Process for the production of fatty acids by oxidative dehydrogenation of straight or branch chain primary alcohols of from C-4 to C-30 chain lengths per molecule, or mixtures of branch and straight chains, which are selectively reacted with an anhydrous alkali metal hydroxide. In the reaction, the temperature of reaction is gradually increased to maintain the reaction medium in a liquid non-viscous state. The reaction temperature is, however, maintained at a sufficiently low temperature to minimize by-product formation. The process is conducted at temperatures of from about 175°C to about 400°C for sufficient time to form the sodium salt of the acid which is then converted to the acid utilizing a mineral acid.

金属氢氧化物反应。在反应过程中,反应温度逐渐升高,以保持反应介质处于液态非粘性状态。不过,反应温度要保持在足够低的温度,以尽量减少副产品的形成。该工艺在约 175°C 至约 400°C 的温度下进行足够长的时间,以形成酸的钠盐,然后利用矿物酸将其转化为酸。
