Usage

General Description

Tetrahydroionol is a fragrance ingredient used in the production of perfumes and cosmetics. It is a clear, almost colorless liquid with a pleasant floral and herbal odor. This chemical is commonly used as a fragrance in personal care products and has a sweet, woody, and floral scent. Tetrahydroionol is also known for its fixative properties, which help to prolong the aroma of other fragrances in a product. It is considered safe for use in cosmetics and personal care products and is often used to add depth and complexity to fragrance formulations.

Liquid-phase Hydrogenation of β-Ionone on a Stationary Ni-Cr2O3 Catalyst in a Flow Apparatus under Hydrogen Pressure

We have studied the effect of various parameters (pH2, T deg C, H2 flow rate, etc.) on the kinetics and the selectivity of the hydrogenation of β-ionone on an industrial Ni-Cr2O3 catalyst in a flow apparatus by the "counter-current" and the "jet" method.Under comparable conditions the counter-current method offers an output approximately double that of the jet method, with a yield of dihydro-β-ionone approximately 6-8percent lower.

Active Metals from Potassium-Graphite. Air-Oxidized Nickel-Graphite as a New Selective Hydrogenation Catalyst

Air exposure of Ni-Gr1 affords a modified, less active hydrogenation catalyst (air-oxidized nickel-graphite, Ni-Gr2), owing to a partial oxidation of the metal, which is able to reduce carbon-carbon, carbon-oxygen, and carbon-nitrogen multiple bonds under 30 atm of hydrogen in the temperature range 30-130 deg C.A remarkable bond selectivity in the hydrogenation of polyfunctional molecules such as unsaturated carbonyl compounds and β-diketones is observed.
