Embodiment Construction

[0018] 1. New asymmetric fluorescent whitening agent

[0019] According to whether the triazine rings at both ends are the same, triazine-based aminostilbene fluorescent whitening agents can be divided into two types: symmetrical and asymmetrical structures. Traditional fluorescent whitening agents have symmetrical structures; asymmetric structure fluorescent whitening agents have performance Special, there are few literature reports, and there are no applicable products at home and abroad.

[0020] In the present invention, a novel asymmetric fluorescent whitening agent is synthesized in the following manner.

[0021] 1)R 1 H and R 2 H uses p-aminobenzenesulfonic acid, R 4 H adopts diethanolamine, while R 3 H is selected from diethylamine and ethanolamine;

[0022] 2) using ANSD acid to react step by step with the different disubstituted triazine rings formed;

[0023] 3) design a new synthetic route, i.e. cyanuric chloride is first combined with R 1 H(R 2 H) carry ou...

Abstract

The related synthesis technique for environment-protective triazinylamino diphenyl ethylene fluorescer in paper-making, paint and ink comprises: with ANSD acid as initial reactant, composing asymmetric fluorescer; designing a new synthesis path for the composite mixed and quaternary fluorescers; solves the pollution problem basically, and spreads application range. Wherein, the substituents of R1 and R2 are independent amino acid residues with hydrogen atoms on amido removed, such as, the aminobenzenesulfonic residue (I) and o-aminobenzenesulfonic residue (II); the R3 and R4 are independent alkamine residues or aminoalkyl residues with hydrogen atoms on amido removed, such as, morpholinyl(III), phenylamimo(IV), diethanolamimo(-N(CH2CH2OH)2), diacetylamino(-N(C2H5)2), ethanolamimo(-NCH2CH3OH), triethanolamimocation(V), triethylaminocation(VI).

Description

technical field [0001] The present invention relates to the technical field of fine chemicals, in particular to high-efficiency and environment-friendly triazine-based aminostilbene fluorescent whitening agents. This series of high-efficiency and environment-friendly fluorescent whitening agents includes asymmetric fluorescent whitening agents, mixed fluorescent whitening agents Agent and quaternary ammonium salt type fluorescent whitening agent, mainly used for whitening of papermaking, textile, ink and paint. Background technique [0002] Triazinyl aminostilbene fluorescent whitening agents are widely used in papermaking, textiles, coatings, detergents and other industries because of their high cost performance. Although the traditional production process of powder fluorescent whitening agent, such as the representative VBL, has good cellulose affinity and good whitening performance, it also shows increasingly serious drawbacks. First, one of its synthetic raw materials, ...
