    摘要: A deinking agent comprising an ester mixture as the active ingredient, wherein the ester mixture is obtained by adding ethylene oxide and propylene oxide to a mixture obtained by reacting a natural fat or a reaction product, obtained by preliminarily reacting a natural fat with glycerol, with a monohydric or dihydric alcohol in such a manner as to give a molar ratio of the alcohol to the glycerol in the natural fat of from 0.02/1 to 1/1. By using the deinking agent of the present invention, a less sticky deinked pulp can be obtained without any foaming troubles or dulling.

    摘要: A liquid deinking composition comprising (a) a fatty acid mixture containing 40 to 90 weight % of saturated fatty acids having 12 to 14 carbon atoms and less than 60 weight % of saturated fatty acids having 16 to 18 carbon atoms, (b) a nonionic surfactant with HLB of 2 to 12 in a proportion of (a)/(b)=5/95 to 40/60 (weight ratio), and (c) 0 to 20 weight % (based on the composition) of water. No crystals of fatty acids are precipitated at ambient temperatures, and the separation, solidification or precipitation of crystals due to a temperature change is not caused. Further, the handling property is improved because of the liquid form.

    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).
