Benzyltriethylammonium chloride (TEBA) cas:56-37-1 is a catalyst for alkylation reactions. Cationic surfactant, organic synthesis phase transfer catalyst. Synthesis of multi substituted cyclopropanes through phase transfer catalysis Michael addition reaction.
The preparation method of Benzyltriethylammonium chloride ( TEBAC ) CAS 56-37-1 is as follows: 1. Add benzyl chloride, triethylamine, and acetone to the reaction vessel and reflux at 63-64 ℃ for 8 hours. Slowly reduce to 15 ℃, filter, wash the filter cake with acetone, dry, and obtain TEBA. The yield was 68.9%. 2. Place 346.5 grams of triethylamine, 413.5 grams of chlorine and acetic acid ethyl acetate in 238.6 grams of dimethylformamide (DChemicalbookMF) and reflux for 1 hour. Add 300 grams of benzene at 80 ℃ to precipitate the ammonium salt. Filter by suction, wash with benzene, and vacuum dry to obtain 648 grams with a purity of 98.1%. 3. Alternatively, 25 grams of triethylamine and 30 grams of benzyl chloride can be refluxed in 120 grams of dichloroethane for 2 hours to obtain 52.6 grams of the product benzyl triethylammonium chloride (TEBA).
