Complete Guide to the Export Process of Glacial Acetic Acid as Class 8+3 Hazardous Goods via Shanghai Port
Overview of Basic Properties and Hazards of Glacial Acetic Acid
Glacial acetic acid is a colorless, transparent liquid with a strong pungent odor, chemically represented by CH₃COOH. It solidifies into ice-like crystals at low temperatures (below 16.7°C), hence its name 'glacial acetic acid' or 'ice vinegar.' This substance has extensive applications in the chemical industry but also poses significant transportation risks.
From a physicochemical perspective, glacial acetic acid has a flash point of 39°C and falls under the category of flammable liquids. Its explosion limit range is wide (4.0%-16.0%), meaning that when its concentration reaches this range in air, it can easily explode upon contact with an open flame. Additionally, glacial acetic acid is highly corrosive; it can corrode most metals (especially aluminum and zinc) and strongly irritates human skin, eyes, and respiratory mucosa. Prolonged exposure may lead to dermatitis, conjunctivitis, or even respiratory damage.
In hazardous materials classification systems, glacial acetic acid is categorized as class 8+3 hazardous goods due to its dual hazard characteristics: corrosiveness (class 8) and flammability (class 3). Its UN number is UN 2789 with CAS number 64-19-7. This dual hazard necessitates special caution during transport and storage while considering both corrosion prevention and fire/explosion safety measures.
Industrial Applications and Market Value of Glacial Acetic Acid
As an important organic chemical raw material, glacial acetic acid plays an irreplaceable role across various industrial sectors. In synthetic chemistry fields, it serves as a key raw material for producing vinyl acetate monomer (VAM), which forms the basis for manufacturing polyvinyl alcohol (PVA) and polyvinyl acetate (PVAc). In fiber industries, glacial acetic acid is used in producing cellulose acetate—a crucial ingredient for artificial silk films and certain plastics.
The pharmaceutical industry demands high-purity glacial acetic acid extensively; it's widely utilized as a solvent, acidity regulator, or raw material in synthesizing many antibiotics vitamins hormones etc., requiring its use throughout these processes. In food industries diluted versions are commonly employed as acidity regulators or preservatives; however strict purity standards must be met when using pure form.
Moreover production includes various acetate esters such as ethyl acetate butyl acetate—important industrial solvents—and metal acetates like lead(II)acetate zinc(II)acetate find broad application within dye catalysts preservatives manufacturing sectors respectively With increasing environmental regulations demand continues rising gradually replacing more toxic acids expanding market needs further still .
