利用廉价、无毒的催化剂在水中将CO2高效转化为高附加值的化学品是绿色化学中一个非常有吸引力的课题。本文研究了在水溶液中，氢氧化胆碱促进CO_2和2-氨基苯甲腈转化为喹唑啉-2，4（1H，3 H）-二酮的反应。考察了反应温度、压力、反应时间、催化剂用量等因素对反应的影响，优化了反应条件。结果表明，氢氧化胆碱作为一种可生物降解、环境友好、绿色、廉价的材料，对该反应具有超常的催化活性。并对反应机理进行了探讨。
The efficient conversion of CO2 to high value-added chemicals in water with cheap and non-toxic catalysts is a very attractive topic in green chemistry. In this work, the transformation of CO2 and 2-aminobenzonitriles to quinazoline-2,4(1H,3H)-diones in water promoted by choline hydroxide has been studied. The effect of temperature, pressure, reaction time, and amount of catalyst on the reaction were investigated and the reaction conditions were optimized. It was demonstrated that choline hydroxide showed supernormal catalytic activity to promote this reaction as a biodegradable, environmentally friendly, green and cheap material showed supernormal catalytic activity to promote this reaction. Furthermore, the reaction mechanism was discussed.
