'''庚酸'''，又稱'''葡萄花酸'''，是七个[[碳]]的直链[[羧酸]]，结构式CH<sub>3</sub>(CH<sub>2</sub>)<sub>5</sub>COOH。

==性质==
无色具腐败脂肪气味的透明油状液体。微溶于水，溶于[[乙醇]]和[[乙醚]]。

==制备==
[[1-己烯]]与[[合成气]]经[[羰基化]]得到[[庚醛]]，后者再经空气氧化得到庚酸。
:<math>\ CH_3(CH_2)_3CH\!=\!CH_2+CO+H_2\rightarrow CH_3(CH_2)_4CH_2CHO</math>
:<math>\ CH_3(CH_2)_4CH_2CHO +\tfrac{1}{2} O_2\rightarrow CH_3(CH_2)_4CH_2COOH</math>

==用途==
用于生产庚酸[[酯]]类，用作香料的制取原料。

==危害==
庚酸具有腐蚀性，也具有毒性。<ref>{{Cite web |title=Heptanoic Acid - Pubchem |url=https://pubchem.ncbi.nlm.nih.gov/compound/Heptanoic-acid |access-date=2024-07-20 |archive-date=2024-08-15 |archive-url=https://web.archive.org/web/20240815082045/https://pubchem.ncbi.nlm.nih.gov/compound/Heptanoic-Acid |dead-url=no }}</ref>
