HALOTHANE CONCENTRATIONS OBTAINED WITH A DRAGER “VAPOR” VAPORIZER

open access: bronzeBritish Journal of Anaesthesia, 1963
The design and testing of a Vapor vaporizer for halothane by Dragerwerk is described. The tests substantiate the makers claims that the vaporizer is accurate, stable and unaffected by pressure fluctuations produced by the action of a ventilator.

Are Conventional Thermochemical Calculations a Viable Alternative to Measurements of Vaporization Enthalpy of Azeotropes? [PDF]

open access: yesMolecules
The majority of the studies of vaporization enthalpy dealt with pure substances. Reports of this quantity for azeotropes were scarce despite that similar experimental methods could be applied in such measurements.

Purification of Chlorophenol Isomers by Stripping Crystallization Combining Melt Crystallization and Vaporization

open access: yesMolecules, 2021
Stripping crystallization (SC) was introduced in this work to purify p-chlorophenol from the p-chlorophenol-rich liquid mixture and to purify m-chlorophenol from the m-chlorophenol-rich liquid mixture, respectively.

The Ionic Product of Water in the Eye of the Quantum Cluster Equilibrium

open access: yesMolecules, 2022
The theoretical description of water properties continues to be a challenge. Using quantum cluster equilibrium (QCE) theory, we combine state-of-the-art quantum chemistry and statistical thermodynamic methods with the almost historical Clausius–Clapeyron

A Model for Predicting Arsenic Volatilization during Coal Combustion Based on the Ash Fusion Temperature and Coal Characteristic

open access: yesEnergies, 2021
Arsenic emission from coal combustion power plants has attracted increasing attention due to its high toxicity. In this study, it was found that there was a close relationship between the ash fusion temperature (AFT) and arsenic distribution based on the
