Denatured alcohol Density

XII) Ethy Alcohol Solution. Since LA is very sensitive, it was shipped and stored at KOW wet with not less than 20% (usually 25-27%) of a 50 0.5% (by wt) denatured alcohol (Ref 9, p 57). Alcohol served as an antifreezing agent. The compn of an ale soln can be detd from the table, density vs % ale after detg the density by means of a Leach pycnometer standards2ed at 25°, using the following formula ... 

Small Areas Puddles of liquid must be contained by covering with vermiculite, diatomaceous earth, clay, fine sand, sponges, paper towels or cloth towels. Place the absorbed material into containers with a high-density polyethylene liner. Decontaminate the area with a fresh solution of HTH pool bleach in denatured alcohol (approximately 9 percent by weight) followed by decontamination with copious amounts of aqueous sodium hydroxide solution (a minimum of 10 percent by weight). Vigorous off-gassing may... 

The process described below for the estimation methyl alcohol in presence of ethyl alcohol has proved to be of great service, especially in the analysis of methylated spirit or denatured alcohol. The substance under examination is freed by distillation from dissolved matter and the density of the distillate determined so as to ascertain its approximate alcoholic content. The densities of ethyl and methyl alcohols are nearly the same consequently only quired. 

Fuel alcohol (denatured ethanol, which contains impurities such as methanol so that it is not potable) produces about llAOOBtu lb" (IBtu or British thermal unit is the amount of heat required to raise the temperature of 1 lb of water at its maximum density, 1°F, and is equal to about 252cal). Gasoline produces about twice as many British thermal units.
