Synthesis Of Imidazolines, Diazepines, Triazepines And Imidazolidones From A 1, 2-Diamine And 1, 1-Dicarboxylic Esters., Irwin J. Pachter

Chemistry and Chemical Biology ETDs

In view of the inconclusive character of much of the above mentioned work, a further investigation of the reactions between 1, 2-diamines and dicarboxylic esters of the type CH3CH2OOCXCOOCH2CH3(X=CH2, CHR, NH) seemed warranted. In our present investigation we were guided by three main considerations.

Synthesis Of 2-Phenyl-2,1,3-Triazole-4-Carboxaldehyde And Some Derivatives, Gene Sumrell

Chemistry and Chemical Biology ETDs

It was decided in this problem to prepare 2-phenyl-2,1,3-triazole-4-carboxaldehyde (III) as a starting material by the method suggested by Hann and Hudson and run a number of typical aldehyde reactions with it. The preparation of (III) involved: (1) The hydrolysis of sucrose to form glucose and fructose; (2) conversion of these two sugars to D-glucose phenylosazone (I), by reaction with phenylhydrazine; (3) transformation of (I) to D-glucose phenylosotraizole (II), by the action of hot aqueous copper sulfate; and (4) oxidation of the side chain from (II) with sodium periodate, forming (III).

The reactions selected were: (1) the Grignard reaction; (2) …

The Conversion Of Certain Amino Acids To Carbohydrate In Normal Animals, Bergere Alfred Kenney

Chemistry and Chemical Biology ETDs

The glycogenic effects of the individual amino acids, in the metabolism of normal animals, are by no means well defined. IN some cases, as in those of alanine and glutamic acid, the tendency of the acid to form glucose is generally accepted; in others, of which leucine and lysine are good examples, there is definitely no glucose formation; in still other cases, namely those of glycine and cystine, the contradictory nature of the results obtained by different investigators gives anything but a clear picture of the situation...

It is the purpose of this paper, therefore, to attempt such an estimation …

A Chemical And Biological Study Of The Waters Of Elephant Butte Reservoir As Related To Fish Culture, John Greenbank

Chemistry and Chemical Biology ETDs

The purpose of this preliminary survey was to determine, in so far as was possible in the limited time that was available, the general suitability of the waters of the reservoir for fish life, and to make such recommendations for future fish culture policy as seemed to be advisable. AN unpublished report of this preliminary survey was written by Dr. Hazzard.

Public Water Supplies Of New Mexico, Kenneth F. Priest

Chemistry and Chemical Biology ETDs

Distribution of population in State. The estimated population for the State of New Mexico for the year 1930 was 423,300. A close observation of the population centers shows them to be scattered over a wide range of territory. The largest city, Albuquerque, has approximately 26,000 citizens. The next sites, according to the 1930 count, are three in number, Santa Fe, Roswell, and Clovis. The remaining population including rural districts do not number over eight thousand people.
