Synthesis process of beta-damascenone

The invention belongs to the technical field of chemical synthesis of perfume essences and in particular relates to a novel synthesis process for industrial production of beta-damascenone. The synthesis process comprises the following steps: by taking 1,3-pentadiene as a starting material, performing a Diels-Alder addition reaction on the 1,3-pentadiene with 4-methyl-3-pentene-2-one under catalysis of AlCl3 firstly so as to generate 1-(2,6,6,-trimethyl cyclohexyl-3-alkenyl)-butanone; under the catalysis of a solid super strong acid catalyst, performing olefin isomerization so as to obtain 1-(2,6,6,-trimethyl cyclohexyl-1-alkenyl)-butanone; and finally, performing a hydroxyaldehyde condensation reaction with acetaldehyde, so as to generate a target product, namely beta-damascenone. The synthesis process provided by the invention has the main advantages that the raw material cost is low, the energy consumption is low, a gas-phase reaction catalyzed by the solid super strong acid catalystis implemented in an olefin isomerization production process, the product purity is high, no reaction solvent is needed, a very small amount of wastewater or waste gas is generated, and in addition,the catalyst is good in reuse performance.

PROCESS FOR CONDUCTING AN ORGANIC REACTION IN IONIC LIQUIDS

The present disclosure describes processes for producing cyclohexenes using Lewis acidic ionic liquids comprising the steps of providing to a reactor an α,β-unsaturated carbonyl dienophile, providing to the reactor a 1,3-diene, providing a Lewis acidic ionic liquid to the reactor; and reacting the α,β-unsaturated carbonyl dienophile with 1,3-diene to form a substituted cyclohexene product. The α,β-unsaturated carbonyl dienophile can be mesityl oxide, the 1,3-diene can be piperylene; and the Lewis acidic ionic liquid can be AlCl3:[C2mim]Cl; AlCl3:[C8mim]Cl; or mixtures thereof.

Production process of cyclohexenyl ketones

An economical process for producing (2- and/or 1-)cyclohexenyl methyl ketones which are intermediates for the synthesis of α- or β-damascone. In the presence of a catalyst, a 3-cyclohexenyl methyl ketone represented by the following formula (1a): wherein, R1, R2 and R3 each independently represents a hydrogen atom or a methyl group and at least two of R1, R2 and R3 are methyl groups, is isomerized.
