Abel or Kl-Starch Test at 65.5°C. A brief description is given in Vo 1 of Encycl, p A2-L, while a detailed description including the drawing of apparatus and prepn of Kl-starch paper, is in BurMinesBull 51 (Ref 1, pplO—12) (See also Ref 14, pp5-14 5-15)... 

Stability. The Dynamites shall cause no discoloration of Kl-starch test paper for a minimum period of 10 mins, when tested at 82.2il.O°G as specified in 4-3-3. p4 of M1L-D-60365(MU) (Code No 03001). A brief description of this test, known as Abel s Test, is given in Vol 1... 

Abel s Test or Kl—Starch Test was designed by Sir F. A.Abel to determine the stability of propellants and explosives. It involved heating a small sample of an expl in a test tube closed with a stopper provided with a hook on which is suspended a strip of KI—Starch paper, moistened at the upper half with 50% glycerin in water. The tube is heated in a constant temp bath and the time necessary to produce a slight brownish (or other) coloration at the border between the moistened and dry areas of the indicator paper is observed. The longer the time required the greater the stability of substance under test. The test is usually conducted either at 65.5° or 82.2°, but other temps may also be used. More detailed descriptions of the test are given under propellants and under some expls, such as TNT... 

Kost Value or Brisance Value of Kost will be discussed in Vol II, under Brisance Value of Knst Kl-Heat Tests or Kl-Starch Tests, See Abel Test, p A2 of this volume... 

If the test is still positive, thiosulfate solution should be added until a negative test is attained. The checkers found EM Quant Peroxide Test Strips obtained from EM Science to be more sensitive than conventional Kl-Starch test paper. 

Weigh to 0.1 mg 2.5 to 3 g of the purified aniline, transfer to a 1 1 volumetric flask contg 900 ml distd w and 50 ml coned HC1. Fill the flask to the mark and shake it until the soln is uniform. Transfer a 100 ml aliquot to a 400 ml beaker, add 10 ml coned HC1 and cool the soln to 15°- Titrate slowly with the 0.2A1 KBr03-KBr soln. Near the end of titration, test, after the addition of each drop of the soln, by spotting Kl-starch test paper. The end point is indicated by the It blue coloration which can be duplicated after a 2-min period. When the end point is reached, an addnl drop of the KBrOj KBr soln will color the mixt yel, thereby corroborating the end point indicated by the test paper Calculate the normality of KBr03-KBr by the following formula ... 

Abel s Test(KI Heat Test or Kl-Starch Test) (Epreuve d Abel, in Fr.) A brief description is given on pA2 of this volume. The test is also described in TM 9—1910(1955)>57—60... 

Isolation of Product. Using a Pasteur pipet, add a saturated, aqueous sodium bisulfite solution dropwise to the reaction mixture until the solution gives a negative Kl-starch test.
