| 以乙酸和異戊醇為原料,環(huán)己烷作帶水劑,用732陽離子交換樹脂催化合成乙酸異戊酯。探討了催化劑用量、原料配比、反應(yīng)時間、反應(yīng)溫度對合成乙酸異戊酯的影響。結(jié)果表明,合成較佳工藝條件:異戊醇11ml、乙酸10ml、環(huán)己烷6ml、催化劑0.9g,保溫回流2h,乙酸異戊酯的平均產(chǎn)率為54.6%。采用732陽離子交換樹脂作催化劑較傳統(tǒng)濃硫酸催化劑合成法具有催化效率高、酯的產(chǎn)率較高、對環(huán)境污染較小,催化劑可重復(fù)使用等優(yōu)點(diǎn)。 |

| Acetic acid and isoamylol were used as material, cyclohexane as water-carrying regent to synthesis isoamyl acetate catalyzed by 732 cation exchange resin. The amount of catalyst, proportion of material, reaction time and temperation were discussed. As a result, the better conditions of synthesis process were 11 ml of isoamylol, 10ml of acetic acid, 6ml of cyclohexane and 0.9g of catalyst with circulation reflux for 2h under constant temperature, the isoamyl acetate productive rate was 54.6% on anerage. The advantages of 732 cation exchange resin catalyst were as follows compard to traditional concentrated sulfuric acid: more efficiency, higher productive rate for ester, less environmental pollution and catalyst can be reused. |
