Chemical compound Difluoromethane, also called difluoromethylene, HFC-32 Methylene Fluoride or R-32, is an 2F 2. It is a colorless gas in the ambient atmosphere and is slightly soluble in the water, with a high thermal stability. [ failed verification] Due to the low melting and boiling point, (-136.0°C and -51.6°C respectively) contact with this compound may result in frostbite. [ failed verification] In the United States, the Synthesis [ ] Difluoromethane is primarily synthesized via batch processes, by the reaction of dichloromethane and hydrogen fluoride (HF), in the liquid phase using SbCl 5 as a catalyst. Applications [ ] Difluoromethane is often used as a fire extinguishant due to its ability to undergo endothermic processes. Difluoromethane is a molecule used as The common refrigerant Difluoromethane is currently used by itself in residential and commercial air-conditioners in Japan, China, and India as a substitute for Other uses of difluoromethane include its use as aerosol propellants, blowing agents, and solvents. Environmental Effects [ ] Every year, approximately 15 kilotons of difluoromethane are produced. HFC-32 released into the environment gets broken down into CF as an intermediate product. This goes on to create HF and CO 2 by hydrolysis in atmospheric water. The Difluoromethane is excluded from the list of Toxicity [ ] Difluoromethane shows slight maternal and developmental toxicity at concentrations of approximately 50,000 ppm in rats, but not in rabb...

Chemical compound 2-Methyltetrahydrofuran (2-MeTHF) is an 5H 10O. It is a highly flammable, mobile liquid. It is mainly used as a replacement for Structures and properties [ ] 2-Methyltetrahydrofuran is "inversely soluble" in water. That is, its solubility decreases with increasing temperature, which is a rare property. Preparation [ ] 2-Methyltetrahydrofuran is usually synthesized by OC 4H 3CHO + 4 H 2 → OC 4H 7CH 3 + H 2O Furfural is produced by the acid-catalyzed digestion of 5 2-Methyltetrahydrofuran can also be produced starting from Applications [ ] 2-Methyltetrahydrofuran is mainly used as a higher boiling substitute for tetrahydrofuran as a specialty Other common uses of 2-methyltetrahydrofuran is as a solvent for 2-Methyltetrahydrofuran is approved by the 2-Methyltetrahydrofuran has been promoted as an ecologically-friendly alternative to THF.
