Dithymol-di-iodid, popularly known as aristol, is obtained by the condensation of two molecules of thymol and the introduction of two atoms of iodin into the phenolic groups of the thymol.
Properties : Thymol iodid contains, when dried over sulphuric acid, 45 per cent, of iodin. It occurs as a bright, chocolate-colored, or reddish-yellow, bulky powder, with a very slight aromatic odor. It is practically insoluble in water and nearly insoluble in alcohol.
Action and Uses: Thymol iodid, or aristol, is antiseptic and is used in place of iodoform, chiefly as a dusting-powder. It is inferior to iodoform in antiseptic action and experience with it has been disappointing.
