The Uses of 3,3,5-Trimethylcyclohexanol
Menthol and camphor substitute, antifoaming agent, hydraulic fluids and textile soaps, odor masking, esterification agent, pharmaceuticals,wax additive, printing inks.
Definition
ChEBI: A secondary alcohol that is cyclohexanol substituted by two methyl groups at the 3-position and one methyl group at the 5-position. It exhibits inhibitory activity against HMG-CoA reductase ( EC 1.1.1.34/EC 1.1.1.88).
Preparation
By complete hydrogenation of isophorone (Arctander, 1969).
Synthesis Reference(s)
Tetrahedron, 37, p. 1171, 1981 DOI: 10.1016/S0040-4020(01)92046-0
Hazard
Toxic by inhalation, strong irritant.
Synthesis
Trimethyl cyclohexanol is synthesized by complete hydrogenation of isoPhorone. Dehydration of the title material with Zinc chloride yields alpha-Cyclogeraniolene.
