Introduction

THIS group contains but one product, maclurin, that is of tinctorial value, and this substance has but feeble dyeing properties. Maclurin, however, found considerable commercial use at one time in the form of its dis-azobenzene derivative known as "Patent Fustin".

Besides maclurin, a number of hydroxylated derivatives of benzophenone occur in nature, but they have no tinctorial value. It has, however, been thought advisable to introduce a brief account of the two most important of these, viz. cotoïn and phloretin, in particular, in view of the attempt made by Perkin and Martin (Chem. Soc. Trans., 1897, 1149) to obtain from them products of tinctorial value similar to Patent Fustin".
