Web2-Methyltetrahydrofuran (2-MeTHF) is an organic compound with the molecular formula C 5 H 10 O. It is a highly flammable, mobile liquid. It is mainly used as a replacement for Tetrahydrofuran (THF) in specialized applications for its better performance, such as to obtain higher reaction temperatures, or easier separations (as, unlike THF, it is not … Webazeotropes, while pressure minimum azeotropes are called negative azeotropis. The coordinates of an azeotropic point are the azeotropic themperature t az, pressure p az, and liquid phase composition. This table gives azeotropic date for a number of binary muxtures at normal atmospheric pressure (p az =101,3kPas). Component 1 Component 2 Name ...

It covers from 0 to 1 in steps of 0.1 with an additional point 0.45 near the azeotropic point 0.46 (Burtle, 1952).These boxes were energy minimized and equilibrated at desired temperature to obtain the liquid density.
WebWhen the composition of a binary azeotrope is closer to 1:1 (as is the case for i-PrOH–i-PrOAc, for instance) solvent chasing from either solvent to the other will require less solvent. Some ternary azeotropes (solvent–solvent–water) that may be encountered are shown in Table 5.10 [36].
