摘要
以苯酚和苯乙烯为原料，以草酸和活性白土为混合催化剂合成了苯乙基苯酚。对催化剂用量、配比、反应温度和投料顺序对产物收率的影响加以讨论，得到反应最佳条件。实验结果表明，该工艺反应条件温和，无废酸，无设备腐蚀，苯乙基苯酚收率达９９．３％，并与以浓硫酸为催化剂反应作了比较。
The second generation of the Chinese Architects have linked the national conditions,and have tried to seek the creative road of Chinese modern architecture.During the past years,they have formed the bright creative thinking:the spirit of blazing new trails based on tradition,wholly coordinative sense of environment,the sense value based on humanism and the unadorned and realistic sense of economics.
