<unk> 's volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes. In the food industry, it is used to decaffeinate coffee and tea as well as to prepare extracts of hops and other flavourings. Its volatility has led to its use as an aerosol spray propellant and as a blowing agent for polyurethane foams. Hydrogen bonding Methylene chloride is a Lewis acid that can hydrogen bond to electron donors. It is classified as a hard acid and is included in the ECW model. It is a solvent that has been used in many thermodynamic studies of donor-acceptor bonding. The donor hydrogen-bonding corrections of methylene chloride in these thermodynamic studies has been reported. Specialized uses Near IR absorption spectrum of<unk>  showing complicated overlapping overtones of mid IR absorption features. The chemical compound's low boiling point allows the chemical to function in a heat engine that can extract mechanical energy from small temperature differences. An example of a<unk>  heat engine is the drinking bird. The toy works at room temperature. It is also used as the fluid in Christmas bubble lights that have a colored bubbling tube above a lamp as a source of heat and a small amount of rock salt to provide thermal mass and a nucleation site for the phase changing solvent.<unk>  chemically welds certain plastics. For example, it is used to seal the casing of electric meters. Often sold as a main component of plastic welding adhesives, it is also used extensively by model building hobbyists for joining plastic components together. It is commonly referred to as "Di-clo." It is used in the garment printing industry for removal of heat-sealed garment transfers, and its volatility is exploited in novelty items: bubble lights and jukebox displays.<unk>  is used in the material testing field of civil engineering; specifically it is used during the testing of bituminous materials as a solvent to separate the binder from the aggregate of an asphalt or macadam to allow the testing of the materials.<unk>  extract of Asparagopsis taxiformis, a seaweed fodder for cattle, has been found to reduce their methane emissions by 79%. It has been used as the principal component of paint stripper, although replacements exist.
