Huangshan Pumi Te New Materials Co., Ltd. has developed a series of environmentally friendly dyes Reactex, three varieties of high-end series of 20 reactive dyes products meet EU standards, improve the domestic dyes in the high-end market share.

The project is an international scientific and technological cooperation projects in Anhui Province, Pu Mite company through cooperation with foreign companies, made a number of results: First, double-azo dyes in the country the first choice as a design model, using 2,5 - dimethyl aniline and peri acid, respectively, instead of Kerry cefoxitin and N-methyl aniline, designed to meet the EU requirements of high-grade structure of reactive dye molecules; the second is a single azo chromophore and a mixture of sodium nitrite and hydrochloric acid while adding a certain percentage of ice water in a second anti-diazo new process, the reaction is instantaneous, increase the yield of diazo, almost no by-products generated. In addition, they will dye synthetic membrane separation technology for reaction and product separation and purification unit to replace the traditional production process of salting the separation process, an effective solution to the high salinity water pollution problems.
