用水杨酸和间甲酚为原料,在三氯氧磷和氯化锌的作用下合成了(4-羟基-2-甲基苯基)(2-羟基苯基)甲酮(C14H12O3),通过IR、NMR、元素分析、X射线单晶衍射等手段对化合物进行了结构表征.该晶体属于单斜晶系,空间群为P2(1)/n,晶胞参数为:a=1.095 34(10),b=0.846 16(6),c=1.304 58(19)nm,α=γ=90°,β=109.584(2)°,V=1.139 2(2)nm3,Z=4,Mr=228.24,Dc=1.331 g/cm3,μ=0.093 mm-1,F(000)=480,羟基和羰基中的氧原子所形成的分子间氢键把分子连接成一维链.该化合物在240~360 nm之间有强烈的紫外吸收.
(4-hydroxy-2-methylphenyl) (2-hydroxyphenyl) methanone (C14H12O3) was synthesized by salicylic acid and m-cresol under the action of phosphorus oxychloride and zinc chloride. The crystal belongs to the monoclinic system with space group P2 (1) / n. The unit cell parameters are: a = 1.095 34 (10) , b = 0.846 16 (6), c = 1.304 58 (19) nm, α = γ = 90 °, β = 109.584 (2) °, V = 1.139 2 (2) nm3, Z = 4, Mr = 228.24 , D = 1.331 g / cm3, μ = 0.093 mm-1, and F (000) = 480. The intermolecular hydrogen bonds formed by the oxygen atoms in the hydroxyl group and the carbonyl group link the molecules into one- There is a strong UV absorption.
