Determination Of The N-Terminal Amino Acid Residues On Polypeptides In Secondary Wastewaters, Edward L. Creecy Jul 1998

Determination Of The N-Terminal Amino Acid Residues On Polypeptides In Secondary Wastewaters, Edward L. Creecy

Chemistry & Biochemistry Theses & Dissertations

The N-terminal amino acid residues on polypeptides and proteins were determined in wastewaters prior to chlorination. The terminal amino groups'ere first derivatized with the well known derivatizing agent dansyl chloride, and then the resulting dansyl amino acid hydrolyzed from the peptide chain by a propionic acid/ hydrochloric acid mixture. The resulting dansyl amino acids were then separated and detected using reversed phase high performance liquid chromatography with fluorescence detection. The majority of N-terminal residues detected were the more polar amino acids. Concentrations ranged from 1 x 10-10 to 3 x 10-7 moles/liter. It is suggested that the shorter …


Approaches To A Generalized Synthesis For Hexaphenylbutadiene, Karena Kaye Linkenhoger Robinson Jan 1998

Approaches To A Generalized Synthesis For Hexaphenylbutadiene, Karena Kaye Linkenhoger Robinson

Theses, Dissertations and Capstones

This study was concerned with the attempted development of a generalized synthesis of hexaphenylbutadiene. Three methods were attempted: Michael Addition of cyanide to -phenylcinnamate followed by organolithium or Grignard addition; reaction of benzil with two moles of the Wittig reagent prepared from bromodiphenylmethane; reaction of two moles of benzophenone with the bisphosphorane prepared from 1,2- dibromo-1,2-diphenylethane.
