This paperindicated that it was good for condensation reaction when benzene-ring bearingelectron-attaching groups. It also showed that and the 6-hydroxyl group could bereacted with acyl halide, haloid ether and halo alkene, but not with halo alkane. It wasnot only the first time to find that the reaction product of D-mannitol and aromaticaldehyde is tri-condensation derivatives, but also the first time to obtain thep-phthaldehyde-sorbitol derivatives containing eight hydroxyl groups.

研究发现：苯环上有吸电子基团时对缩合反应有利；多元醇缩醛衍生物6-羟基除与酰氯反应外，也能和卤代酸酯、溴代烯反应，但不与卤代烷反应；首次发现D-甘露醇与醛反应主要得到三缩合物；首次合成了含有8个羟基的对苯二甲醛和山梨醇的缩合物。
