The Synthesis And Cyclization Of 5-Chloro-2, 3-Dichloroacetamidopyridine, Edward Aloysius Naiman Jun 1960

The Synthesis And Cyclization Of 5-Chloro-2, 3-Dichloroacetamidopyridine, Edward Aloysius Naiman

Theses

The acetylation of 5-chloropyridine-2,3-diamino with chloroacetyl-chloride to yield 5-chloropyridine-2,3-dichlo-roacetamide and the subsequent ring closure form 6-chloro-2-chloromethyl-3H-imidazo-(b)pyridine has been studied in detail. The method of experimentation utilized statistically designed mathematical experiments.

The yield of 5-chloropyridine-2,3-dichloroacetamido is dependent upon the excess of the reactants and temperature, while time is not a significant factor. An important contribution to the study was obtained by extracting the product with solvents and discovering that the ring closed material 6-chloro-2-chloromethyl-3H-imidazo-(b)pyridine yields in quantity during the diacetylation reaction.

The ring closure of 5-chloro-2,3-dichloroacetamidopyridine is markedly temperature dependent. Time has little effect on the reaction yield. The analysis of …


Fugacity Coefficients Of Gases In Binary Mixtures, David W. H. Roth Jun 1960

Fugacity Coefficients Of Gases In Binary Mixtures, David W. H. Roth

Theses

Fugacity coefficients of components in gaseous mixtures have been calculated by a method proposed by Joffe which is based on the use of generalized thermodynamic functions, and on Kay's rule for definition of the pseudocritical points of a gaseous mixture. The method should be applicable to compounds which can be correlated by the theory of corresponding states.

The method was tested by application to 255 experimental points comprised of four gaseous systems, and included Argon-Ethylene, Hydrogen - Nitrogen, Methane - Ethane, and Methane n Butane. Thermodynamic functions from two recent generalized correlations, that of Pitzer et al., and that of …


Heat Transfer Coefficients In Nucleate Boiling, Gerald Burt Fefferman Jun 1960

Heat Transfer Coefficients In Nucleate Boiling, Gerald Burt Fefferman

Theses

The purpose of this study was to investigate some new approaches to the problem of correlating heat transfer coefficients in nucleate boiling, A survey of previous work done in this field reveals much inconsistency in recorded data relating the heat transfer coefficient to other properties of the observed system, but general agreement has been reached, however, concerning the important influence of the temperature difference between the heating element surface and the boiling liquid. As this temperature difference is increased, the surface coefficient of heat transfer rises until a critical point is reached, marking the end of nucleate boiling and the …


Particle-Liquid Flow In Vertical Tubes, Frederick John Rowe Jun 1960

Particle-Liquid Flow In Vertical Tubes, Frederick John Rowe

Theses

It was the purpose of this investigation to develop an experimental Procedure which would allow the prediction of the variation of fraction void with varying liquid and solid rates from a minimum number of experiments carried out in simple apparatus. This procedure should allow prediction for both smooth and rough particles, and should be valid for several different shapes. The data collected can be plotted on a single chart showing the relation between fraction void, solids throughput, and liquid throughput for all vertical particle fluid systems. Such a method was suggested by Mertes and Rhodes1 in their work developing a …

Irrigation And Drainage Problems In Uruguay, Jerald Emmet Christiansen Jun 1960

Irrigation And Drainage Problems In Uruguay, Jerald Emmet Christiansen

Reports

Synopsis: Uruguay irrigates about 65,000 acres, mostly rice (74%) and sugar cane (15%). Summer rainfall averages about 3.5 in. per month, but frequent droughts seriously affect both crops and livestock. Irrigation can be increased by storage in small reservoirs on tributary streams by means of low earth dams. Some areas will require flood control and draiange before intensive agriculture can be practiced.


Criteria For Design Of Pavement Thicknesses, Kentucky Interstate Highways, William B. Drake, James H. Havens Jun 1960

Criteria For Design Of Pavement Thicknesses, Kentucky Interstate Highways, William B. Drake, James H. Havens

Kentucky Transportation Center Research Report

The Kentucky Department of Highways, in 1946, sought a more systematic criteria and basis for designing the thickness of bituminous concrete pavements. The Research Division was authorized to pursue this work and to develop the criterion. These efforts were embodied in a report (1) to the Department, which offered a system of design based upon CBR's and EWL's. EWL's were computed originally for a 10-yr. period but this practice was revised in 1954, to encompass 20-yr. traffic (more realistic with respect to average road life). Then, in 1957, the Department requested a re-evaluation of the criteria from the standpoint of …


Absolute Viscosity Of The N-Paraffin Liquids, Gerald Permutt May 1960

Absolute Viscosity Of The N-Paraffin Liquids, Gerald Permutt

Theses

The absolute viscosity of the normal paraffins C5H12 to C20H42 was studied to determine a relationship more useful in predicting liquid viscosities than existing correlations such as the methods of Andrade, Souders, Thomas, and Doolittle.

It was found that a function of corresponding liquid states could be designed which related viscosity to the number of carbon atoms. This function, here called liquidity, is defined as the extent to which a substance exists as a liquid with respect to temperature. This function can be expressed mathematically as:

Lc = (t - tm)/(t …

A Useful Farm-Made Roller, V E. Western Jan 1960

A Useful Farm-Made Roller, V E. Western

Journal of the Department of Agriculture, Western Australia, Series 4

A very serviceable compacting roller can be constructed at little expense by using discarded truck tyres.

The roller described here has an overall width of 5 ft. 3 in. and carries seven 9.00 x 24 semi-trailer tyres which had been discarded when the treads were worn smooth.


Overcoming Stock Watering Problems In The Kimberleys, B Swan Jan 1960

Overcoming Stock Watering Problems In The Kimberleys, B Swan

Journal of the Department of Agriculture, Western Australia, Series 4

ONE of the ever-present problems of the pastoral areas is that of providing: watering-points in reasonably close proximity to the grazing areas.

All too frequently, the country on the river frontages and that in the vicinity of the water-holes becomes eaten out and although there may be ample feed on other portions of the run, it is too far distant from the available water to be effectively utilised.

Comprehensive Survey Of Sedimentation In Lake Mead, 1948-49, W. O. Smith, C. P. Vetter, G. B. Cummings, U.S. Bureau Of Reclamation

Publications (WR)

Reservoirs are becoming an increasingly prominent feature of the American landscape. Built for flood mitigation and to change a fluctuating river into a dependable source of water for irrigation, power, and other purposes, they are predestined, like natural lakes, to be destroyed sometime following their creation. Sedimentation sooner or later robs most lakes and reservoirs of their capacity to store water. The significance of sedimentation in the life of Lake Mead, the largest artificial reservoir in the world, was realized when the plan for the reservoir was conceived, and an aerial survey of the floor was made in 1935 before …
