Strontium fluoride flowsheet development studies for the waste packaging program

Description: It was demonstrated that the modified version of the Martin flowsheet can produce SrF/sub 2/ of acceptable quality using a simulated feed of the same composition as the anticipated packaging plant feed. By careful control of operating conditions, strontium losses in the process can be reduced to an acceptable level. Using a nonrepresentative radioactive feed (which contained impurities not present in the simulated feed) high strontium losses were encountered in the feed purification step, altho… more

PETN homologs

Description: High purity nitrate esters of the pentaerythritols can be successfully synthesized from correspondingly high purity reagents. The latter are not commercially available, but may be purified through molecular distillation and/or fractional crystallization from xylene. The isolated products are ultimately saponified to reagents of high purity. The nitration of high purity pentaerythritols using 97-100% nitric acid proceeds smoothly resulting in yields of the corresponding nitrate esters which are … more

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.

Slow PBX development. Quarterly report, October--December, 1971

Description: A total of nine batches of pressable baratol and pressable Composition B-3 were made and analyzed. One pressing was made for P/040 fabrication and test fire. The first P/040 plane wave lenses designed were fabricated and fired, yielding a center-leading average of 0.17 {micro}sec asimultaneity. The interface contour was redesigned and two lenses were fabricated and fired, resulting in center-lagging asimultaneity of 0.098 {micro}sec and 0.074 {micro}sec.

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

Description: Existing supplies of bis-trinitroanisole and picryl hydrazine were used to make 2 kg of bis-hexanitrohydrazobenzene. Development of the HNAB recrystallization process was temporarily stopped due to the need to produce a supply of the intermediate products (picryl chloride and HNHB). Purchase orders for DINOL and DNPIA required for synthesis of AFNOL were awarded.
