摘要： A floatation method for the regeneration of waste paper employs as a deinking agent a reaction product of an alkylene oxide with a mixture of products obtained by the reaction of a natural oil or fat with an alkanolamine in a mole ratio of the natural oil or fat to the alkanolamine of products is in the range from 1:0.1 to 1:3,, wherein the amount of the alkylene oxide is in the range from 100 parts by weight to 1000 parts by weight based on 100 parts by weight of the mixture of products, provides pulp having higher degree of whiteness and less residual ink and problems caused by pitch than pulp prepared by a corresponding floatation method which employs a conventional deinking agent.
