摘要： Provided is a process in which a cyclobutanediol compound having a high cis:trans ratio can be stably obtained. The cyclobutanediol compound having a cis:trans ratio of 1.5:1 to 5000:1 is produced by using at least one compound selected from a group consisting of a cyclobutanedione compound, a cyclobutanketol compound, and a cyclobutanediol compound as a raw material, and performing a catalytic hydrogenation reaction and an isomerization reaction in the cyclobutanediol compound in a solid phase state in the presence of a metal catalyst without adding a solvent.

摘要： A chemical reaction is catalyzed in an organic solvent using a water soluble N-heterocyclic carbene homogeneous catalyst to form a reaction mixture. An aqueous phase in the reaction mixture. A solvent in which the catalyst is insoluble is added to the reaction mixture, causing the catalyst to migrate to the aqueous phase to form a catalyst-laden aqueous phase. The catalyst is extracted from the catalyst-laden aqueous phase.

摘要： The invention makes public a preparing method for xanthophyll crystals with higher content of zeaxanthin from plant oleoresin. The current methods generally are to get quite pure crystal forms of xanthophyll or zeaxanthin, and they refer to several separation steps. The invention mixes the xanthophyll diester-containing plant oleoresins and food grade alcohol solvents to form even solution, and then soap-dissolve the solution under an alkaline environment; then replenish organic solvents and emulsifiers into the reaction solution and drop some alkali solution into the solution to make partial xanthophyll crystals be transformed to be zeaxanthin through epimerization reaction; after the reaction is finished, add the mixed solvents of alcohol solvent and water to separate out the crystals; use the method of centrifugation or filtration to get the crystals; wash the crystals several times with the mixed solution of deionized water and alcohols to remove the impurities among the crystals; recrystallize the gained crystals with absolute ethyl alcohol, and then dry the crystals to get the products. The invention can gain mixture crystals that contain xanthophyll and zeaxanthin at one time in quite high collection rate, and it is convenient for the followed product application.

摘要： The current invention provides novel bifunctional catalysts. The bifunctional catalysts are prepared from phosphine ligands and a cyclopentadienyl metal complex and are useful for forming isomers of hydrocarbon species. The hydrocarbon can be an alkenol having the alkene and alcohol groups far apart and the catalyst will move the double bond across numerous carbon atoms. The hydrocarbon can also be an achiral alkenol and the catalyst will form a chiral alcohol therefrom. Moreover, deuterated water may be added to the isomerization reaction mixture for forming deuterated hydrocarbon species.
