摘要
2-叔戊基蒽醌可作为双氧水生产过程中的工作载体,具有广阔的应用前景。
本文主要对2-叔戊基蒽醌的合成方法进行了研究,建立了一条新的合成工艺路线,得到了目标产物2-叔戊基蒽醌。研究工作主要包括以下三个方面:
叔戊基苯的合成:将叔戊醇与苯按1:9的摩尔比加入反应体系,然后在三氯化铝的催化作用下发生Friedel-Crafts烷基化反应,待反应结束后用苯萃取,经减压蒸馏后得到叔戊基苯。实验结果表明:在n(

n(叔戊醇)=1:0.8的条件下,叔戊基苯的收率平均可达79.61%(以叔戊醇计)。
2-(4'-叔戊基苯甲酰)苯甲酸的合成:依次将邻苯二甲酸酐、三氯化铝、三乙胺、氯苯加入反应体系并混合均匀,然后向体系中滴加叔戊基苯,控制温度15℃
下反应5h得到产物2-(4'-叔戊基苯甲酰)苯甲酸。实验结果表明:在n(
三氯化铝)
:n(叔戊醇)
= 1:0.9、n(苯酐):n(氯苯)= 1:13、反应温度15℃、反应时间5h的条件下,2-(4'-叔戊基苯甲酰)苯甲酸的收率平均可达80.36%(以叔戊基苯计)。
2-叔戊基蒽醌合成:先将2-(4'-叔戊基苯甲酰)苯甲酸溶解在氯仿中加入到反应体系,然后恒温下将浓硫酸滴加到反应体系中,之后蒸出氯仿;接着升温到110℃反应2h后停止反应得到产物2-叔戊基蒽醌。实验结果表明:在n(浓硫酸):n(ABB 酸)美丽的回忆
pboc=50:1、反应温度110℃、反应时间2h条件下,2-叔戊基蒽醌的收率平均可达82.5%(以2-(4'-叔戊基苯甲酰)苯甲酸计)。

Abstract
2–tert-amylanthraquinone as a carrier in the process of hydrogen peroxide production plays an important role and broad application prospects.This article is mainly for synthesis of 2–tert-amylanthraquinone,and create a new synthetic route. Rearch work is mainly around the following three aspects:
The synthesis of tert-amyl benzene: tert-amyl alcohol and benzene by the molar ratio of 1:9 join reaction system, and then under the catalysis of aluminium trichloride proceed Friedel - Crafts alkylation reaction, after the reaction finished, extract with benzene, after vacuum distillation get tertiary amyl benzene.The experimental results show that: when n (AlCl3) : n (C6H6) = 1:9, reaction temperature 6-8℃, reaction time is 4 to 5 h, n (AlCl3): n (tert-amyl alcohol) = 1:0. 8, the average yield of tert-amyl benzene can reach 79.61% (with benzene).
The synthesis of 2- (4'-tert-amyl benzoyl) benzoic acid: phthalic anhydride, aluminium chloride, triethylamine and chlorobenzene was added in the reaction system in turn, and mixed evenly, then add to the system of tertiary amyl benzene, control temperature 15 ℃,under 5 h reaction product 2-(4'–tert-amyl benzoyl) benzoic acid.The experimental results show that: when n (AlCl3) : n (tert-amyl alcohol) = 1:0. 9, n (phthalic anhydride) : n (C6H5Cl) =1:13,T= 15℃, reaction time was 5 h, the yield of 2-(4'-tert amyl benzoyl) benzoic acid can reach 80.36% (with tert-amyl benzene).
The synthesis of 2-tert-amylanthraquinone: First, 2-(4'-tert-amyl benzene formyl) benzoic acid dissolved in chloroform was added to the reaction system, and then at a constant temperature ,concentrated sulfuric acid was added dropwi to the reaction system, then the reaction temperature was raid to 110°C.After 2h stopped the reaction and got 2-tert-amylanthraxquinone. The results show that: when n (H2SO4): n (ABB acid)=50:1,reaction temperature 110℃,reaction time 2h, 2-tert-amylanthraqui- none yield up to 82.5% on average.
Qualitative and Quantitative analysis of 2-tert-amylanthraquinone and tert-amyl benzene: 2-tert-amylanthraquinone has strong UV absorption, and therefore high performance liquid chromatography was ud to the qualitative and quantitative analysis of 2-tert-amylanthraquinone . Experiment to determine the chromatographic conditions: Agilent1200 high performance liquid chromatography, HC-C18 column (250nm × 4.6mm, 5μm), UV detector (255nm), the mobile pha (V (CH3OH): V (H2O)
