Product Name:

Industrial Acrylonitrile

Trade Mark:

Sanren Brand

Alternative Name:

Cyano-ethylene

Molecular Formula:

Production Process:

Using propylene, ammonia and air as raw material, the product is made by once-through direct oxydation.

Properties:

The product is a colourless inflammable liquid with drastic toxicity and irritation smell. It dissolves slightly in water and quite well in common organic solvent. There exists the danger of burning and explosion when it meets with fire, high temperature and oxidant. Acrylonitrile vapor and air can form an explosive mixture with the explosion limits between 3.1%-17% (vol.). The boiling point is 77.3℃, the flash point -5℃ and the autoignition point 481℃.

Major Applications:

The product is the raw material for synthetic fibre, synthetic rubber, synthetic resin, dyestuff and medicine.

Packing:

Bulk (tank truck) or in drum with a net weight of 150 kg.

Storage:

The product should be stored in special storage tank. The drummed acrylonitrile should be kept in a special warehouse with roof for toxic and inflammable liquid (In compliance with the Safety and fireprevention rules).

Transportation:

The special tank truck can be used for transportation. For drummed product, truck or rail-way transportation is applicable.

Safety Precautions:

1. During transportation and storage, neither pressure nor heat should be applied to the product. The relevant government rules and regulations concerning transportation and storage of hazardous chemicals must be strictly followed. The special tank truck should be equipped with static electricity grounding device and extinguishers.
2. The product should be kept in a ventilated place where the temperature is below 30℃ and isolated from fire. It can not be exposed to sunlight for a long period of time and transported and stored with oxidant, acid alkali and amine to prevent from volatilizating, burning or poisoning.
3. Labour protection measures for protection of skin and respiratory organs should be taken for those who contract the product. The analysis of the product should be conducted in a draught cupboard. The max. acrylonitrile concentration in the atmosphere around the working area should not exceed 2 mg/m3.
4. The extinguishers for the product are as follows: foam, carbon dioxide, 1211, dry powder, sand etc. In case of overflow, treat it with 10% NaOH and 20% ferrous sulfate solution. All the treatment and cleaning work should be done under the condition of ventilation and the people doing the job should wear gas masks.
