<p>Lower alcohol esters of fatty acids are produced by esterifying free fatty acids of unrefined fats with a lower alcohol in an amount larger than its solubility in the fats in the presence an acid catalyst; separating the product mixture into the fat layer and the lower alcohol layer, so that the latter may be removed out; and then effecting the interesterification reaction between the resulting, refined fats and a lower alcohol with an alkali catalyst.</p> |
