16、t this procedure two times, making a total of three extractions. Using an eye dropper, transfer to the crucible enough alcohol to thoroughly wet the sample and wash the crucible walls. Aspirate until the odor of alcohol is no longer detectable and dry the crucible in an oven for 30 minutes at 60 + 5
17、OC. Cool in a desiccator and weigh. Record this weight as Weight B. Reserve the crucible and residue for the basic lead styphnate determination. Correct for the percentage of basic lead styphnate in the water extract as follows: Transfer the filtrate and washings quantitatively to a 100 ml. calibrat
18、ed volumetric flask, washing the beaker thoroughly with distilled water and dilute to the mark. Using a calibrated pipette, transfer a 10 ml, aliquot of this solu- tion to a second 100 ml. calibrated volumetric flask and dilute to the mark with distilled water. Transfer a portion of this solution to
19、 a corex glass spectrophotometric cell having a width of approximately 1 centimeter (cm) and determine its op- tical density at a wave length of 410 millimicrons. Use as reference a similar cell containing the same proportion of water saturated with lead azide and alcohol as in the sample colution.
20、Since the cell which holds the lead styphnate solu- tion is not identical with the reference cell, correct the optical density obtained as described above for the difference in the amount of light which the two cells scatter and absorb. To do this, fill both cells with a solution of water and alcoho
21、l, and measure at a wave length of 410 millimicrons, the optical density of the cell which originally contained the basic lead styphnate solution. Caluculate the percentage of basic lead styphnate in the filtrate on a dry basis as follows: Basic lead styphnate found Percentage Pb = 4.48 (A-B) in bar

Tetracene: The wet residue obtained in the determination ot basic lead styphnate shall be washed three times with alcohol, dried in an oven maintained at 60 + 5OC, for 30 minutes, cooled in
25、a desiccator and weighed. Te dried residue in the crucible shall be transferred to a 125 ml. beaker with a stream of water; 25ml. of water shall be added, and the contents of the beaker boiled on a hot plate for 5 minutes. The contents of the beaker shall be quantitatively transferred into the same
26、crucible, and the residue in the crucible washed three times with boiling water and finally with alcohol. The crucible and contents shall be dried in an oven maintained at 60 + 5OC for 30 minutes, cooled in a desiccator and weighed, The percentage of tetracene in the specimen shall be calculated as
27、follows: Tetracene, percent = (C-DI-100 W 23 Licensed by Information Handling ServicesMIL-P-63297 13 M 999%b 03Ll7Ll3Ll MIL-P-63247 (AR) where : C = Weight of crucible and residue after extraction with saturated ammonium acetate solution, g.
