摘要
将倍酸和焦倍酸两个多羟基化合物与Fe(Ⅱ )组成的催化体系 ,用于苯的过氧化氢直接羟化反应 ,获得良好的苯的转化率和对苯酚的选择性。反应体系中未引入有害物质。重点考察了Fe(Ⅱ ) /酸配体物质的量比、催化剂用量、反应温度和时间对苯羟化反应的影响。
Direct Oxidation of benzene to phenol with hydrogen peroxide over Fe(Ⅱ)-gallic acid (3,4,5-trihydroxybenzoic acid)and Fe(Ⅱ)-pyrogallic acid (1,2,3-trihydroxybenzene) complex catalysts was investigated.High selectivity and yields for phenol were obtained.The influence of Fe(Ⅱ)/acid molar ratios,the amount of catalyst,reaction time and temperature was studied.
