Insights into the chemical composition, industrial utility, and international market movement of C.I. Solvent Blue 36.
Solvent Blue 36 (CAS Number: 14233-37-5, Color Index Generic Name: C.I. Solvent Blue 36) is an anthraquinone-based solvent dye. It features exceptional optical properties and strong chemical compatibility, making it indispensable in high-performance polymer coloration. This synthetic dye is characterized by its bright blue hue and excellent thermal stability, allowing it to withstand the rigorous temperatures of modern engineering plastic processing without thermal degradation.
Known chemically as 1,4-bis(isopropylamino)anthraquinone, the molecular structure features a highly conjugated anthraquinone nucleus substituted with isopropylamino branches. These alkylamino groups enhance its solubility in organic solvents, acrylic resins, and various hydrocarbon structures, while the anthraquinone core ensures robust photolytic and thermal resilience.

The production and distribution of C.I. Solvent Blue 36 are highly concentrated within top-tier chemical manufacturing zones in the Asia-Pacific region, with Tianjin, China leading the export volume. Industrial demand is split between primary polymer production and secondary compound processing.
In North America and Europe, stringent regulatory frameworks like EPA TSCA and EU REACH dictate that import batches must be certified free of restricted heavy metal impurities and polychlorinated biphenyls (PCBs). Thus, leading OEMs must leverage high-purity synthesis lines to guarantee clean compliance.
The manufacturing roadmap of Solvent Blue 36 at Sunrise involves the condensation of 1,4-dihydroxyanthraquinone (quinizarin) and 1,4-dihydroxyanthraquinone leuco compound with isopropylamine in an aqueous or organic reaction medium, followed by oxidation, filtration, washing, and drying.
A primary challenge for OEM manufacturers is preventing the accumulation of insoluble residues, unreacted amines, and heavy metals. Standard commercial grades often contain trace amounts of free primary amines which can cause gas-emission bubbles during high-temperature injection molding. Our high-precision filtration and recrystallization techniques yield a premium, ultra-fine grade with ash content < 0.2% and moisture content < 0.5%.
Our processing standard supports custom blending, liquid-dissolved formulations, and pre-dispersed masterbatches to minimize dust pollution in our clients' manufacturing plants.
Global environmental guidelines demand clean, eco-friendly colorant alternatives. Solvent-based dyes face scrutiny due to VOCs and potential hazardous discharges during syntheses. By integrating modern closed-loop recycling systems and strict wastewater treatment, we align our production lines with ZDHC Level 3 and GOTS certification, paving the way for sustainable industrial coloring.
