straight alkyl chain of at least 16 carbons may be particularly useful in producing softer less adherent pulp with better hand for tissue and fluff pulp uses the substitution of one counter cation for another will be readily accomplished by one of skill in the art employing known standard techniques cation exchange employing known cation exchange resins is a particularly convenient method in addition to the kraft and soda pulping processes mentioned above the term standard alkaline pulping processes comprehends all those known pulping processes which are conducted or which are initiated at ph values greater than 7 illustrative of these processes are such methods as soda oxygen neutral sulfite semichemical alkaline sulfite polysulfide bisulfite alkaline sulfite and sulfonated chemimechanical it will also be obvious to one of skill in the art that the use or the non use of anthraquinone anthrahydroquinone and all related compounds well known in the recent literature in such standard alkaline pulping processes are also both comprehended by the invention the following examples further illustrate the best mode contemplated by the inventor for the practice of his invention the initial series of examples illustrate the use of monoperoxysulfate in the pretreatment of wood prior to chemical pulping a series of samples of northern softwood chips having an average moisture content of 15 are treated by immersion in aqueous solutions of oxone at varying weight concentrations relative to the oven dry weight of the wood at varying times and temperatures wood chips 425 g are immersed in liquor containing khso 5 42 5 g at a liquor to wood ratio of 7 6 to 1 0 at 20 u00b0 c for 72 hours the chips are then drained washed and soda pulped cooking conditions are 22 naoh 70 minutes to 170 u00b0 c 90 minutes at.
