Naxcat® 330L

1 of 12 products in this brand

Naxcat® 330L is a high-purity TSA (toluenesulfonic acid) that is 65% active in water with low free sulfuric acid. It is designed to replace p-TSA monohydrate in many industrial catalysis applications. The product is manufactured using a proprietary purification technique that is not practiced elsewhere in the industry. Naxcat® 330L meets quality standards previously achieved only by using crystalline p-TSA, including low concentrations of sulfuric acid, iron, sulfones, and hydrocarbons. It offers ease of use with the relatively low cost of liquid mixed isomer TSA solutions. For reduced process time, labor savings, ease of use, and saved clean-up time, Naxcat® 330L allows for directly pumping catalyst into your reactor without the need to predissolve or preblend the compound, provided your catalysis needs allow it.

Storage & Handling

Storage Information: Keep container tightly closed when not in use. Store in cool, well ventilated area. Steel is corroded by sulfonic acids and is not recommended for prolonged storage at elevated temperatures since iron and color contamination could result. Dilution with water may increase corrosivity of the acid. Material will absorb moisture.
