PROCESS FOR DEHYDRATING A MINERAL OIL OR OTHER SOLVENTS FOR THE PREPARATION OF MOISTURE-IN-OIL OR MOISTURE-IN-SOLVENT STANDARDS

摘要

An oil, such as a mineral oil, for example, transformer oil, is contacted with calcium carbide and the mixture is stirred until a liquid phase containing less than 1 ppm water and a solid phase containing Ca(OH)2 and unreacted CaC2 are obtained. The oil obtained can be used to give samples of known quantities of water by adding corresponding amounts thereto.
