Storage method

This product should be kept sealed and dry.

Synthesis method

1. Add benzyl chloride, triethylamine, and acetone to the reaction pot and reflux at 63-64°C for 8 hours. Slowly lower to 15°C, filter, wash the filter cake with acetone, and dry to obtain TEBA. The yield is 68.9%. The reaction formula is as follows:

2.Place 346.5 grams of triethylamine, 413.5 grams of chlorine and ethyl acetate in 238.6 grams of dimethylformamide (DMF) and reflux for 1 hour, add 300 Gram benzene,precipitates ammonium salt. Suction filter, wash with benzene, and vacuum dry to obtain 648 grams, purity 98.1%
You can also place 25 grams of triethylamine and 30 grams of benzyl chloride in 120 grams of dichloroethane and reflux for 2 hours to obtain 52.6 grams Products
