Introduction | 4-isopropylphenol is an isopropylphenol compound. Phenylethylphenol compounds and isopropylphenol compounds are prepared by alkylation of phenol compounds and styrene compounds with Lewis acid as catalyst. As a fine chemical raw material, it has a wide range of applications and a large market demand. |
preparation | 1) under the protection of nitrogen, 188g(2mol) of phenol, 0.94g of solid acid H2SO4-SiO2 and ML of toluene were added to the reactor , heated to 85 ℃, maintained at 85 ℃, and 118g(1mol) of α-methylstyrene was added dropwise to the reactor, The dropping acceleration of α-methylstyrene was controlled so that the dropping was completed within 1 hour, and then the reaction was continued at 85 ° C. For 20 to 40 minutes to obtain a reaction solution. 2) the reaction solution is filtered to remove the solid acid H2SO4-SiO2, and 0.5% of sodium bicarbonate aqueous solution is added to the filtrate to extract , and the organic phase is taken, then extract twice with deionized water (2 × 200ml), take organic phase, spin dry toluene, add 450 ml mixture of n-hexane and toluene (1:1v/v), recrystallize, 169.6g of white crystals were precipitated, and the yield was 80%. |
