Appearance: Colorless or pale yellow liquid ; Assay：99%min by GC ; IR Identity: conform to standard ; HNMR： conform to standard ; carbon spectrum: conform to standard ; Water by K. F.:0.5% max or as per the customer’s request ; Loss on drying:0.5% max. or as per the customer’s request ; Melting point: 31–33 °C; boiling point: 213.3 °C（760 mmHg）; ============================================================================= synthetic route The standard industrial synthesis pathway for this compound is the Grignard reaction method, with the following specific steps: Preparation of Grignard reagent: Bromobenzene (C ₆ H ₅ CH ₂ CH ₂ Br) reacts with magnesium metal in anhydrous ether or tetrahydrofuran (THF) to produce phenethyl magnesium bromide (C ₆ H ₅ CH ₂ CH ₂ MgBr). Nucleophilic addition reaction: Phenylethyl magnesium bromide reacts with acetone (CH3 COCH3) at low temperatures (0-5 ° C) to undergo nucleophilic addition, resulting in the formation of a tertiary magnesium alkoxide intermediate. Acidic hydrolysis: The reaction mixture is hydrolyzed with dilute acid (such as dilute hydrochloric acid or ammonium chloride solution) to obtain the target product 2-methyl-4-phenyl-2-butanol. Reaction characteristics: Mild reaction conditions and high yield (literature reports>70%) No need for transition metal catalysts, suitable for industrial production Product purification can be achieved through vacuum distillation or silica gel column chromatography Uses : as an intermediate in organic synthesis Synonyms : Benzenepropanol, alpha,alpha-dimethyl-;1,1-Dimethyl-3-phenyl-1-propanol;1,1-Dimethyl-3-phenylpropanol;1,1-Dimethyl-3-phenylpropyl alcohol;2-(2-Phenylethyl)-2-propanol;2-Butanol, 2-methyl-4-phenyl-;2-Phenethyl-2-propanol;4-06-00-03380 (Beilstein Handbook Reference);AI3-24192;BRN 2076770;Benzyl-t-butanol;Benzyl-tert-butanol;Dimethyl phenylethyl carbinol;Dimethylphenethylcarbinol;Dimethylphenylethyl carbinol;Dimethylphenylethylcarbinol;FEMA No. 3629;NSC 62145;Phenethyl dimethyl carbinol;Phenylethyl dimethyl carbinol;alpha,alpha-Dimethyl-gamma-phenylpropyl alcohol;alpha,alpha-Dimethylbenzenepropanol;1-Propanol, 1,1-dimethyl-3-phenyl- (8CI);2-Methyl-4-phenylbutan-2-ol;4-phenylpentan-2-ol; Molecular Structure :
