BENZYL TRIMETHYL AMMONIUM CHLOIRDE FOR SYNTHESIS
Benzyltrimethylammonium Chloride or BTAC can be used as phase transfer catalyst in many biphasic organic transitions used in the agrochemicals, polymer and pharmaceutical industries. BTAC can also be used as a corrosion inhibitor in oilfield.
1. The stirrer is of the type designed by Hershberg, but it has a single paddle of 16-gauge Nichrome wire.
2. A bubble counter is employed for indicating nitrogen flow.
3. The water content of the ethanol, determined by Karl Fischer analysis, is 0.02–0.10%.
4. Benzyl chloride is redistilled before use. The fraction collected at 40–41° /6 mm. is used.
5. The flask is disconnected periodically from the gas train and stirring mechanism for weighing.
