Product Appearance:
Colorless liquid
Main Index:
Electronic grade: DEC ≥ 99.99%, methanol ≤ 20PPM, water ≤ 30PPM
Main Use:
Mainly used as nitrocellulose, resin and some drugs (such as erythromycin) solvent, and organic synthesis (such as phenobarbital, pyrethrin) intermediates. It can also be used as a solvent in the electrolyte of a lithium battery.
Operation, Disposal, Storage and Transportation:
Closed operation, full ventilation. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that the operator wear self-priming filter gas mask (half mask), safety protective glasses, anti-static clothing and rubber oil-resistant gloves. Keep away from fire and heat source. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapor leakage into the workplace air. Avoid contact with oxidizing agents, reducing agents and acids. When filling, the flow rate should be controlled, and there is a grounding device to prevent static accumulation. Handle lightly to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may leave harmful substances.
Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat source. The warehouse temperature shall not exceed 37 ℃. Keep container sealed. It should be stored separately from oxidizing agents, reducing agents, acids and edible chemicals, and avoid mixed storage. Explosion-proof lighting and ventilation facilities shall be adopted. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
