Polymeric Catalyst Resins (Super-Gel & Macroporous) — Physical & Chemical Specifications
R–SO₃H (Cat.) · Styrene-DVB · Super-Gel & Macroporous · 7 Grades| Grade | Ionic Form | Total Capacity (mmol/g) | Water Retention (%) | Bulk Density (g/mL) | Specific Gravity (g/mL) | Particle Size Range (%) | Whole Bead (Attrition Resistance) (%) | Color | Catalytic Reaction & Technical Specifications | TDS / RFQ |
|---|---|---|---|---|---|---|---|---|---|---|
| 001CH | H⁺ | ≥5 | 55–65 | 0.72–0.78 | 1.18–1.28 | (0.4–1.25 mm) ≥95% | ≥98 | Light yellow | Super-gel strong acid cation resin with very high catalytic activity and selectivity and good mechanical strength; mainly used for Bisphenol A production and ester synthesis or hydrolysis. Dry resin is also available (water retention 3–5%) | |
| 002CH | H⁺ | ≥5 | 75–85 | 0.7–0.78 | 1.15–1.20 | (0.4–1.25 mm) ≥95% | ≥98 | Light yellow | Esterification catalyst for long-chain esters, with high catalytic activity and long service life | |
| 003CH | H⁺ | ≥4.9 | 42–48 | 0.78–0.83 | 1.18–1.26 | (0.4–1.25 mm) ≥95% | ≥98 | Golden yellow to brown | Dedicated solid-acid catalyst for the transesterification of methyl acetate and ethyl acetate | |
| D001CH | H⁺ | ≥4.8 | 50–60 | 0.75–0.80 | 1.22–1.30 | (0.4–1.25 mm) ≥95% | ≥95% | Grey | Mainly used for MTBE and TAME production, with high catalytic activity and selectivity, high mechanical strength and low leachables. Specific surface area 35–45 m²/g, pore volume 0.3–0.4 mL/g, average pore diameter 20–50 nm. Dry resin also available (water retention 3–5%) | |
| D002CH | H⁺ | ≥3 | 45–55 | 0.78–0.88 | 1.28–1.35 | (0.4–1.25 mm) ≥95% | (≥90) | Dark brown to black | Highly thermally stable resin, suitable for long-term service at 180 °C; mainly used as a catalyst for the hydration of olefins to fatty alcohols | |
| D003CH | H⁺ | ≥5.2 | 50–60 | 0.77–0.85 | 1.22–1.30 | (0.4–1.25 mm) ≥95% | (≥90) | Dark brown to black | Over-sulfonated macroporous catalyst resin: compared with D001CH, offers higher exchange capacity (≥5.2 mmol/g) and stronger resistance to fouling | |
| D004CH | H⁺ | ≥5 | 50–60 | 0.75–0.80 | 1.20–1.28 | (0.4–1.25 mm) ≥95% | (≥90) | Grey | Good catalytic activity and mechanical strength; mainly used for ester synthesis or hydrolysis and for the alkylation of phenol. Dry resin is also available (water retention 3–5%) |
