摘 要:以大孔強酸性陽(yáng)離子交換樹(shù)脂作催化劑,在不同條件下催化合成乳酸甲酯。實(shí)驗結果表明:在催化劑作用下,反應溫度60℃,流速180 g/h,物料比n(甲醇) ∶ n(乳酸)=2 ∶ 1,酯化收率達85.36﹪。 |
關(guān)鍵詞:乳酸甲酯;交換樹(shù)脂;催化;酯化 |

Abstract:Synthesis of methyl lactate on the cation exchange resin was studied under the diffrent conditions. The optimal conditions of esterification from a sevies experiments were achieved as follow∶ molar ratio of methanol to lactic acid was 2 ∶ 1,reaction temperature 80℃,velocity of flow 180 g/h and the yield of esterification could reach 85.36% under the catalyst. |
Key words:methyl lactate;ion exchange resin;catalysis;esterification |
