Abstract

The work is a continuation of the preceding study of possibilities for preparation of labelled derivatives of fluorescein. The conditions under which it is possible to get maximum possible yield of individual products from reaction mixture of mercuric acetate‐^203^Hg and fluorescein has been studied in detail. It has been found that the yield of derivatives with different mercury content depends to a great extent on the molar ratio of both reaction components. In the first, rapid step of mercurization approximately the same amount of all products is formed regardless of the molar ratio of reaction components. By heating the equilibrium is shifted in favour of the product corresponding to the given molar composition of reaction mixture. The detailed procedures for preparation of difluoresceinyl mercury‐^203^Hg and hydroxymercurifluorescein‐^203^Hg have been given.
