| | 3,7-DIMETHYL-1-OCTANOL Usage And Synthesis |
| Chemical Properties | Tetrahydrogeraniol has been identified
in citrus oils and is a colorless liquid with a waxy, rose-petal-like odor. It is
prepared by hydrogenation of geraniol or citronellol in the presence of a nickel
catalyst and is a by-product in the synthesis of citronellol from geraniol or nerol.
Because of its stability, it is often used to perfume household products. | | Chemical Properties | 3,7-Dimethyl-1-octanol has a sweet, rosy odor and bitter tas | | Chemical Properties | Clear colorless liquid | | Uses | 3,7-Dimethyl-1-octanol was employed as medium supplement in the anaerobic enrichment cultures of Pseudomonas citronellolis.2 | | Preparation | Usually prepared by hydrogenation of geraniol, citronellol or citronellal. | | Production Methods | 3,7-Dimethyl-1-octanol is commercially produced by the
reduction of geraniol or by the reduction of citronellol,
citronellal, or citral. It is used in fragrances and in
foods. | | Aroma threshold values | Aroma characteristics at 1%: fresh fatty, waxy, soapy, aldehydic citrus with lemon, lime and orange
nuances. It has rosy and green woody notes | | Taste threshold values | Taste characteristics at 1 to 10 ppm: fatty, waxy, soapy with floral rosy and fresh citrus-woody nuances.
Natural occurrence: Reported found in lemon, lemon peel oil and thyme; corresponds to the dl-form of dihydro-citronellol. | | General Description | 3,7-Dimethyl-1-octanol is an fragrance ingredient and its toxicologic and dermatologic review as a fragrance ingredient was reported. | | Flammability and Explosibility | Nonflammable | | Safety Profile | Moderately toxic by
skin contact. A skin irritant. When heated to
decomposition it emits acrid smoke and
irritating fumes. |
