1,2-Dichloropropane (CAS 78-87-5) is a colorless, highly flammable organic solvent with a sweet, chloroform-like odor. Primarily used in industrial applications such as adhesives, coatings, and chemical synthesis, it is valued for its strong solvency. Due to its toxicity and potential health risks, its use is strictly regulated in many countries, requiring careful handling and compliance with safety standards.
1,2-Dichloropropane, also known as propylene dichloride, is a chlorinated hydrocarbon used as a solvent in specialized industrial processes. With a boiling point of approximately 96°C and a density of 1.236 g/cm³ at 20°C, it is effective for dissolving oils, greases, and resins. However, its high flammability (flash point ~16°C) and toxicity necessitate strict safety protocols to prevent inhalation or skin exposure.
Strong Solvency: Effectively dissolves a wide range of organic materials.
Industrial Versatility: Suitable for adhesives, coatings, and chemical intermediates.
Regulated Use: Subject to strict environmental and safety regulations due to toxicity.
Flammable: Requires careful handling to prevent fire hazards.
