HE COMPOSITION OF A SPENT SPRUCE SULFITE LIQUOR

摘要

The morphological structure and chemical composition of spruce wood and the reactions of the various constituents during a sulfite cook are outlined in the first two chapters.nAfter a brief description of ion exclusion and previous attempts to fractionate spent sulfite liquor by this method, the fractionation by ion exclusion of spent liquor from an industrial sulfite cook of spruce yielding a strong pulp is described.
