    摘要： A continuous process for efficiently co-producing secondary alcohols of long-chain olefins and lower carboxylic acid esters, comprising (I) performing an acid/olefin reaction in the presence of a heterogeneous catalyst such as Amberlyst 15, and (II) performing an ester-exchange reaction in the presence of, e.g., titanium alcoholate. A desirable feature of the process is the ability to produce co-products of choice.
