1. Product Introduction & Main Application
Arnico’s Acetaldehyde is a clear, colorless, highly volatile, and flammable liquid with a pungent, fruity odor, recognized as a key chemical intermediate in organic synthesis. This substance, obtained from the oxidation of ethylene (the Wacker process), is the primary raw material for the production of acetic acid, pyridine, pentaerythritol, and aldehyde-based resins, with vital applications in the flavor and fragrance industries.

5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This liquid is extremely flammable (Flash Point ≈ -39°C), volatile, and toxic. Inhalation is a severe lung irritant and it is a suspected carcinogen. The Arnico MSDS is mandatory.
-
Storage Conditions: Store in nitrogen-pressurized tanks in a refrigerated environment (below 10°C), away from sparks, heat, and alkaline and oxidizing materials. Equipment must be completely explosion-proof.
-
Personal Protective Equipment (PPE): The use of a full-face respirator with an AX and formaldehyde-specific filter, Viton gloves, and anti-static clothing is mandatory.
