羟基处于醛基邻位和对位的苯甲醛与几种苯乙酮衍生物的缩合，多数没有得到预期的产物，或收率极低；苯乙酮环上的羟基对缩合反应影响很大，羟基越多，缩合越困难。
The groups in ring of benzaldehydes, no matter they are electron withdrowing or electron donating except of hydroxy, do not seem to have much effect on the yield.
研究了在稀碱催化下邻羟基苯乙酮和苯甲醛在乙醇溶液中的羟醛缩合反应，溶剂可以循环使用，适合工业化生产。
During the condensation reaction, the feedstock remaining after reaction can be recycled, and this synthesis route was suitable for the commercial production.
