Szilard-Chalmers Reactions, Anita Camilli Mewherter

Honors Theses

Since discovery of radioactivity at the turn of the century, the use of radioactive isotopes has become increasingly significant to research in the fields of chemistry, biology, botany, and medicine. An important use of these radioactive isotopes is the tracer or indicator method. For example, a portion of radioactive potassium may be added to a sample of of stable potassium to be studied. The fact that a given isotope is radioactive does not, in most cases, affect its chemical properties. The presence of the active isotope allows the potassium now to be followed through a chemical or biological process. This …

Electrodeposition With Graded Cathode Potential, William Mairs Earnest

Honors Theses

In a constant current electrolysis, which is the unusual method of determining a substance quantitatively by electrodeposition, a single metal, in solution, is plated out on the cathode of the electrolysis cell. The current is maintained fairly constant by adjustment, little attention is paid to the potential applied to the cell. This method may be used if there is only one metal in solution, or it may actually be used to separate two metals if one lies above and the other below hydrogen in the electromotive series. In this case, hydrogen is evolved at the cathode after the deposition of …

A Study Of The Reaction Of Portland Cement With Certain Acids, Robert Alfred Laudise

Honors Theses

Portland cement was treated with various concentrations of hydrochloric, acetic, and sulfuric acids. The reaction products, mixed gels of SiO2, Al203, and Fe2O3, were examined for commercial possibilities. Liquid absorption of organic dyes was used as a criterion of surface activity. When 10gm cement was reacted with 100m.l. of acid solution, it was found that the reaction went to completion at 3 molar HCl, 3 normal H2SO4, and about 7-9 molar HAc. The best absorbers for methylene blue were formed by the reaction of 2.5-3 molar HCl and 6-9 molar HAc. The absorption of some of these gels were carefully …

The Inhibition Of The Thermal Polymerization Of Styrene, William Russell Stoll

Honors Theses

In continuing the work of Cohen and Opitz the percent polymer formed by the inhibition of the thermal polymerization of styrene with chloranil at one hundred degrees is determined to be 0.0025%. The first polymer is precipitated by absolute methanol approximately twenty minutes before the end of the induction period. For polymer determination an analytical method is developed, which is applicable for concentrations between 0.001% and 0.022% by weight measures the solution turbidity after precipitation from the monomer. This method can be extended to 0.08% polymer. Polymer percentages to be measured in this manner greater than 0.02% were diluted with …

Thallium Dithizonate, Bruno Jaselskis

Honors Theses

Attempts to establish a useful dithizone method in the determination of thallous ion have been carried on at Union College by Snyder (19). Because the previous work had not produced satisfactory results and because in general thallous dithizonates have not been studied, the following work, under Dr. W. G Ewing’s guidance, was undertaken.

The Preparation, Properties And Reactions Of B-Diethylaminoethoxy-Methylsilanes, Edward G. Tajkowski

Honors Theses

In the course of work on the application of silicones to textiles and paper, chiefly to impart water repellency thereby, it has been found that the most desirable method for industrial operations is from water solution. Methods for preparing emulsions of silicones have been developed and such materials are available commercially. However, it would still be of interest to obtain a material which is directly water soluble and which is either a silicone itself, or can be simply and easily converted to a silicone in situ.

These facts were brought out by Dr. D. P. Spalding (1) in a discussion …

The Effects Of Ph And Salts On The Viscosity Of Gelatin Sol (The Hofmeister Series), Frank Z. Pollara

Honors Theses

The purpose ot this investigation was to accurately determine the effect of monovalent sodium salts on the viscosity of gelatin sol as a function of pH and to establish the Hofmeister series by this method.

The gelatin investigated was derived from pigskin and the salts used were NaCl, NaNO3, and NaI, of various concentrations. In order to justify and make reasonable the conclusions reached in this investigation, these conclusions must be viewed in the light of the work previously done by other investigators of this field.

With this in mind, a short historical survey of the origin and development of …
