Web20 Apr 2001 · THF is a stronger solvent in RP-HPLC and phenolic monomers can be eluted much faster. The five monomers can be baseline separated when THF content is less … Web7 Feb 2024 · 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 ).
