| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Use | for organic synthesis; Solvent. |
| production method | from the reaction of benzene and SEC-butyl chloride. The anhydrous benzene and anhydrous aluminum chloride were stirred and cooled, and SEC-Butyl Chloride was added dropwise at 0-5 ° C. After addition, the reaction was continued with stirring for 1H. Cold water was added with stirring and the reaction mixture was subjected to steam distillation. The distillate was separated into water, dried and then fractionated, and the 171-173 ° C. Fraction was collected to obtain a finished product with a yield of 77%. |
