? How Does Methylene Chloride Work?

1. Powerful Solvent Action:

• Effectively dissolves paints, coatings, adhesives, and organic materials.

• Đảm bảoquick dryingVàminimal residue in cleaning applications.

• Được sử dụng trongchemical extractions for food, pharmaceuticals, and research.

? Phương pháp sản xuất & Nguyên liệu thô

✔ Chemical Synthesis Process:

1. Nguyên liệu thô: Methane & Chlorine gas

2. Sự phản ứng lại: Chlorination of methane (CH₄) to produce methyl chloride, which is further chlorinated to form dichloromethane (DCM).

3. Purification & Distillation: The crude DCM is distilled and purified to obtain high-purity methylene chloride.

? Safety & Handling Precautions

• Use in a well-ventilated area to prevent inhalation of vapors.

• Wear protective gloves, goggles, and clothing during handling.

• Store in tightly sealed containers away from heat, sparks, and open flames.

• Avoid prolonged exposure, as DCM can have health risks such as dizziness, irritation, and long-term toxicity.
