Abstract: This paper reviewed the synthesis of 3-picoline via the reaction between acrolein and ammonia. It was reported up to now that there are mainly three approaches for the synthesis of 3-picoline from the reaction of acrolein with ammonia，i.e.，the liquid-phase reaction in stirring tank reactor，the gas-phase reaction in fixed-bed reactor and the gas-phase reaction in fluidized-bed reactor. The paper described the general features of these reaction processes，with comments on their advantages and disadvantages and the related catalysts. It addressed particularly the key issues in the reaction process of acrolein/ammonia to 3-picoline. The foreground of the mesoporous material and solid acid catalysts applied to the reaction and the mechanism researches of 3-picoline prepared from acrolein were also prospected，the mesoporous material and solid acid catalysts applied to the reaction and the mechanism researches were thought to one of the development direction.
