A method of producing dicarboxylic acids (e.g., α,ω dicarboxylic acids) by reacting a compound having a terminal COOH (e.g., unsaturated fatty acid such as oleic acid) and containing at least one carbon-carbon double bond with a second generation Grubbs catalyst in the absence of solvent to produce dicarboxylic acids. The method is conducted in an inert atmosphere (e.g., argon, nitrogen). The process also works well with mixed unsaturated fatty acids obtained from soybean, rapeseed, tall, and linseed oils.
一种生产二羧酸(例如,α,ω-二羧酸)的方法,通过将具有末端COOH的化合物(例如,不饱和脂肪酸如油酸)与至少含有一个碳-碳双键的第二代Grubbs催化剂在无溶剂的情况下反应,以产生二羧酸。该方法在惰性气氛(例如,氩气、氮气)中进行。此过程也适用于从大豆、油菜籽、海藻和亚麻籽油中获得的混合不饱和脂肪酸。
