| | 2-METHYL-4-PHENYL-2-BUTANOL Usage And Synthesis |
| Description | 2-Methyl-4-phenyl-2-butanol has a floral green, fruity, linalool
character with a mildly herbaceous odor. May be prepared by
reaction of phenylethyl magnesium chloride with acetone. | | Chemical Properties | 2-Methyl-4-phenyl-2-butanol has a floral, green, fruity, linalool character and mildly herbaceous odor. | | Chemical Properties | Colorless or light yellow liquid | | Chemical Properties | 2-METHYL-4-PHENYL-2-BUTANOL is a colorless
liquid with a dry, floral, lily-like odor. It has been identified in cocoa aroma
and is prepared by a Grignard reaction of benzylacetone and methyl magnesium
chloride. It is used in blossom compositions. | | Occurrence | Has apparently not been reported to occur in nature. | | Uses | 2-Phenethyl-2-propanol is a useful reagent in preparation of phenyldimethylsilyl group as a masked hydroxy group. | | Preparation | By reaction of phenylethyl magnesium chloride with acetone | | Aroma threshold values | Aroma characteristics at 1.0%: clean, fresh, floral reminiscent of rose and violet | | Taste threshold values | Taste characteristics at 10–40 ppm: floral, rosy, oily with a slight fruity nuance | | Synthesis Reference(s) | The Journal of Organic Chemistry, 60, p. 4922, 1995 DOI: 10.1021/jo00120a042 | | Safety Profile | Moderately toxic by ingestion andskin contact. When heated to decomposition it emits acridsmoke and irritating fumes. |
