羧酸和乙醇在氧化石墨烯(50%wt)催化下,100℃反应24 h,发生酯化反应得到相应的羧酸乙酯类化合物,芳香羧酸25例收率50%~98%,脂肪羧酸4例收率85%~93%。芳香羧酸在1,2-二氯乙烷中与其他醇(3倍摩尔量)在同样条件下反应生成酯,23例收率51%~97%,芳环上连有吸电子基团或给电子基团均可得到较高收率。 Carboxylic acid and ethanol were reacted at 100 ℃ for 24 h under the catalysis of graphene oxide (50% wt) to obtain the corresponding carboxylic acid ethyl ester compounds. The yield of aromatic carboxylic acids was 50% ~ 98% 4 cases of carboxylic acid yield of 85% to 93%. Aromatic carboxylic acids reacted with other alcohols (3-fold molar amount) in 1,2-dichloroethane under the same conditions to yield esters in 23% yield of 51% -97%. The aromatic rings were linked with electron-withdrawing groups or Give electron groups can get higher yield.
