Naxcat® TSA-95

1 of 12 products in this brand
Naxcat® TSA-95 is the strongest of our organic acids and is the most suitable esterification catalyst for the production of phthalates and other plasticizers. Aromatic sulfonic acids are created by sulfonating aromatic compounds with sulfuric acid, SO3, or oleum. They are similar in strength to mineral acids like sulfuric acid, but they are particularly useful for organic reactions where an inorganic, mineral acid may cause charring, oxidation, or an unwanted chemical reaction.

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.
