Web7 Feb 2024 · THF has been employed as a solvent and intermediate in industry for decades. THF has low boiling point (66°C) with a high vapor pressure (21.6 kPa at 25°C), which enables it easy recovery. In general, it is known that THF is highly polar and miscible with water, forming an azeotrope with water ( Howard, 1990; Kroschwitz et al., 2004 ). WebTetrahydrofuran (THF) is a clear, colourless, organic compound with an ether-like odour and the formula (CH2)4O. It is primarily used as a precursor to polymers including for surface coating, adhesives, and printing inks. It is water-miscible and has a low viscosity making it a highly versatile solvent used in a variety of industries. marlene hannan on facebook https://lamontjaxon.com
