    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.

    33、3 Wetting Properties and Low-Temperature Adhesion: Two polished and alkaline-cleaned panels of AMS 5044 steel, or equivalent, nominally 1/16 x 4 x 2 inches (1.6 x 102 x 51 mm), shall be immersed for one minute in compound at 205 to 210 F (96 to 99 C), withdrawn, cooled to room temperature, and suspe

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

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
