摘要:
Deodorant of natural origin, which is useful in the fields of foodstuff, cosmetics and toiletry. This deodorant is derived from brewed wine or residual fermentation materials produced in the manufacture of brewed wine. In one aspect, this deodorant is manufactured from the brewed wine by evaporating water and alcohols from the brewed wine to obtain residual product as a deodorant. In another aspect, the residual fermentation materials are first extracted with ethanol to obtain an ethanol-extracted liquid, which is then heated to evaporate water and alcohol therefrom to obtain the product. This deodorant may further contain amino acid and/or salts of amino acid.
摘要:
A novel rhodium-phosphine complex represented by the formula (I):[Rh(BINAP).sub.2 ].sup.+ Y.sup.-wherein BINAP represents 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl, and Y represents ClO.sub.4, PF.sub.6, BF.sub.4, PCl.sub.6 or B(C.sub.6 H.sub.4) is described. This complex can be used as a catalyst for various organic syntheses and also for asymmetric syntheses such as an asymmetric isomerization reaction and an asymmetric hydrogenation reaction. Due to its high activity, the complex is very useful as a catalyst.

摘要:
Alkali metal salts of carbazole are prepared by heating carbazole and alkali metal hydroxides with stirring in an organic solvent which forms an azeotrope with water, and removing the resulting water as an azeotrope from the reaction system.The resulting alkali metal salts of carbazole are useful as a material for the preparation of vinyl carbazole for use in electrophotography. The reaction is promoted particularly by the presence of a small amount of water in the reaction system prior to heating.
摘要:
The novel compound, cyclohexadecenone-5 is prepared by reacting cyclododecanone with chlorinating agent to provide Alpha chloro-cyclododecanone-1, reacting the Alpha -chlorocyclododecanone-1 with vinyl magnesium chloride to provide 1,2divinylcyclododecanol-1, and decomposing the 1,2divinylcyclododecanol-1 with heat to cyclohexadecenone-5.
