以Fe(NO3)3.9H2O和氨含量为28%的氨水为原料,制备了Fe2O3.SO24-固体超强酸催化剂,在该固体超强酸的催化作用下,由长链醇和苯酚合成了系列长链烷基酚。通过分析比较在不同条件下反应产物产率的变化,考察了催化剂焙烧温度、催化剂用量、反应时间、反应温度和醇/酚摩尔比对烷基化反应的影响。结果表明,Fe2O3.SO24-固体超强酸对长链醇与苯酚的烷基化反应有良好的催化效果,焙烧温度为550℃时催化剂的催化活性最佳;醇/酚摩尔比、反应温度、反应时间和催化剂用量的最佳值均随烷基链的增长略有增加。 A series of long chain alkanes (Fe3O4) were synthesized from long-chain alcohols and phenol catalyzed by Fe (superscript 3+) 3 SO4-solid superacid with Fe (NO3) 3.9H2O and ammonia solution of 28% Phenol. The effects of calcination temperature, amount of catalyst, reaction time, reaction temperature and alcohol / phenol molar ratio on the alkylation reaction were investigated by analyzing the changes of the yield of the reaction products under different conditions. The results showed that Fe2O3.SO24-solid superacid had a good catalytic effect on the alkylation of long-chain alcohols with phenol. The best catalytic activity was obtained when the calcination temperature was 550 ℃. The molar ratio of alcohol to phenol, reaction temperature, reaction time The optimum values ​​of time and amount of catalyst both increased slightly with the increase of alkyl chains.
