Deinking agent for regenerating waste paper. |
摘要 |
<p>A deinking agent for regenerating waste paper, which comprises a reaction product obtained by reacting a compound having an OH group, which is represented by the following (A) or (B) with a dicarboxylic acid or an anhydride thereof as an active ingredient: (A) a compound obtained by adding ethylene oxide and propylene oxide to a higher fatty acid having 8 to 22 carbon atoms in such a manner as to control the molar ratio of ethylene oxide/propylene oxide to from 1 to 4 and to control the total amount of the added ethylene oxide and propylene oxide to from 10 to 50 moles on average; or (B) an incomplete ester of a polyhydric alcohol, to which ethylene oxide and propylene oxide have been added in such a manner as to control the molar ratio of ethylene oxide/propylene oxide to from 1 to 4 and to control the total amount of the added ethylene oxide and propylene oxide to from 10 to 50 moles per OH group on average, and a higher fatty acid having 8 to 22 carbon atoms; is disclosed. With the use of this deinking agent, a deinked pulp having a high degree of whiteness and a small residual ink number can be obtained. l</p> |
