Heat Capacities Of Ethane Over A Wide Range Of Temperature And Pressure, Thomas Agens Reiter

Theses

The effects of pressure and temperature on the isobaric heat capacity, the constant volume heat capacity, and the ratio of heat capacities of ethane are presented. The range of conditions covered are pressures from 0 to 10,000 psia and temperatures from 180 to 1400°F. The calculation of these effects is based on equations derived from the Benedict-Webb-Rubin equation of state. The derived equations express the deviations of the heat capacities from ideal gas behavior.

The results show that ignoring the effect of pressure en the heat capacities of ethane may lead to large errors in engineering calculations. Graphs and tables …

The Reduction Of Aromatic Nitro Compounds With Anhydrous Stannous Chloride, Raymond Albert Unnasch

Theses

With the publication of a method for the preparation of anhydrous stannous chloride (1), T. E. de Kiewiet and H. Stephen were prompted to investigate its use in the reduction of aromatic nitro compounds under anhydrous conditions. In a paper entitled "A New Method of Reducing Aromatic nitro Compounds" (2), reporting the results of this investigation, they claimed simultaneous reduction, acetylation, and also chlorination in the position para to that of the original nitro group.

Linear Growth Rates Of Single Copper Sulfate Crystals, Arthur Oswald Hansen

Theses

The purpose of this work was to study and measure the factors influencing crystal growth.

Approximately 250 single crystals of CuSO₄.5H₂O were grown under controlled conditions of supersaturation, solution velocity, and temperature.

The data from this work indicates that:

(a) Crystal growth rate is independent of crystal size for the size range covered (4 to 12 mesh).

(b) Crystal growth rate is directly proportional to the degree of supersaturation, or driving force for each concentration of solution studied.

(c) Crystal growth rate varies exponentially with the velocity of the solution passing the crystal

Heat Transfer Characteristics Of Non-Newtonian Suspensions, Harold Binder, Paul Pollara

Theses

The following equation was developed by Dr. J. J. Salamone for calculating the fibs coefficient of heat transfer to non-Newtonian suspensions in turbulent flow (Re 50,000 - 200.000) inside of pipes:

h_D/K_f = 0.131 (DV_bPb/u_b)^0.62 (D/D_s)^0.05 (C_s/C_f)^0.35 (C_fu_b/K_f)^0.72 (K_s/K_f)^0.05

This equation was investigated to determine its validity over the lower turbulent regions of the Reynolds number (10,000 - 70,000), and to test the exponents of the various components.

Equipment was constructed similar …

Heat Transfer Characteristics Of Non-Newtonian Suspensions, Robert Gregory Quinn, Irving Bauman

Theses

This project was undertaken to collect additional information on the heat transfer coefficients of pseudo-plastic suspensions and to test the exponents of the equation of Salamone (12). Using the same equation as derived by Salamone by dimensional analysis, a better correlation of this data was obtained by changing some of the exponents to give the following equation:

LD/K_f=0.346(D_vp/M^{`</sup>)<sup>0.7</sup>(C<sub>f</sub>M<sup>`}/K_f)^0.72(D_s/D)^0.15(C_s/C_f)^0.35(k_s/k_f)^0.08 (1)

The authors believe that a better correlation is possible and …

A Study Of A Synthesis Of Indole, Stephen Scala

Theses

Chemical literature abounds with methods for the synthesis of Indole and its derivatives. Undoubtedly, this is so, because Indole is the parent substance of the historical dyestuff Indigo. This coloring material has been the subject of extensive investigations for many centuries. Early in this century, importance was still placed on Indole Chemistry, but it later gore way to other dyestuffs having different chemical structures. It seems, however, the loss in popularity was to have been short-lived, because of the revitalized interest shown in the chemistry of Indoles since the early 1930's.

It was found that a great number of alkaloids …

Cost Reduction Through Closer Control Of Quality, Walter Robert Kuzmin

Theses

The economy of our nation differs today from that of World War II or pre-World War II days by the fact that a war-production program is being carried on without adversely affecting the production or civilian goods, At the same time management is confronted with rising costs due to the inflationary spiral of wanes and materials. To mire a profit on Products and remain in competition, management is forced to apply the latest cost reduction methods. Because of the dual economy, companies are quoting on civilian goods and war Products. Contracts released by the government specify that; adequate inspection and …

The Synthesis Of 2-Amino-4-Chlorophenol-6 Sulfonic Acid, Herman Albert Bronner

Theses

The work described in this thesis was undertaken with the view of exploring a reaction sequence suggested by early French investigators to synthesize 2-amino-4-chlorophenol-6-sulfonic acid especially in reference to the German claim that a low yield of product would result following this preparation, In particular, a successful application of this procedure would afford a relatively direct and inexpensive route to the sulfonic acid which is used as an azo dyestuff intermediate and could possibly find application in medicinal chemistry.

It was found that sulfonation and nitration of p-dichlorobenzene gave a high yield of the sodium-2-nitro-1,4-3 dichloro-benzene-6-sulfonate (91%) when using the …

Cuprous Oxide Rectification, Philip G. Cobb

Theses

It has been shown that cuprous oxide, when formed from a copper surface by suitable heat treatment, has remarkable rectifying properties towards alternating voltages applied through the oxide and copper. The purpose of our work was to investigate, the effect fully from all angles possible, and especially from those considerations affecting the constancy and permanence in the electric circuit.

The work ranged from furnace operation to tests of completed units, and further to the development of a theory explaining as completely as possible this rectifying property.

It soon became apparent, that here was ideal thesis material, and so, with proper …
