Phase behavior Triple point: 291.67 K (18.52 °C), ? Pa Critical point [2]: 720 K (447 °C), 5630 kPa Std enthalpy change of fusion, Δ fus H o: 14.37 kJ/mol Std entropy change
The first step of the Swern oxidation is the low-temperature reaction of DMSO, 1a, formally as resonance contributor 1b, with oxalyl chloride, 2.
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
Slow addition of preformed hydrazones to potassium tert-butoxide in DMSO as reaction medium instead of glycols allows hydrocarbon formation to be conducted successfully at temperatures as low as 23 °C. [16] Cram attributed the higher reactivity in DMSO as solvent to higher base strength of potassium tert-butoxide in this medium. Scheme 7.
Vacuum distillation can also be referred to as "low-temperature distillation". [ citation needed ] In distilling the crude oil, it is important not to subject the crude oil to temperatures above 370 to 380 °C because high molecular weight components in the crude oil will undergo thermal cracking and form petroleum coke at temperatures above that.
It's a classic tale: You have last-minute guests coming over for dinner or a bake sale fundraiser you didn't find out about until the night before—and now you need to concoct some tasty treats ...
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
