1. Product Introduction & Main Application
Arnico’s Acetic Acid is a weak organic acid, clear and with a sharp, characteristic odor, supplied in both Glacial (99.9% purity) and Industrial grades. This substance, acting as a polar solvent, acetylating agent, and pH regulator, is one of the most vital chemical intermediates in the world, used in the production of Vinyl Acetate Monomer, cellulose acetate, and Purified Terephthalic Acid (PTA) for PET production.

3. Features & Benefits
-
Exceptional Glacial Purity: Free from metals and organic impurities, which is essential for producing bottle-grade PET that is clear and odorless.
-
Guaranteed Reactivity: High acetylating power for the production of cellulose acetates, vinyl acetate, and ester solvents with excellent conversion efficiency.
-
Dual Solubility: The ability to dissolve both in water and in many organic solvents, making it an unparalleled chemical intermediate.
-
Chemical Stability: Resistant to oxidation and discoloration over time and in high-temperature processes.
4. Industrial Applications
-
Petrochemical & Polymer Industries: The primary raw material in the production of Vinyl Acetate Monomer (VAM) and Purified Terephthalic Acid (PTA) for the polyester chain.
-
Food Industry: An acidulant and preservative (E260) in the production of sauces, pickles, and industrial vinegar.
-
Pharmaceutical Industry: A solvent and catalyst in the synthesis of antibiotics and paracetamol.
-
Textile Industry: A fixing agent for disperse dyes in the dyeing of polyester fibers.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): Glacial acetic acid is flammable and severely corrosive, and its vapors cause serious damage to the respiratory tract and eyes. The complete Arnico MSDS must be studied before use.
-
Storage Conditions: Store in 316 stainless steel or aluminum tanks, at a temperature above 18°C to prevent crystallization, and away from oxidizing agents, bases, and sources of ignition.
-
Personal Protective Equipment (PPE): When handling, the mandatory use of a full-face respirator with an organic/acid gas filter, Viton gloves, and acid-resistant clothing is required.
6. Quality Assurance & COA
Arnico Acetic Acid shipments are accompanied by a validated COA that includes precise Gas Chromatography (GC) results for purity and formic acid impurities.
