| titleOfInvention | Deinking method |
| abstract | ABSTRACT The present invention aims at developing a deinking method applicable to the deinking of, for example, waste OA 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 trans-esterification 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). |
