The Weak Base Anion Exchange Resin D301SC is a premium-grade industrial resin engineered for high-efficiency separation and purification. Featuring a polystyrene structure crosslinked with divinylbenzene and a tertiary amine functional group, this resin is specifically designed for the removal of strong mineral acids and the purification of organic matter in demanding chemical environments.
Optimized for versatility, D301SC excels in sugar decolorization, wastewater treatment, and the refinement of organic substances. Its superior exchange capacity and robust mechanical stability ensure consistent performance across various operational temperatures, making it a reliable alternative to industry standards like Purolite A100 and Dowex 66.
| Appearance | Opalescent to light yellow opaque spherical beads | Polymer Structure | Polystyrene crosslinked with divinylbenzene |
|---|---|---|---|
| Functional Group | -N(CH3)2 | Ionic Form | Free amine |
| Weight Exchange Capacity | ≥4.8 mmol/g | Volume Exchange Capacity | ≥1.45 mmol/ml |
| Real Density | 1.03~1.06 g/ml | Bulk Density | 0.65~0.72 g/ml |
| Water Retention | 48%~58% | Particle Size Range | 0.315~0.63 mm (≥95%) |
Boasting a weight exchange capacity of ≥4.8mmol/g, ensuring maximum ion capture and reduced regeneration frequency.
Designed to withstand maximum operating temperatures up to 120℃, ideal for high-temperature industrial processes.
A whole bead count of ≥95% and low uniformity coefficient (≤1.40) minimize pressure drops in the resin column.
Optimized for quick desorption using HCl and NaOH, reducing downtime and chemical consumption during cycling.
Perfectly suited for sugar decolorizing, refined organic matter recovery, and complex wastewater treatment.
A high-performance equivalent to Purolite A100, Dowex 66, and Amberlite IRA-93 for seamless integration.
Must be stored in a wet state above 0℃ to maintain structural integrity and functional activity.
Utilize closed containers or 5% salt water solutions to prevent dehydration and bio-growth.
Implement flocculation or sand filtration to prevent suspended solids from jamming resin pores.
Recommended alkali-water-acid-water sequence for processing to maximize ion exchange efficiency.
Account for transformation expansion rates during column setup to prevent resin overflow.
Use wet packing or back-flushing techniques to remove internal bubbles and ensure uniform flow.
| Performance Metric | Standard Resins | D301SC Resin |
|---|---|---|
| Operating Temp | Up to 60-80℃ | Up to 120℃ |
| Regeneration Speed | Slow/Moderate | Fast (1-2 BV/h) |
| Bead Integrity | Variable | High (≥95% Whole) |
| Exchange Capacity | Average | Superior (≥4.8 mmol/g) |
| Lifespan | Moderate | Extended (High Stability) |
It is primarily used for the removal of strong mineral acids, sugar decolorization, and the purification of refined organic substances in industrial wastewater and chemical processing.
Resin should be kept in a wet state at temperatures above 0℃. For long-term storage, use a closed space or a salt water solution of 5% or higher.
The resin is regenerated using 3-5% HCl (Hydrochloric Acid) and 2-4% NaOH (Sodium Hydroxide) to restore its functional capacity.
Yes, the D301SC resin is designed for high thermal stability, with a maximum operating temperature of 120℃.
Steps like flocculation or sand filtration are critical to remove suspended solids that could jam the resin pores, which would otherwise reduce flow rates and efficiency.
D301SC offers comparable or superior exchange capacities and thermal stability to industry benchmarks like Purolite A100 and Dowex 66, providing a cost-effective, high-performance alternative.
