Abstract

Surfactants were used in the pulping of Kraft hardwood chips in an attempt to decrease cooking time while attaining ·the same Kappa Number. It was found that surfactants could not be used to decrease cooking time, but anthraquinone and nonylphenol could be used to increase both yield and bond strength.Dimethylamides and quaternary ammonium salt surfactants were found to be detrimental to the pulping of hardwood resulting in hard uncooked chips
