The invention provides: an isopropyl alcohol-producing bacterium which has an acetoacetate decarboxylase activity, an isopropyl alcohol dehydrogenase activity, a CoA transferase activity and a thiolase activity having been imparted thereto and is capable of producing isopropyl alcohol from a plant-derived material; a method of producing isopropyl alcohol whereby isopropyl alcohol is produced from a plant-derived material by using this isopropyl alcohol-producing bacterium; and an apparatus therefor.

Isopropyl alcohol-producing bacterium and method of producing isopropyl alcohol using the same

A novel olefin production process of the invention can be established as an industrial and practical process of producing an olefin with high selectivity by directly reacting a ketone and hydrogen in a single reaction step. In particular, a novel olefin production process is provided in which propylene is obtained with high selectivity by directly reacting acetone and hydrogen. An olefin production process of the invention includes reacting a ketone and hydrogen at a reaction temperature in the range of 50 to 300° C. in the presence of a Cu-containing hydrogenation catalyst and a solid acid substance.

Olefin production process

The invention has objects of providing an olefin production method which can produce an olefin with high efficiency by the dehydration reaction of an alcohol even in the presence of a ketone without the occurrence of side reactions such as the Aldol condensation of the ketone, as well as providing an olefin production method which can produce an olefin with high activity and high selectivity in a single reaction step by directly reacting a corresponding ketone and hydrogen The former olefin production method of the invention produces an olefin from an alcohol using a silica gel (A) as a dehydration catalyst which is obtained by bringing a silica gel (X) prepared from an alkyl orthosilicate into contact with a water-soluble aluminum compound and calcining the contact product or is obtained from a wet-process silica gel (Y) prepared from an alkali silicate and which contains an aluminum compound at 10 to 1000 ppm in terms of aluminum element as well as an alkali metal and an alkaline earth metal at a total of 0 to 350 ppm The latter olefin production method produces an olefin from a ketone and hydrogen in a single reaction step in the presence of the silica gel (A) and a silver-containing inorganic substance (B)

PROBLEM TO BE SOLVED: To contribute to the issues of environments and energy resources by replacing the petrolic materials used for printing on shrink labels as much as possible with the materials obtained from recyclable biologic resources. SOLUTION: This is a printed shrink label obtained by using the ink composition satisfying the following condition 1. Condition 1: a cellulose series resin is used for the main components of the binder; an alcohol system solvent and/or a fatty acid ester system solvent manufactured from recyclable biologic resources is used for the main components of the solvent, and further, the total amount of the materials manufactured from recyclable biologic resources is more than 50 mass% of the total ink compositions.

FIELD: chemistry.SUBSTANCE: subject of present invention is a novel method of producing olefins which is characterised as a cheap industrial process of producing olefins by direct reaction of a ketone and hydrogen in a single step. In particular, described is a novel method of producing olefins, wherein propylene is obtained with high selectivity by direct reaction of acetone with hydrogen. The method of producing olefins provided by the present invention involves reaction of a ketone and hydrogen in the presence of at least one dehydration catalyst and a silver-containing catalyst. The dehydration catalyst is selected from metal oxide catalysts which contain at least one group 6 (VIB) element, zeolites, aluminium oxides and salts of heteropoly acids wherein some or all protons in the heteropoly acids are replaced with metal cations.EFFECT: providing a method of producing olefins.9 cl, 3 tbl, 9 ex

Method of producing olefins

PURPOSE: To produce isopropyl alcohol in high efficiency by fermentation process, by culturing a specific microbial strain in a medium, and separating isopropyl alcohol from the culture liquid. CONSTITUTION: Clostridium sp. 172CY-02 or Clostridium sp. 64CY-05 is cultured in a medium, and isopropyl alcohol is separated from the culture liquid. The 172CY-02 strain and the 64CY-05 strain have been deposited in the Fermentation Research Institute as FERM-P No.7738 and FERM-P No.7823, respectively. The culture medium contains corn, glucose, galactose, molasses, etc. as carbon source, an inorganic or organic nitrogen compound as nitrogen source, and other nutrient source containing inorganic salts and vitamins.
