巴豆醛即2-丁烯醛,广泛分布于自然环境中,某些有机物燃烧可产生大量巴豆醛,其也可在体内经脂质代谢合成~([1-2])。巴豆醛是一种重要的有机合成中间体,广泛用于合成各类生产、生活用品如食品防腐剂(如山梨酸)、选矿用发泡剂和橡胶抗氧化剂等。巴豆醛为无色或略带黄色的液体,露置于空气中或遇光时 Crotonaldehyde, 2-butenal, is widely distributed in the natural environment. Some organic compounds can generate a large amount of crotonaldehyde when burned. It can also be synthesized in the body through lipid metabolism (1-2). Crotonaldehyde is an important organic synthesis intermediates, widely used in the synthesis of various types of production, household items such as food preservatives (such as sorbic acid), mineral processing foam and rubber antioxidants. Crotonaldehyde is a colorless or slightly yellow liquid that is exposed to the air or exposed to light
