摘要： A catalyst composition comprising copper oxide, zinc oxide and zirconium oxide, the content of zirconium oxide being 30 to 70% by weight. This catalyst composition is useful for synthesis of methanol from carbon monoxide and/or carbon dioxide and hydrogen by a gasliquid-solid phase fluidized bed method or a gas-solid phase fluidized bed method.

摘要： An improved composition for use in the production of composite carbon materials comprises a mesophase pitch containing at least 80% of an optical anisotropic phase and having a softening point of no higher than 250 DEG C, and sulfur present in an amount of 6 - 35 parts by weight per 100 parts by weight of said mesophase pitch. Said composition may be heated together with an aggregate and subsequently shaped to yield a composite carbon material. The improved process for producing a composite carbon material comprises impregnating an aggregate with said composition as it is melted, shaping the mixture in a temperature range of 150 - 350 DEG C, and then carbonizing the shaped part.

摘要： An object of the present invention is to provide a process for producing high purity tricycloÄ5. 2. 1. 0 Üdecane-2-carboxylic acid ester which has a small content of an unsaturated compound and which has an excellent fragrance and is useful as a perfume or a perfume component. In a process for producing tricycleÄ5. 2. 1. 0 Üdecane-2-carboxylic acid ester by reacting tricycleÄ5. 2. 1. 0 Üdeca-3-ene with carbon monoxide and alcohol in the presence of HF, carried out separately are (a) a step in which tricycleÄ5. 2. 1. 0 Üdeca-3-ene is reacted with carbon monoxide to produce acyl fluoride and (b) a step in which acyl fluoride obtained in the step described above is reacted with alcohol to produce an ester, whereby tricycloÄ5. 2. 1. 0 Üdecane-2-carboxylic acid ester having a small content of an unsaturated compound can be obtained at a high yield. Also, the reaction conditions at the step (a) described above are selected or a step for carrying out isomerization reaction of tricycloÄ5. 2. 1. 0 Üdecane-2-carboxylic fluoride obtained at the step (a) is interposed between the step (a) and the step (b), whereby capable of being efficiently produced is tricycleÄ5. 2. 1. 0 Üdecane-2-carboxylic acid ester having a structural ratio of 1.0 or more in exo-tricycloÄ5. 2. 1. 0 Üdecane-endo-2-carboxylic acid ester/endo-tricycloÄ5. 2. 1. 0 Üdecane-exo-2-carboxylic acid ester Further, the crude product of tricycloÄ5. 2. 1. 0 Üdecane-2-carboxylic acid ester thus obtained is subjected to contact treatment with specific glycol in the presence of an acid catalyst and then distilled, whereby high purity tricycloÄ5. 2. 1. 0 Üdecane-2-carboxylic acid ester which is reduced in impurity aldehyde and which is excellent in a fragrance can industrially advantageously be produced.
