YieldReaction ConditionsOperation in experiment
98.3%
Stage #1: With pyridine In methanol; toluene at 5 - 40℃;
Stage #2: With phosphorus trichloride In methanol; toluene at 95℃; for 0.5 h;
(1)First, 11.0 g of 2,4-di-tert-butylphenol was added to a three-necked flask.a diatomaceous earth-supported pyridine catalyst of 22 mg and a mixed solution of methanol and toluene in 400 mL, and then added to the rotor, and a reflux condenser,The thermometer and the dropping funnel were fixed on a three-necked flask;(2)The three-necked flask containing the reactant in the step (1) was heated under an oil bath condition at a rate of 5 degrees Celsius per ten minutes.Raise the temperature to 40 ° C,Reacting solution;(3)To the reaction liquid of the step (2), 5.57 g of phosphorus trichloride dissolved in 30 mL of toluene was added dropwise to control the dropping rate.After 15 minutes of dropwise addition, continue to heat up to 95 ° C,The reaction was kept for 30 minutes, and the solvent was distilled off under reduced pressure.Recrystallization from n-hexane,That is, the product is obtained.The yield of the final product was 98.3percent.The purity was 98.9percent.
