The Determination of the Water Content in Acetaldehyde by Means of the Karl Fischer Reagent
Autor: Kunihiko Ogawa, Yaeko Ishii, Kaname Muroi
Publikováno v: Bulletin of the Chemical Society of Japan. 38:1176-1181
Approximately 5 ml. of the sample has been added to 5 ml. of a 3:1 solvent mixture of of pyridine-propylene glycol in a titration flask. The difference in boiling point between acetaldehyde and water made it possible to evaporate almost all the inter

The Determination of the Water Content of the Low Polymers of Formaldehyde by the Karl Fischer Method. I. The Determination of the Adsorbed Water and Bound Water Formed by the Pyrolysis of the Polymer
Autor: Kaname Muroi, Kunihiko Ogawa
Publikováno v: Bulletin of the Chemical Society of Japan. 36:965-969
The adsorbed water of the low polymer of formaldehyde was determined by extraction with dry methanol and Karl Fischer titration. The sum of the adsorbed water and the water formed by the pyrolysis of the sample was determined by titration with the sp

The Determination of Trace Water in the Grease by the Karl Fischer Method
Autor: Yaeko Ishii, Kunihiko Ogawa, Kaname Muroi
Publikováno v: Journal of The Japan Petroleum Institute. 9:194-197
The indirect titration using the Karl Fischer reagent was applied in the determination of trace water in grease. 20∼30ml of insulating oil was placed in the round bottomed flask with gas inlet tube and gas outlet tube, and heated to 120∼140°C, a
