18、5.1.1 Reagents - Toluene Solution. Preparation of Saturated Toluene Solution. Add an excess quantity of RDX (about .5 9.) to 1 liter of Toluene and stir the slurry mixture for a minimum of 2 hours (room temperatue) with a magnetic stirrer. Store the Toluene slurry mixture over the excess RDX. Filter

19、 the slurry mixture prior to use. 4.6.1.2 Preparation of sample. Spread the sample in a thin layer on a suitable Petri dish (100 X 15 mm). Place sample on Petri dish in a vacuum-oven at 60+2oC for two (2) hours, or until constant weight is obFained. 4.6.1.3 Procedure. Weigh accurately (to nearest 0.

20、1 mg), approximately a 10 g. portion of the dried sample and quantitatively transfer the sample into a 100 ml. Erlenmeyer flask. Add 50 ml. of the filtered Toluene solution to the flask. Stopper the flask and place the flask on a steam bath for 3 minutes and heat flask with contents. Remove flask fr

21、om steam bath and place flask in a wrist-action shaker. Shake for 30 minutes. Quantitatively filter the contents of the flask through a clean, tared sintered glass crucible, medium porosity, 30 ml. Use five 15 ml. portions of the toluene solution to rinse the flask to assure quantitative transfer. P

22、our each 15 ml. portion of the toluene thru the crucible. Use suction for the filtering operation. Dry the crucible and contents for one (1) hour in a vacuum oven maintained at 7OOCt2OC. Remove crucible and contents from the oven and allow to cool in a desiccator. Reweigh the crucible and contents.

24、t of sample, g. . 4.6.2 VC Copolymer. Calculate the percent VC Copolymer by subtracting the value obtained in 4.6.1.4 from 100.0%. 4.6.3 Calcium Stearate. Quantitatively transfer an accurately weighed portion of the sample (approximately 5g. weighed to nearest 0.1 mg) to a 150 ml. beaker. Concurrent

25、ly with this determination, conduct a blank determination without the sample but with all other materials. Add 30 ml. of concentrated hydrochloric acid (37-38%) to the beaker, cover with a watch glass, and heat beaker and contents an a steam bath for 15 minutes. Stir the contents of the beaker, occa

26、sionally, with a stirring rod while heating. After the 15 minutes, add an additional 30 ml. of concentrated hydrochloric acid, heat on steam bath and stir occasionally. While on steam bath, wash the cover glass and sides of the beaker with distilled water. Add, additional distilled water to the beak

27、er to give a total of approximately 100 ml. solution. Remove watch glass and continue heating the solution on the steam bath for an additional 15 minutes.
