Description

Technical field

[0001] The invention belongs to the technical field of dyes, and specifically relates to an anthraquinone solvent dye and its preparation and application. Background technique

[0002] The high-end solvent dyes CI Solvent Blue 104 [116-75-6] and CI Solvent Blue 97 [61969-44-6], which were successfully developed and commercialized by Bayer Company in Germany in the early years, have bright, transparent blue and good heat stability. And light fastness, suitable for the coloring of thermoplastics (hard plastics). This type of dye consists of 2,4,6-trimethylaniline, 2,4,6-triethylaniline (or 2,6-diethyl-p-toluidine) and 1,4-dihydroxyanthraquinone respectively. Condensation reaction is obtained. However, due to the high price of 2,4,6-trimethylaniline and 2,4,6-triethylaniline (or 2,6-diethyl-p-toluidine), the price of this type of dye is expensive. Its application has been limited to a certain extent.

[0003] On the other hand, we have found that some industrial wast...
