Abstract: Acrylic acid production has been greatly affected by the increasing shortage of petroleum，and it is particularly important to investigate how to produce acrylic acid from renewable resources. Lactic acid production by fermentation from renewable resources is a mature process，hence，dehydrating lactic acid to acrylic acid might be an effective alternative way for acrylic acid production. This paper provides a review on the main approaches of acrylic acid production with particular focus on the current research situation for lactic acid dehydration methods，prospects for acrylic acid production from lactic acid are also discussed.

摘要： 随着石油资源的日渐短缺，丙烯酸的生产受到了较大影响，如何利用可再生资源生产丙烯酸显得尤为重要。发酵法生产乳酸工艺已经比较成熟，以发酵乳酸为原料脱水转化为丙烯酸成为生产丙烯酸的一种有效途径。本文综述了丙烯酸的主要生产途径，重点是乳酸脱水制备丙烯酸的研究现状，并指出了乳酸制备丙烯酸的发展前景。
