一般描述

丙酸(PA)也被叫做初油酸,是一种短链脂肪酸,主要用于食品防腐剂。它是未消化的食物在直肠中被微生物发酵产生的主要代谢末端产物之一。它可以用Propionibacterium acidipropionici甘油/葡萄糖共发酵来生产。晶体结构研究表明PA晶体是单斜晶体,有空间基团P21/c
丙酸(PA)是一种天然羧酸,它的天然状态是一种无色腐蚀液体,有难闻的气味。它易混合于水。工业上在羰基镍作为催化剂存在情况下,乙烯氢羧基化生成丙酸。PA被发现能够降低食物摄入,降低血浆和肝脏中的脂肪酸,提高组织胰岛素灵敏度,抑制免疫反应。丙酸是一种良好的原材料,它稳定,便宜,安全,可以用作食品添加剂。

应用

丙酸可以用来改变石灰石,提高它吸收CO2的能力。
