Title: Synthesis of 4-(1-phenylethyl)-1,3-resorcinol catalyzed by ionic liquids
Abstract: 4-(1-Phenylethyl)-1,3-resorcinol was synthesized by the Friedel-Crafts reaction using resorcinol and styrene as raw materials and ionic liquid N-methyl pyrolidone bisulfate salt([Hnmp]HSO4)as the catalyst,.The optimum reaction conditions were obtained by orthogonal experiment program as follows:the molar ratio of n(resorcinol)∶n(styrene)was 1.5∶1.0,the dosage of catalyst [Hnmp]HSO4 was 2.5%,the reaction temperature was 105 ℃,and the reaction time was 6 h,with toluene being used as the solvent.The overall product yield was 85.7%.The structure of product was determined by melting point measurements,IR spectrometry,ESI-MS spectrometry and 1HNMR spectrometry that were applied to verify the target product.
