摘要： The present invention aims at developing a deinking method applicable to the deinking of, for example, waste OA (office automation) paper and telephone directories, whereby a deinked pulp having a high whiteness and little contamination with large ink spots and unliberated ink can be obtained. The object of the present invention can be achieved by deinking, for example, waste OA paper or telephone directories by using a deinking composition containing as an effective component a reaction mixture (III) obtained by conducting the addition reaction of ethylene oxide and propylene oxide with a mixture (I) comprising a fat and oil (a) and a mono- to hexahydric alcohol (b) and/or with a transesterification mixture (II) obtained by conducting the transesterification reaction of a fat and oil (a) with a mono- to hexahydric alcohol (b), in such a manner that the molar ratio of ethylene oxide to propylene oxide which are used as starting materials ranges from 0.8 to 1.2 and that the molar number of ethylene oxide which is used for the addition reaction ranges from 50 to 100 mol per mole of the fat and oil (a).
摘要翻译：本发明旨在开发适用于例如废弃OA（办公室自动化）纸和电话簿的脱墨的脱墨方法，由此可以获得具有高白度和少量污染的脱墨纸浆，并且可以获得大的墨点和未起泡的油墨。本发明的目的可以通过使用含有作为有效成分的脱墨组合物来脱墨，例如废纸OA或电话簿，通过进行环氧乙烷和环氧丙烷的加成反应获得的反应混合物（III）包含脂肪和油（a）和一至六元醇（b）的混合物（I）和/或通过脂肪和油（a）与单体（a）进行酯交换反应而获得的酯交换混合物（II） - 以六元醇（b）的形式，使用作为原料的环氧乙烷与环氧丙烷的摩尔比为0.8〜1.2，加成反应所用的环氧乙烷的摩尔数为每摩尔脂肪和油（a）为50-100摩尔。
