A Determination Of The Decomposition Potential Of Sulfamic Acid And Certain Of Its Metallic Salts, Francis J. Shell
A Determination Of The Decomposition Potential Of Sulfamic Acid And Certain Of Its Metallic Salts, Francis J. Shell
Master's Theses
The present investigation of decomposition potentials, or the potential where continuous electrolysis begins, was suggested by a paper by Choguill (5) on the electrodeposition of some metals from solutions of their sulfamates. Sulfamic acid or amidosulfonic acid H2N•SO2•OH is a strong inorganic acid obtained from chlorosulfonic acid and ammonia, or by heating urea with fuming sulfuric acid. The latter process is now used on a commercial scale. The acid forms white or colorless non-hygroscopic crystals that are stable when dry but in solution at elevated temperatures it slowly hydrolyzes forming ammonium bisulfate.
The Reactions Of Ethyl Acetoacetate With Certain Halogen Derivatives Of Alcohols, Harold E. Sullivan
The Reactions Of Ethyl Acetoacetate With Certain Halogen Derivatives Of Alcohols, Harold E. Sullivan
Master's Theses
Chemical literature records many series of compounds produced by the acetoacetic ester synthesis, but in no instance is combination of the acetoacetic ester with the halogenated alcohols, of which the chlorohydrins are examples, mentioned. The products of these reactions are substituted derivatives of the· acetoacetic ester. These products yield, upon hydrolysis, hydroxy-ketones. These acids and ketones may serve as intermediates for synthesizing other compounds. Many compounds which have medicinal value, such as pyrazolones and other ring compounds, may be synthesized from the acetoacetic ester derivatives. 'This study of the reactions of the acetoacetic ester with certain halogen derivatives of alcohols …
