[0012] Synthetic steps:

[0013] (1) Add 0.4mol 2-n-butyl-4-bromotoluene and 14.4g benzoyl peroxide in the reaction flask equipped with mechanical stirring and reflux condenser, after stirring and heating to reflux, 71.2g (0.4mol ) 2-bromo-2,5-diketone pyrrole (NBS) was added to the reaction flask in batches within 20 minutes, heated to reflux for 2 hours, and the reaction yield was 65% (GC). The reaction solution was neutralized with sodium carbonate, concentrated, dissolved with industrial absolute ethanol (1g: 1mL) under reflux, cooled to -15°C for recrystallization, the purity was about 90% (GC). Its purity was >99% after multiple recrystallizations.

[0014] (2) Under the protection of nitrogen, add 0.05mol triphenylamine and 100mL DMF to the reaction flask equipped with mechanical stirring and reflux condenser, cool to 5°C in an ice bath, slowly add 0.1mol phosphorus oxychloride dropwise under stirring, dropwise add Upon completion, the ice bath was removed and allowed...

Abstract

The invention relates to a compound used for a polyester fabric dye as shown in a formula I (which is shown in the description).

Description

technical field [0001] The invention belongs to disperse dyes and the application of the dyes in the dyeing and printing of polyester fibers and blended materials. Background technique [0002] Disperse dyes are a kind of non-ionic dyes with simple structure and low water solubility, which mainly exist in the dispersed state of tiny particles in the dye bath. It came out as early as the early 1920s. It was mainly used in the dyeing of acetate fiber at that time, so it was also called acetate fiber dye. In recent years, with the rapid development of synthetic fibers, especially polyester fibers, disperse dyes have gradually become one of the fastest-growing dyes in modern times. At present, it is mainly used for dyeing and printing of polyester fiber, and it can also be used for dyeing of hydrophobic textile materials such as acetate fiber and polyamide fiber. With the improvement of people's living standards, consumers have higher and higher requirements for the wearing pe...
