This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1916 edition. Excerpt: ...fluid products, such as carpeting mediums, the residue from the volatilization test may be subjected to the float test if too soft for its penetration to be determined. This is particularly advisable where the float test can be made upon both the original material and its residue. In some cases the volatilization test is made at other temperatures than 1630 C. Thus the tenDEHYDRATION--DETERMINATION OF WATER. 75 dency of a material to harden very rapidly after use is shown by a test at 1000, 1050, or u00C. If the test is to be made upon a tar product, a relatively low temperature should be used, as 1630 C. is unnecessarily severe for tars, owing to the fact that it is never necessary to heat them to this temperature during use, and if they are so heated they are apt to be seriously injured. In general, for a given type of residual product, the loss by volatilization decreases with increase in specific gravity, flash point, and specific viscosity or float test, and decrease in penetration if it is a semisolid or solid. DEHYDRATION--DETERMINATION OF WATER Equipment: 1 800 cubic centimeter cylindrical copper still with ring burner and rubber tubing. 1 Bunsen burner. 2 iron stands. 2 small iron clamps. 1 iron ring support. 1 long piece of glass tubing, bent for a condenser. 1 special form separatory funnel with graduated stem. Method.--When it is desired to dehydrate a bituminous material prior to making other tests or to determine the percentage of water which it contains, a cylindrical copper still with ring burner, as shown in Fig. 22, will prove convenient. From 250 to 500 cubic centimeters of the material are accurately weighed into the still and a thin paper gasket tightly clamped between the still and still head. The apparatus is then...
