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.
