The purity of rectified spirit has a practical limit of 97.2% ABV (95.6% by mass) [2] when produced using conventional distillation processes, as a mixture of ethanol and water becomes a minimum-boiling azeotrope at this concentration. However, rectified spirit is typically distilled in continuous multi-column stills at 96–96.5% ABV and ...
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...

Tetraethylene glycol dimethyl ether (TEGDME or tetraglyme) is a polar aprotic solvent with excellent chemical and thermal stability.Its high boiling point and stability makes it an ideal candidate for separation processes and high temperature reactions.
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
Sigma-Aldrich has replaced Nonidet P-40 with IGEPAL CA-630, which is described as a "nonionic, non-denaturing detergent". Sigma-Aldrich claims that IGEPAL CA-630 is "chemically indistinguishable from Nonidet P-40". IGEPAL consists of octyl-phenoxy(polyoxyethylene)ethanol. Tergitol and the Sigma and BioChemica Nonidet P40 substitute detergents ...
