ethermethyliquemonochlore - Preparation Method
Open Data Verified Data
The mixture of methanol and formaldehyde was reacted with hydrogen chloride gas. The raw materials and tail gas in the production process contain hydrogen chloride, which causes serious corrosion to the equipment. At present, domestic production uses water to absorb hydrogen chloride in the tail gas to increase by-products and reduce pollution.

ethermethyliquemonochlore - Safety
Open Data Verified Data
- highly toxic substances are carcinogens. In particular, the by-product dichloromethyl ether is more toxic and has strong irritation. The maximum allowable concentration in air is 1 × 10 -6. To strengthen equipment maintenance and repair, to prevent running, run, drop, leakage. Good ventilation should be maintained at the production site. When chloromethyl ether comes into contact with the human body, it is advisable to rinse with water. The operator should wear protective gear.
- It is packed in a polyethylene barrel, and good sealing is required. Store in a dry, cool, ventilated place, sunscreen, moisture-proof. According to the provisions of the storage and transportation of toxic chemicals.
