✦ Synopsis

Chromotropic acid, disodium salt, reacts with an excess amount of formaldehyde in water to give a dark red plastic-like water-soluble cyclic tetrameric compound.

Water-soluble synthetic macrocyclic compounds have been the focus of. interest of many chemists in recent years.

l-3 We report in this paper a water-soluble cyclic tetrameric compound prepared by reacting chromotropic acid, discdium salt, with an excess amount of formaldehyde.

An aqueous solution containing chromotropic acid, disodium salt, and an excess of formaldehyde
