AFNOL preparation. Quarterly report, July--September, 1971

Description: A nominal 15-pound batch of FEFO plasticized AFNOL was in preparation. Both the first and second esterifications were completed. (An equipment malfunction resulted in a loss of the product and the reaction vessel). The paper describes the preparation procedures and the malfunction.

AFNOL synthesis. Quarterly report, October--December, 1971

Description: Five batches of unplasticized AFNOL, each approximately one pound, were synthesized using 4,4-dinitropimelic acid as the starting material. Two 10 g batches were completed prior to the pound batches to assure the usability of the acid chloride. Characterization of each of the larger batches was by differential thermal analysis (DTA), infrared spectrophotometry (IR), and cure tests. Some characterization was also done on the commercial chemicals used in the synthesis.

ANFOL synthesis. [Quarterly report], April--June 1971

Description: A new method was developed for chlorination of 4,4-dinitropimelic acid with PCl{sub 5} using a Soxhlet extraction apparatus as the addition vessel. Acid used was that reclaimed from the purification of the crude acid chloride of 4,4-dinitropimelic acid supplied by LRL. Synthesis of FEFO plasticized AFNOL has been scaled up to a nominal 30-pound batch. Small batches and cure tests were run prior to the scaleup. Cure rate of the AFNOL system was followed by infrared spectrophotometry. The tempera… more

Application Of Biometrical Genetics Techniques To Irradiated And Non- Irradiated Populations Of Corn To Provide Information On Nature Of Gene Action Involved In The Inheritance Of Quantitative Traits And In Heterosis. Final Report, 1970.

Description: The purpose of this research was to extend out quantitative genetic investigations into some of the more basic aspects of genetic variation and heterosis observed in irradiated and non- irradiated populations of corn in order to determine more precisely how genes do act and interact to produce their observed cumulative effects.

Argonne Radium Studies.

Description: The ultimate goal of the study of the long- term effects of radium in humans is to delineate the dose- response curve. The shape of this curve is of great importance in setting the maximum permissible amount of any radioactive material to which humans may be exposed. Various theories of clinical effects versus dose have been postulated.
