Abstract

하기한 일반식을 갖는 3가지 화합물(I),(Ⅱ),(Ⅲ)의 조성물로서 이들 화합물(I),(Ⅱ),(Ⅲ)의 중량비가(I):(Ⅱ):(Ⅲ)=20∼60:30∼60:10∼50이 되는 고지 재생용 탈묵제로서, 종래의 탈묵제에 비하여 부상법으로 탈묵시에 탈묵 공정에서 적정 기포를 발생시키고, 탈묵펄프의 백색도를 향상시키며, 초지 공정에서의 기포발생을 최소화함으로써 양질의 재생펄프를 제조할 수 있고 작업효율도 향상시킬 수 있다.As a composition of three compounds (I), (II) and (III) having the following general formula, the weight ratio of these compounds (I), (II) and (III) is (I) :( II) :( III) It is a deoiling agent for reclaiming waste paper of 20 to 60:30 to 60: 10 to 50, and it is possible to generate an appropriate bubble in the deinking process at the time of deinking by the flotation method as compared with the conventional deinking agent, and improve the whiteness of the deinking pulp. By minimizing bubble generation in the papermaking process, high-quality recycled pulp can be produced and work efficiency can be improved.

Claims

Compositions of three compounds (I), (II) and (III) having the following general formula wherein the weight ratio of compounds (I), (II) and (III) is (I) :( II) :( III) = 20-60: 30-60: 10-50, the deodorant for recycling paper used.

(I) R ₁ COO (C ₂ H ₄ O) _k (C ₃ H ₆ O) _l H

(II) R ₂ COO (C ₂ H ₄ O) _m (C ₃ H ₆ O) _n H

(III) R ₃ COO (C ₂ H ₄ O) _p (C ₃ H ₆ O) _q H

(Wherein R ₁ and R ₂ are each an alkyl group having 11 to 17 carbon atoms, R ₃ is an alkyl group having 13 to 17 carbon atoms, and k, m, and p are integers of 10 to 25, respectively, L, n and q are respectively) It is an integer of 3 to 13, and k: l, m: n, and p: q are each in the range of 2: 1 to 3: 1)

The weight ratio of compounds (I), (II) and (III) is compound (I) :( II) :( III) = 24 to 40:35 to 50:25 to 40. Deodorant for recycling waste paper.

As a composition of three compounds (I), (II) and (III) having the following general formula, the weight ratio of compounds (I), (II) and (III) is (I) :( II) :( III) = A waste paper deinking method using a waste paper recycling agent which is 20 to 60:30 to 60: 10 to 50, characterized by adding 0.10 to 0.80% by weight to the weight of the raw material waste paper. Notice the deconstruction method.
