Selective hydration of dihydromyrcene in ionic liquids

Acid catalysed direct hydration of dihydromyrcene to dihydromyrcenol proceeds selectively in ionic liquid media. By making use of the tuneable physicochemical properties of ionic liquids, and depending upon the process requirement, either biphasic or triphasic systems can be developed. The selectivity to dihydromyrcenol remains extremely high over a wide range of reaction conditions.

PRO-FRAGRANCE COMPOUNDS

A compound of Formula (I) wherein R1 represents a C3 to C20 hydrocarbon group derived from a fragrant alcohol of formula R1OH or from a fragrant aryl aldehyde or ketone of Formula (II), wherein: R2 is, independently, hydrogen atom, hydroxyl group, acetoxy group, -O(C=O)CH(CH3), optionally substituted C1-C6 alkyl group or C1-C6 alkoxy group, wherein any two of R2 may form an optionally substituted 5 or 6 membered ring, and R1 represents a radical derived from a fragrant alcohol of formula R1OH or from a fragrant aldehyde or from a fragrant aryl aldehyde or ketone of formula (II). The compounds are useful for example as a precursor for the prolonged delivery or release of fragrant compounds such as fragrant alcohols or aldehydes.

METHOD FOR SELECTIVE HYDRATION OF AROMA OLEFINS TO ALCOHOLS IN CONTINUOUS SOLID CATALYST COLUMN REACTOR

Present invention is related to method for selective hydration of aroma olefins to alcohols in continuous solid catalyst column reactor. The invention discloses the continuous production of unsaturated aroma alcohol and/or ester comprising of C10-12 carbon chain by selective solid acid catalyzed hydration reaction. According to the process of the invention production of Octa-1-ene-7- ol, 3,7-dimethyl- (Dihydromyrcenol) and/or dihydromyrcenyl acetate can be carried out by passing 1,6-Octadiene, 3,7-dimethyl- (dihydromyrcene) and water continuously through a packed bed column reactor wherein the residence time of column is not more than 90 minutes and reaction temperature not substantially above 100 degree C. The present disclosure solves the problem of effluent treatment and increases the yield of the process due to selectivity in reaction.

CATALYTIC REACTION-RECTIFICATION INTEGRATED PROCESS AND SPECIALIZED DEVICE THEREOF

A catalytic reaction-rectification integrated process and a catalytic reaction-rectification integrated column (T-01), the specialized device of such process. The process comprises that the reactants are preheated and mixed with catalysts, and then fed into a jet agitation reaction section (6) located in the middle of the catalytic reaction-rectification integrated column (T-01) from a feeding inlet. The jet agitation reaction section (6) is a kettle-like reactor located in the middle of the catalytic reaction-rectification integrated column (T-01). After pressurized by a centrifugal pump (21), the reactant materials are admitted into a subsonic or transonic agitator (33) located within the reaction section (6). The reactant materials are ejected into the jet agitation reaction section (6) at high speed, to efficiently mix the solid and liquid phases in the reaction section (6) and to reinforce heat and mass transfer efficiency during the reaction. The liquid reaction mixture is separated and purified directly in the catalytic reaction-rectification integrated column (T-01). This process may be used for esterification, the production of alcohols from olefins and water, and the production of ethers from olefins and alcohols.

Compounds having protected hydroxy groups

The present invention relates to compounds with protected hydroxy groups of formula (I) These compounds are precursors for organoleptic agents, such as fragrances, and masking agents and for antimicrobial agents. When activated, the compounds of formula (I) are cleaved and form one or more organoleptic and/or antimicrobial compounds.

PERFUME COMPOSITION

A perfume composition contains specified ketones, salicylates and alcohols/acetates/propionates. Use of such a perfume composition inhibits development of human body malodour. The combination of specified materials makes it possible to avoid inclusion of individual components with powerful, unacceptable odours. The perfume composition may be used in various products notably in a fabric conditioning product used during the rinsing or tumble drying of fabrics after washing to soften the fabrics.

Cyclic trimers of aldehydes, organoletpic uses thereof and process for preparing same

Described are novel aldehyde cyclic trimers which are useful for controllably releasing fragrance composition components into the environment surrounding the location of said trimers. The trimers are particularly useful in effecting malodor elimination from solid or semisolid surfaces, e.g., the human epidermis (skin) and surfaces that have a displeasing tobacco aroma.

Amounts of material within each category fall within specified ranges of percentage of the whole composition. Two categories, ethers and salicylates, must be present. At least two of the remaining three categories, which are alcohols, acetate/propionate esters and methyl aryl ketones, must also be present. The compositions enable good levels of deodorant activity to be achieved along with consumer-acceptable fragrance.

Preparation of dihydromyrcenol

Dihydromyrcenol (3,7-dimethylocta-1-en-7-ol) and carboxylic acid esters thereof are prepared from dimethylcyclooctene reactant mixtures comprising 1,5-dimethylcyclooctene in admixture with 1,6-dimethylcyclooctene and/or 1,4-dimethylcyclooctene by (a) thermally isomerizing the dimethylcyclooctene reactant mixture to afford a mixed octadiene product comprising 2,6-dimethylocta-1,7-diene in admixture with 2,7-and/or 2,5-dimethylocta-1,7-diene, (b) reacting the mixed octadiene product with a carboxylic acid to selectively form the ester of 3,7-dimethyl-octa-1-en-7-ol and (c) optionally hydrolyzing the ester of 3,7-dimethyl-octa-1-en-7-ol under basic conditions to yield dihydromyrcenol.
