Activated carbon catalyst support for glyphosate herbicide production PURESTAR manufactures specialized activated carbon catalyst supports for glyphosate (N-phosphonomethylglycine) synthesis via the IDA (iminodiacetic acid) and DEA (diethanolamine) routes. Our catalyst carbon features:
High surface area (> 1,000 m²/g) for optimal noble metal dispersion (Pd, Pt, Ru)
Controlled pore architecture – balanced micro/mesopore ratio for reactant accessibility and product diffusion
Exceptional mechanical strength – withstands fluidized bed and slurry reactor conditions
Low ash and sulfur content – preventing catalyst poisoning and side reactions
Our glyphosate catalyst supports have been validated by leading agrochemical manufacturers for oxidation, hydrogenation, and phosphonomethylation steps, delivering consistent conversion rates and extended catalyst life.
2.Chemical Purification
Fine chemical and electronic-grade chemical manufacturers have strict requirements for trace impurity control in process streams. PURESTAR's acid-washed activated carbon is specially engineered for high-purity chemical purification scenarios. Our low-ash activated carbon (< 5% ash content) effectively removes:
Trace organic impurities and color bodies
Catalyst residues from chemical synthesis processes
Particulate contaminants that affect product purity
It ensures minimal contamination of high-purity acids, solvents, and chemical intermediates, meeting the strict quality standards of electronic and fine chemical industries.
3.Base Oil Filtration
Lubricant re-refineries and base oil producers require high-performance purification for Group I, II, and III base stocks.
PURESTAR activated carbon provides comprehensive solutions for color removal, odor reduction, and antioxidant stabilization. Our carbon efficiently removes harmful substances affecting oil quality:
Oxidation byproducts and sludge precursors
Polycyclic aromatic hydrocarbons (PAHs)
Sulfur and nitrogen compounds that reduce oil stability
4.Preventing Dye Migration
In food packaging and textile applications, dye migration is a critical quality and safety concern.PURESTAR activated carbon is integrated into barrier layers and absorbent pads to solve this pain point. Its high adsorption capacity for dye molecules:
Prevents color migration from packaging materials into food products
Avoids cross-coloring between fabric layers during storage and transport
Meets food contact material safety standards: non-toxic, odorless, no secondary contamination
Suitable for flexible packaging, food-grade paper, and textile dye fixation auxiliary applications.
