Abstract
The work is devoted to increase in complexity of use of wood raw materials – one of the most important directions in solution to complying with the modern requirements of rational environmental management and environmental protection.Features of impregnation by bisulfite sulfite cooking acid and regularities of bisulfite delignification of young and ripe fir-tree and birch wood have been investigated. It is shown that young thin wood of both breeds becomes impregnated by bisulfite sulfite cooking acid much quicker, than ripe. The nature of delignification processes for young and ripe wood are identical, however intensity of processes is much lower for young wood...
