Abstract

Method for producing wood cellulose, characterized in that it comprises the top of cooking the wood in an alkaline cooking liquor containing sulfides as active chemical components of liquor, the sulfidity of this liquor consisting of not more than 90% of sodium sulfide and consisting of the rest of this sulphidity of organic compounds sulfurized with bivalent sulfur and having a chemical formula selected from the group consisting of: (a) R - S - R' (b) R - S - R (c) Rs - SR' (d) A mixture of two or all three (a), (b), and (c), where R is an alkyl radical and R 'is hydrogen or an alkyl radical equal to or different from R.
