Production technology of cyclopentanecarboxylic acid

The invention discloses a production technology of cyclopentanecarboxylic acid, and belongs to the field of chemical synthesis. The production technology comprises the following steps: with epoxycyclopentane as a starting material, performing a reaction on the epoxycyclopentane, carbon dioxide, Mg powder and TMSCl to produce 2-hydroxycyclohexanecarboxylic acid, and then performing catalytic hydrogenation by Pd/C in the presence of an acid to obtain the cyclopentanecarboxylic acid. By the production technology, used raw materials are cheap and easy to obtain, the whole technology is easy and convenient to operate, a catalyst can be recycled repeatedly, and a new idea is provided for synthesis of the cyclopentanecarboxylic acid. 本发明公开了种环戊甲酸的生产工艺,属于化工合成领域。该工艺以环氧环戊烷为起始原料与二氧化碳、Mg粉和TMSCl反应生成2-羟基环己甲酸，然后在酸的存在下经Pd/C催化氢化得到环戊甲酸。本发明所用原料廉价易得，整个工艺操作简便，催化剂可多次回收利用，为环戊甲酸的合成提供了新的思路。
