30、thods: 4.5.1 Nonvolatile Content: Weigh approximately 5 grams of compound to the nearest milligram into a tared evaporating dish. Heat the dish and contents in an oven at 221 to 230 F (105 to 110 C) for 24 hours 0.25. Cool to room temperature, reweigh, and calculate the nonvolatile content using Equ
31、ation 1.(Eq. 1)where:A = weight of residue, gramsB = original weight of sample, grams4.5.2 Stability: A sample of compound shall be placed in a test tube, heated to 220 F 2 (104 C 1), and maintained at that temperature for 60 minutes 5. Tube and compound shall be cooled to room temperature, held for
32、 60 minutes 5, further cooled to -40 F 2 (-40 C 1), and maintained at that temperature for 60 minutes 5. Tube and compound shall be reheated to 220 F 2 (104 C 1) and maintained at that temperature for 60 minutes 5. Compound, after returning to room temperature, shall be examined for homogeneity.4.5.

34、nded vertically in an atmosphere of not more than 60% relative humidity at 77 F 7 (25 C 4) for 24 hours 0.5. Panels shall be cooled to 0 F 2 (-18 C 1), and maintained at that temperature for 60 minutes 5. While at 0 F 2 (-18 C 1), four parallel scratches about 1/8 inch (3.2 mm) apart and 1 inch (25
35、mm) long shall be made in the compound film with a pointed knife blade; four similar scratches which intersect the first four at right angles shall also be made. There shall be no flaking of the film within the area bounded by the scratches.4.5.4 Rosin: Add 10 grams of compound to 25 mL of 95% ethyl
36、 alcohol and heat the mixture to boiling. One or two drops of the solution of compound in alcohol shall be placed on a porcelain spotplate with three or four drops of acetic anhydride. Add one drop of chemically pure sulfuric acid. A rose-violet coloration, or a flash of purple produced when the aci
37、d meets the anhydride, indicates the presence of rosin.4.5.5 Acidity (Inorganic Acid): A 25 to 50-gram sample of compound shall be introduced into a 250 mL separatory funnel followed by 100 mL of boiling distilled water. The funnel shall be shaken vigorously and, after compound and water have separa
38、ted, the water layer shall be drained into a 500 mL casserole. Compound in the funnel shall be washed twice more by vigorously shaking with 50 mL portions of boiling distilled water. After each washing and separation, the water layer shall be drained into the casserole. One drop of 1% solution of ph
39、enolphthalein shall be added to the 200 mL of accumulated water and the water boiled. A change in color to pink indicates the solution is alkaline. If addition of phenolphthalein causes no change in color, two drops of 0.1% solution of methyl orange shall be added. A change to red or pink indicates
