Some Studies in Coupling of Aliphatic Nitrocompounds
The object of this thesis was the production and isolation of a new compound. . . . this problem was set forth by Merck and Co. because they believe that this compound may have properties similar to sulfanilamide. [From ...
An Attempt to Investigate the Reduction of Ruthenium Tetroxide by Potentiometric Methods
The titration curve for osmium tetroxide is similiar to the one obtained for ruthenium tetroxide becauee there is a minimum on each curve and the potential increases with each addition of
HCl. . . . Another point of ...
An Investigation of the Synthesis of [delta]9,10 Octal-1-one
The synthesis of [delta]9,10 octal-1-one has been begun in large quantities. The intermediate , methyl-[gamma]-(1-cyclohexenyl)-[gamma]-oxobutyrate has been obtained in workable amounts. A study of the use of semicarbazones ...
The Synthesis of Certain Substituted Sym-Diphenylcarbazides
It is perhaps advisable here to give a complete resume of the reactions involved in these syntheses. In all cases, a substituted aniline was the starting product which was diazotized with NaN02 in acid solution at a ...
Thesis in Chemistry [Double Cesium and Rubidium Salts of Lead Tetrabromide]
Salts in which lead is quadrivalent are comparatively unstable and usually they readily pass over into the corresponding compounds in which the lead is divalent. Salts of Hexa-chloroplumbic acid 2Hcl. Pb cl4 are known and ...
A Selected Oxidizing Reaction of N2O4 and a Comparison of the Decomposition of Certain Organic Compounds
This is essentially a repeat of I. E. Shillington's original reaction. [From concluding section]
Thesis on Concrete
The three investigations made are: 1. Effect of surface area on strength of concrete. 2. Consistency test: ie. Variable water ratio. 3. Density test. [From introductory section]
Thesis on Gypsum
The subject of this thesis is to try to prove that dead burnt gypsum will set if it has a nucleui to set around and for this nucleui to be furnished with a given % of either gypsum or plaster of Paris. To confirm the ...
Improving Mn(II) Remediation from Coal Mine Drainage by Passive 'Myco-Zeolite' Systems (thesis)
Coal mine drainage (CMD) is a pervasive issue across Appalachia and contaminates watersheds and drinking water with difficult-to-remediate metals like manganese (Mn). Current passive treatment methods for remediating Mn ...
Some Investigations of the Preparation of 4-(4-carboxyphenyl)semicarbazide and Its Camphor Derivative
At present the series of reagents available for the resolution of optically active carbonyl compounds shows some definite inadquecies. The investigations discussed in this thesis were undertaken to fill these gaps. [From ...
