甲酸甲酯合成路线

甲酸甲酯上下游产品

甲酸甲酯上游产品

甲酸甲酯下游产品

甲酸甲酯制备

1.直接酯化法　由甲酸与甲醇进行酯化而得。将无水氯化钙和甲酸混合，搅拌冷却。慢慢加入甲醇。回流2.5h，蒸馏即得成品。反应时也可以不加氯化钙将甲酸与甲醇加热回流，蒸馏收集相对密为0.947的馏出液，得甲酸甲酯，收率为90%。原料消耗定额：甲酸845kg/t、甲醇600kg/t。

2.二氧化碳法在三氟化硼的甲醇溶液中，以铱络合物作催化剂，通入二氧化碳和氢气，在100℃，5.88MPa下反应生成甲酸甲酯。

3.甲醇羰基化法。

4.甲醇脱氢法。

5.甲醇氧化脱氢法。

6.合成气一步合成法。

精制方法：易含的杂质是游离的甲酸和甲醇。精制时，加无水碳酸钾干燥后蒸馏，或者加五氧化二磷，在水浴上于80~90℃分馏。也可以先用浓碳酸钠水溶液洗涤，用固体碳酸钠干燥后，再加五氧化二磷分馏。

7.无水氯化钙、甲酸混合后，冷却搅拌慢慢加入甲醇，回流25h 进行反应：

然后蒸馏得到粗品，用无水碳酸钠干燥去酸性过滤，即得成品。
