The Influence Of Agitation On A Continuous Counter-Current Liquid-Liquid Extraction Column, William John Hartmann

Theses

This work presents operating data and correlations of agitated extraction equipment studied under continuous counter-current flow.

The experimental work was carried out in at agitated column 36 inches in length with an internal diameter of 2 inches using the system toluene, benzoic acid and water. The working section of the column was 24 inches. The design of the column used for the experimental work is similar to that proposed in a patent by van Dijck (3). The column is similar only to the extent that the patent covers numerous conditions of vertical agitation.

The distribution data and the equilibrium solubility …

Nitration Of Derivatives Of 2,5-Dichlorobenzenesulfonic Acid, William J. Conradi

Theses

The proof that a nitro group enters meta to the sulfonic acid group of 2,5-dichlorobenzenosulfonamide and 2,5-dichlorobenzenosulfonanilide is presented.

The preparation of several new compounds is described.

An unsuccessful attempt to prepare 2,5-dichloro-3-nitrobenzenesulfonyl chloride from 2,5-dichloronitrobenzene is also described.

The Effect Of Surface Tension Upon The Flow Of Fluids Through Packed Beds, William Charles Streib

Theses

Flow tests through beds of unconsolidated sand, glass beads and 1/4 inch Berl saddles showed that wide variations in the surface tension of a fluid had no significant effect on its flowrate through the bed. Viscosity and density were the only fluid properties affecting such flow. Excellent comparative results were observed between the flowrates through sand beds and those predicted by the Leva equation.

The complex Brownell and Katz equation for predicting the residual saturation of a packed bed was found to apply for fluids having a much wider range of surface tension than those originally used to derive their …

Preparation And Spectra Of M-Nitrobenzoates And M-Aminobenzoates, Peter Tikey Kapsamalis

Theses

A study of the synthesis of a series of new m-nitrobenzoates, m-aminobenzoates and several derivatives of the latter is presented.

Physisal constants and analytical determinations are presented, including the ultraviolet absorption spectra of the compounds prepared.

Ultrafiltration In The Pigment Field : A Critical Literature Survey, Charles Walter Manger

Theses

The objective in this work has been to determine, through a critical literature survey, the possible application of ultrafiltration, and other related techniques, towards the solution of certain problems encountered in the research and testing of various pigments.

Among these problems may be mentioned the following:

1. The determination of water-soluble salts in pigments, which when dispersed in water to leach out the salts, tend to peptize, thus being unfilterable through the usual filter paper. Among these pigments are the following: iron blue, certain chrome yellows, pigment green B, copper maroon, and several others. It may be added that these pigments …

Correlation Of The Number Of Theoretical Plates Vs. Reflux Ratio, George Ignatius Parisi

Theses

A correlation is presented from which the number of theoretical plates for a given separation by distillation can be estimated as a function of the reflux ratio. The effects of relative volatility and feed composition upon such a correlation are also studied. Smoker's (1) equation was used in calculating the data. The results were obtained by varying the several parameters which have to be given for any separa tion desired. These include feed compositions of 0.25, 0.50, and 0.75; relative volatilities of 1.1, 1.2, 1.5, and 2.0; and various reflux ratios. The overhead product and bottoms product compositions were kept …

Substituted Ureas, Roy Earl Parks

Theses

Nitrosomethylurea in aqueous medium decomposes on heating to methanol, nitrogen and cyanic or isocyanic acid. Primary amines present during the decomposition react with cyanic acid to form substituted ureas, readily isolated in high purity and good yield.

Isobaric Heat Capacity Of Ethylene Over A Wide Range Of Temperature And Pressure, Robert John Sibilia

Theses

The effect of pressure and temperature on the isobaric heat capacity at constant volume for ethylene relative to the ideal gas state is presented. The results cover pressures from 0 to 10,000 FA and temperatures from 32.0°F to 2372.0°F.

The deviation of the isobaric heat capacity of ethylene from the ideal gas state for the wide range of pressure and temperature covered was found from an equation derived from the Benedict-Webb-Rubin equation of state. Graphs and tables relating the deviation of the isobaric h capacity: the deviation of heat capacity at constant volume, pressures and temperature are included.

The results …

An Investigation Of The Use Of Surface-Active Agents In The Secondary Recovery Of Oil By Water Flooding, Robert P. Schafer

Masters Theses

"The importance of producing oil cannot be emphasized enough in this modem world. Therefore, when primary methods of production seemingly exhaust the oil reservoirs, a secondary method of producing more oil is a necessity. At the present time, secondary methods of oil recovery have developed into a large industry. They are not a new development. The need of introducing compressed air or air-gas mixtures into the wells to increase production was quickly realized. Water flooding methods followed, and at first were restricted to the Eastern fields. Later, about 1935, systematic water flooding methods were developed and applied all over the …
