The present disclosure describes processes for the epimerization of a cyclohexene comprising the steps of providing to a reactor a first isomer of a 1-(2-alkyl-3-cyclohexen-1-yl)-alkanone compound according to Formula I wherein Rad Rare each independently C-Calkyl, and R, R, R, R, R, and Rare each independently selected from the group consisting of H and C-Calkyl; and epimerizing the first isomer of the 1-(2-alkyl-3-cyclohexen-1-yl)-alkanone with a metal alkoxide base to form a second isomer of the 1-(2-alkyl-3-cyclohexen-1-yl)-alkanone.

Processes for epimerizing cyclohexenyl ketones with subsequent aldol condensation to produce fragrance compounds

The present disclosure describes processes for producing cyclohexenes using Lewis acidic ionic liquids comprising the steps of providing to a reactor an &#x3b1;,&#x3b2;-unsaturated carbonyl dienophile, providing to the reactor a 1,3-diene, providing a Lewis acidic ionic liquid to the reactor; and reacting the &#x3b1;,&#x3b2;-unsaturated carbonyl dienophile with 1,3-diene to form a substituted cyclohexene product. The &#x3b1;,&#x3b2;-unsaturated carbonyl dienophile can be mesityl oxide, the 1,3-diene can be piperylene; and the Lewis acidic ionic liquid can be AlCl:[Cmim]Cl; AlCl:[Cmim]Cl; or mixtures thereof.

Process for conducting an organic reaction in ionic liquids

Processes for producing intermediate materials used for perfumery, specifically, epimerized cyclohexenyl ketones, are disclosed. Processes for employing the epimerising reaction in an Aldol condensation reaction are also disclosed.

Process for epimerising cyclohexenyl ketones and its application in Aldol condensation process

Process for the conversion of sodium bromide to anhydrous hydrobromic acid and sodium bisulfate, said process with the following sequential steps: reaction of sodium bromide and sulfuric acid in a solution of water to produce hydrobromic acid and sodium bisulfate wherein the conversion of sodium bromide is greater than about 99%; adsorption of iron bromide onto a solid adsorbent; separation of hydrobromic acid and water from the sodium bisulfate; separation and drying of hydrobromic acid; and solidification of the sodium bisulfate into a flaked or granular form.

Conversion of sodium bromide to anhydrous hydrobromic acid and sodium bisulfate

Process for the conversion of sodium bromide to anhydrous hydrobromic acid and sodium bisulfate, said process with the following sequential steps: reaction of sodium bromide and sulfuric acid in a solution of water to produce hydrobromic acid and sodium bisulfate wherein the conversion rate is greater than about 95%; separation of hydrobromic acid and water from the sodium bisulfate; separation of hydrobromic acid from water; and drying of hydrobromic acid.
