Yield:-
Reaction Conditions:
with sodium hydroxide in toluene at 140 - 150; under 4500.45 - 6000.6 Torr; for 1 h;
Steps:
1-3
The vaporized carbon dioxide gas is continuously introduced into the toluene suspension of sodium phenate to carry out the carboxylation reaction. During the reaction, the temperature of the kettle is controlled to be 140150, and the pressure is 0.6Mpa0.8Mpa. When the pressure of the kettle no longer drops, stop Carbon dioxide was passed through, the pressure was maintained for 1 hour, the reaction was terminated, the temperature was lowered, and nitrogen was replaced to obtain a toluene suspension of sodium salicylate.
