Ethyl alcohol specific heat

Nitromaltose (Maltose octonitrate), Ci2Hi403(0N02)8 Maltose octonitrate,60- 70 glistening needles from methyl alcohol, melts with decomposition at 164-165°. If heated quickly, it puffs off at 170-180°. It decomposes slowly at 50°. If fused and allowed to solidify, it has a specific gravity of 1.62. It is readily soluble in methyl alcohol, acetone, and acetic acid, difficultly soluble in ethyl alcohol, and insoluble in water. It reduces warm Fehling s solution more rapidly than nitrosucrose. 

This invention relates to alcoholic drinks, specifically a technological process for making ethyl alcohol from Jerusalem artichoke tubers. Processed tubers are heated with mineral acid to complete saccharification, and excessive acidity is neutralized with CaC03 prior to fermentation and distillation. 

The specific heat of mixtures of liquids can rarely be calculated additively from the specific heats of the components. There is generally a considerable deviation from the law of mixtures, and the calculated value is always larger than one would expect. Mixtures of hquids which are closely related chemically, such as ethyl and methyl alcohol, chloroform and carbon disulphide, behave normally mixtures of water with alcohol, or of alcohol with other organic hquids, show large deviations. It is noteworthy that heat is evolved on mixing these hquids, an indication that chemical combination also is taking place. This is probably the reason for the alteration in the heat capacity, since the specific heat of liquid chemical compounds cannot be calculated additively from the specific heats of the components. The regularities shown by sohd bodies do not hold even approximately for hquids. 

The effects of storing lead azide for long periods in 50 50 water-ethyl alcohol mixtures have been investigated by impact sensitivity tests. In a specific instance [43] dextrinated lead azide which had been stored for about 25 years was tested, and no significanl change in sensitivity to impact or heat was detected when compared to freshly made material.
