    摘要: A process for the production of 2-benzyl fatty acids and esters thereof corresponding to the following formula ##STR1## comprising reacting 2-fatty alkyl-4,4-dimethyl-2-oxazolines with benzaldehydes corresponding to the formula R.sup.2 --C.sub.6 H.sub.4 --CHO to form 2-(1-benzylidene)-fatty alkyl-4,4-dimethyl-2-oxazolines, catalytically hydrogenating the products of this reaction to the 2-(1-benzyl)-fatty alkyl-4,4-dimethyl oxazolines and converting the products thus formed by acid-catalyzed hydrolysis or solvolysis with an alcohol of the formula R.sup.5 OH into the 2-benzyl fatty acids or esters thereof. Amidosulfonic acid gives particularly high yields as catalyst for the reaction of the 2-fatty alkyl-4,4-dimethyl-2-oxazolines with the benzaldehydes.
