STUDIES ON LIGNIN AND RELATED COMPOUNDS: XIV. THE ACTION OF LEAD TETRA-ACETATE AND OF MERCURIC ACETATE ON GLYCOL LIGNIN DERIVATIVES: (Preliminary communication)

Abstract

Fully methylated glycol lignin (OCH3, 30.4%) was treated with lead tetra-acetate and with mercuric acetate. In the first case the acetoxyl group was introduced to the extent of 11.5%. With mercuric acetate in alcohol, the sole reaction was the substitution of hydrogen by the —HgOCOCH3 group, there being no addition of ethoxyl nor loss of methoxyl groups. After repeated mercurization the final product contained 42.7% of mercury, that is, a ratio of introduced mercury atoms to original methoxyl groups of 1:1.
