Clean synthesis of disperse azo dyes based on peculiar stable 2,6-dibromo-4-nitrophenyl diazonium sulfate

The development of clean synthetic technology of disperse azo dyes is essential for the dye industry due to ecological and economical demands. In this study, a clean, safe, and low-energy-consumption method for preparing disperse azo dyes based on 2,6-dibromo-4-nitroaniline is presented with excellent yield and short reaction time. The peculiar stable diazonium sulfate of 2,6-dibromo-4-nitroaniline is precipitated from the organic reaction system, and the solid diazonium salt is directly used to synthesize disperse azo dyes. Compared with traditional method, the amount of sulfuric acid used is reduced by 80%, the amount of waste inorganic salt is reduced by 80.9% and the heat released from the reaction system is reduced by 88.5% in the proposed method. The dye structures are verified by 1H NMR, 13C NMR, Fourier transform infrared spectroscopy (FT-IR), and high resolution mass spectrometry (HR-MS). Compared with commercial dyes, the prepared dyes have the same dyeing properties that are sufficient for industrial applications.

Diazotization method of wet nitroaniline

The invention provides a diazotization method of wet nitroaniline, and relates to the field of dye synthesis. The diazotization method comprises following steps: step one, evenly stirring sulfuric acid (98%) and nitrosyl sulfuric acid (40%) in a diazotization reactor; and step two, adding wet nitroaniline into the diazotization reactor at a controlled temperature of -10 to 40 DEG C to obtain diazotization salts, wherein the mole ratio of sulfuric acid to nitrosyl sulfuric acid to diazotization component is 1.0-6: 1.02-1.1: 1. The quality of the provided wet dye is the same as that of a dry product, the diazotization component does not need to be dried, and the provided dye is energy saving and environmentally friendly.

Disperse dye composition and preparation method and application thereof

The invention relates to a disperse dye composition and a preparation method and application thereof. The disperse dye composition comprises a component A as shown in formula (1), a forbidden aromatic amine compound, chlorinated phenol, chlorobenzene, chlorotoluene, any auxiliary materials and other unavoidable impurities. According to the disperse dye composition, the total content of the forbidden aromatic amine compound is 10ppm or lower, the total content of each chlorinated phenol is 0.5ppm or lower, and the total content of chlorobenzene and chlorotoluene (COCs) is 1ppm or lower. Various environment-protective indexes of the disperse dye composition conform to the requirement of Oeko-Tex Standard 100 (2016), and various performance such as the fold strength, sublimation fastness and the like is excellent. Furthermore, after the disperse dye composition of the invention is used for dyeing a fabric, the dyed fabric conforms to the requirements of a baby level of the Oeko-Tex Standard 100 (2016). (Shown in the description).
