Application
- 1. Used as an important raw material for the synthesis of doxycycline, dipyridamole, amoxicillin, cefadroxil intermediate, etc.
- 2. Widely used as a catalyst for reaction in organic chemical synthesis (such as ester products, textile auxiliaries, photographic film, electronic products, new materials, etc.).
- 3. Widely used as a curing agent in resins, paints, wood-based panels, foundry, paints, etc.. The curing speed is fast, and the paint film does not change color.
- 4. Widely used in chemical synthesis such as medicines and pesticides.
- 5. Catalytic use in electronics, polymer new materials, flavors and fragrances and daily chemical products.
Package
25kg plastic woven bag / 25kg drum or as requirements
