Delving into the technical specifications of a chemical compound like R141b provides valuable insight into its industrial utility and historical significance. R141b, chemically known as 1,1-Dichloro-1-fluoroethane, possesses a unique set of properties that led to its widespread adoption in various sectors.

Physically, R141b is a colorless, volatile liquid with an ethereal odor. Its boiling point of approximately 32°C makes it suitable for applications where controlled evaporation is required. The chemical formula C2H3Cl2F indicates a molecule containing carbon, hydrogen, chlorine, and fluorine. These elements contribute to its solvent capabilities, allowing it to effectively dissolve greases, oils, and other organic residues, making it an excellent choice for cleaning purposes. The R141b refrigerant chemical properties were key to its success as an industrial cleaner.

In its role as a foam blowing agent, R141b facilitated the creation of lightweight, insulating polyurethane foams. The controlled expansion of the gas during the foaming process resulted in closed-cell structures that provided excellent thermal insulation. This property made it a popular choice for insulating refrigerators, freezers, and building materials. The extensive R141b refrigerant applications in foam production highlight its impact on energy efficiency in various products.

The CAS number for R141b is 1717-00-6, a unique identifier for this chemical compound. Its molecular weight is approximately 116.95 g/mol. While R141b offered advantages over CFCs, its ozone depletion potential (ODP) of around 0.11 and a global warming potential (GWP) of 700-725 mean that its use is now restricted under international environmental regulations. Understanding these technical details is crucial for appreciating why the industry is transitioning to new generations of chemicals.
