side chain and desulphonating the product.
