摘要
在磷酸二氢钠催化下,由冰乙酸和正丁醇合成乙酸丁酯.结果表明:当冰乙酸∶正丁醇∶NaH2PO4.2H2O=1∶1.5∶0.09(摩尔比)时,2 h内酯收率可达94%,磷酸二氢钠重复使用多次,催化活性没有降低.
n-Butyl acetate was synthesized from acetic acid and 1-butanol in the presence of sodium dihydrogen phosphate catalyst. The yield of the ester could be 94% under the ratio of acetic acid, 1-butanol and sodium dihydrogen phosphate was 1 ： 1.5：0.09（mole ratio） in the period of 2 hours. The phosphate could be used for times without reduce of catalytic activity.
