IMDG rules page: physicochemical properties

Appearance and properties: colorless liquid, with apple odor.

Main uses: used in rubber accelerators, organic synthesis and artificial flavors. Isovaleraldehyde is manufacturing isovaleric acid raw materials, intermediates for the synthesis of spices, food industry and pharmaceutical industry raw materials. Especially for the synthesis of vitamin E raw materials, the amount of great. Isovaleraldehyde occurs naturally in citrus and lemon. When highly diluted with apple aroma, the concentration of less than 10ppm when the peach flavor. China's GB2760-86 regulations to allow the use of edible spices, mainly used for the preparation of a variety of fruit flavors. The product is a medicine intermediate antispasmodic octamylamine the.

Stability: stability

Aggregation hazard: can occur

Contraindications: oxidant, alkali, strong reducing agent, air.

Fire fighting methods: sand, foam, dry powder, carbon dioxide.

Packing and storage: the 3.2 kinds of risk categories in the flash point of flammable liquids

Dangerous goods packaging logo: 7

Packaging category: II

Storage and transportation matters needing attention: usually the product adds the inhibitor. Store in a cool, ventilated room. Away from the fire, heat source. Warehouse temperature should not exceed 30. Keep out of direct sunlight. Packaging requirements are sealed and can not be contacted with air. Should be stored separately with the oxidant. Storage room lighting, ventilation and other facilities should be explosion-proof type. Fire and explosion proof technical measures should be used in the tank, and it is prohibited to use the equipment and tools that are easy to produce sparks. When moving to light light unloading, prevent damage to packaging and containers.

Leak disposal: cut off the fire source. Wear self-contained breathing apparatus, wear general fire protective clothing. In ensuring the safety of plugging. Spray mist can reduce evaporation. Rinse with plenty of water and put in a waste water system. Such as a large number of leaks, the dike shelter, then collect, transfer, or harmless treatment of waste recycling.

The cleaning of isovaleraldehyde:

Isovaleraldehyde has a strong pungent odor, cleaning the container has been a problem. It is said that the Qingdao Department of Yicheng chemical company developed a special cleaning agent for 3-methyl-butanal, isobutyraldehyde. Specific technical issues unknown.
