The Determination Of Ethanol In Aqueous Solution By Gas-Liquid Partition Chromatography, Robert L. Morrison
The Determination Of Ethanol In Aqueous Solution By Gas-Liquid Partition Chromatography, Robert L. Morrison
University of the Pacific Theses and Dissertations
The present chemical and physical methods for the determination of ethyl alcohol are all subject to systematic errors derived from any of a number of interfacing substances usually present in solution with the ethanol. Some of the most popular methods are slow and tedious and require a good deal of skill and technique to perform. The dichromate (2), pycnometer and refractometer methods are three such methods. The interfering substances most often present in industrial and food products are fusel oils and acetaldehyde. These substances interfere in the three methods just mentioned. It is of course possible to analyze for these …

Construction And Calibration Of Equipment For Obtaining Heat Capacity Data At High Temperatures, David Wells Wood
University of the Pacific Theses and Dissertations
This is a study of the heat capacity substances at high temperatures at determined by means of drop-calorimetry. The heat capacity may be defined as the quantity of heat required to raise the temperature of a substance by 1o C. This can be expressed as [see PDF file for formula]. The concept of heat capacity is used in connection with a certain defined path such as those of constant volume or constant pressure. The following definitions apply: [see PDF file for formula] = heat capacity at constant volume and [see PDF file for formula] = heat capacity at constant …
