Summarized the research advances in preparation of 3 -methylpyridine from acrolein. Formaldehyde, acetaldehyde, propionaldehyde or acetone and acrolein can synthesize 3 -methylpyridine with ammonia and catalysts. Property of catalysts and separation and purification of products have been did immense amounts of concrete research. It was suggested that the acrolein route played an important role in increasing selectivity of 3 -methylpyridine and the key problem was how to solve the self- aggregation of acrolein.%综述了以丙烯醛为原料制备3-甲基吡啶的研究进展。有氨和催化剂存在的条件下，甲醛、乙醛、丙醛或丙酮均可以和丙烯醛发生反应生成3-甲基吡啶。研究人员对催化剂的性能和产物的分离提纯做了大量的实验。本文认为采用丙烯醛路线对于提高反应选择性具有重要作用，指出该路线的关键问题是解决其自身聚合问题。
