APPLICATION:

Industrial applications

1. Mainly used to produce acetic anhydride, acetate, cellulose acetate, etc. Polyvinyl acetate can be made into films and adhesives, and is also the raw material for synthetic fiber vinylon. Cellulose acetate is used to make rayon and motion picture film.

2. Acetic acid is also a commonly used organic solvent, for example, it is used in the oxidation of paraxylene to produce terephthalic acid.

3. Acetic acid can be used in some pickling and polishing solutions, as a buffer in weakly acidic solutions (such as zinc plating, chemical nickel plating), as an additive in semi-bright nickel plating electrolyte, and in the passivation of zinc and cadmium. The solution can improve the binding force of the passivation film and is often used to adjust the pH of weakly acidic plating solutions.

4. Used to produce acetate, such as salts of manganese, sodium, lead, aluminum, zinc, cobalt and other metals, which are widely used as catalysts and additives in fabric dyeing and leather tanning industries; lead acetate is lead white in paint color; Lead tetraacetate is an organic synthesis reagent (for example, lead tetraacetate can be used as a strong oxidant, provide a source of acetoxy groups, and prepare organic lead compounds, etc.).

5. Acetic acid can also be used as analytical reagents, organic synthesis, synthesis of pigments and pharmaceuticals.

Food use

In the food industry, acetic acid is used as an acidifier, flavoring agent and spice to make synthetic vinegar. The acetic acid is diluted to 4-5% with water and various flavoring agents are added. The flavor is similar to that of alcohol-made vinegar. The production time is short and the price is low. Cheap.

As a sour agent, it can be used in compound seasonings to prepare vinegar, canned food, jelly and cheese. It can be used in appropriate amounts according to production needs.

It can also be used as a flavor enhancer for Quxiang wine, with a dosage of 0.1 to 0.3 g/kg.

  

PRICE TREND

On May 18-19, prices ran smoothly.

1. Pay attention to the current overall supply situation of the factory. The market price of glacial acetic acid went down last week, and the factory inventory mostly remained at a mid-to-low level. However, the downstream purchases are average and the prices have loosened. At present, the new long-term contract has begun, and the upstream and downstream purchase mentality will greatly affect the market price.

2. Upstream raw material situation

The cost of acetic acid has increased and profits have decreased.

3. International situation of glacial acetic acid

Asian CIF prices have been slightly lowered last week. Market prices in northwest Europe are stable,
