摘要：
A method for phosphorylation of technical lignins and their derivatives by the action of thiophosphoryl chloride on air-dried sodium lignates over 5-30 min with vigorous stirring and simultaneous grinding in a solvent-free vibrating reactor at 20-80 A degrees C followed by alkali-metal alkoxides with vigorous stirring and simultaneous grinding for 10-40 min at the same temperature and a 1:1 mole ratio of phosphorylating reagents calculated per mole of lignin OH groups was developed.
