Viscose cellophane as a base for a smoking product
(Virginia Agricultural and Mechanical College and Polytechnic Institute, 1940-09-01)Recognizing that natural tobacco has many undesirable features, such as drying, crumbling, and the nicotine content, this study investigated the properties of a good smoking tobacco and attempted to discover a cellulose ... -
The preparation of an interior varnish from tobacco seed oil
(Virginia Agricultural and Mechanical College and Polytechnic Institute, 1942)Tobacco seed oil was expressed from the seed and purified by centrifuging. Four interior varnishes were prepared. Three of these varnishes contained tobacco seed oil as one of the drying oils. A satisfactory interior varnish ... -
The grinding characteristics of laboratory rod mill

A corrosion measurement testing unit for use with tallol
(Virginia Tech, 1944-05-05)Although no corrosion measurements have been made, preliminary operation indicates that it is possible to make them under conditions of constant rate of flow of corroding material, composition of corroding material, and ... -
The production of nylon from phenol
(Virginia Polytechnic Institute, 1946) -
A study of the effect of changes of procedure in a standard sulfate determination
(Virginia Polytechnic Institute, 1952-06-05)The work done by the author indicates that when %s is determined by gravimetric methods as indicated the volume and concentration of reagents used is very important. It appears that an excess of KBr solution will cause ... -
A synthesis of 3-acetyl-6-methoxybenzaldehyde utilizing the Fries reaction
(Virginia Polytechnic Institute, 1953)Introduction: In the yea.rs since World War II there has been an increasing number of attempts to produce various types of effective herbicides, and as a result of the extensive time and labor required for random testing ... -
Determination of the mean particle diameter, particle density, and fraction voids of Ottawa sand
(Virginia Polytechnic Institute, 1955)Fluidization is one of the most recent developments in the field of unit operations. It occurs when particles of solids are maintained in a dense turbulent state by means of a moving fluid. The literature pertaining to ... -

Equilibrium data for the system air-acetone-activated carbon at temperatures of 20,27 and 34 degrees C at atmospheric pressure
(Virginia Polytechnic Institute, 1958)The use of activated carbon for removing color from organic solutions has been known since the seventeenth century. Industrial use of activated carbon as an adsorbent was not possible until 1900 because of inadequate ... -
The synthesis of a polythioester from adipic acid and 1,2- ethanedithiol
(Virginia Polytechnic Institute, 1958)The purpose of this investigation was to synthesize a polythioester from adipic acid and 1,2-ethanedithiol. Due to the commercial unavailability of 1,2-ethanedithiol it was decided to synthesize 1 t from sodium hydrosulfide ... -
Frequency response of a feed preheater
(Virginia Polytechnic Institute, 1962)The purpose of this investigation was to measure the frequency response of a shell and tube heat exchanger when the input is the pressure to the steam valve and the output is the feed temperature. During this investigation ... -
