Properties and stability
Keep away from oxidants, reducing agents, acids, bases, protic solvents, light, heat, open flames, high temperatures, moisture, moisture, and static charges.
It is highly toxic and has irritating effects on all tissues. It is flammable and may cause combustion and explosion when exposed to open flame, high heat or contact with oxidants. Emit highly toxic fumes when exposed to heat, acid or acid mist. Self-priming filter gas masks must be worn when there is a possibility of contact with its vapor. Wear an oxygen respirator during emergency rescue or evacuation.
Storage method
Store in a sealed container in a cool, dry place at room temperature away from light. Store away from oxidizing agents.
Synthesis method
Chloromethyl acetate is prepared by chloromethylation reaction using acetyl chloride and paraformaldehyde as raw materials under the action of anhydrous zinc chloride.
Purpose
Used as solvent and raw material for adhesives and surfactants.
