This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
1.344 at 20.0 °C [1] ... Gas properties Std enthalpy change ... Vapor-liquid Equilibrium for Acetonitrile/Methanol [4] P = 760 mmHg BP Temp.
The best known of these is the ternary azeotrope formed by 30% acetone, 47% chloroform, and 23% methanol, which boils at 57.5 °C. Each pair of these constituents forms a binary azeotrope, but chloroform/methanol and acetone/methanol both form positive azeotropes while chloroform/acetone forms a negative azeotrope.
Here is a similar formula from the 67th edition of the CRC handbook. Note that the form of this formula as given is a fit to the Clausius–Clapeyron equation, which is a good theoretical starting point for calculating saturation vapor pressures:
A comparison of S N 1 to S N 2 reactions is to the right. On the left is an S N 1 reaction coordinate diagram. Note the decrease in ΔG ‡ activation for the polar-solvent reaction conditions. This arises from the fact that polar solvents stabilize the formation of the carbocation intermediate to a greater extent than the non-polar-solvent ...
One drink is defined as 1.5 ounces of liquor, 12 ounces of beer or 5 ounces of wine. Taub-Dix points out that alcoholic cocktails are often made with ingredients like mixers, syrups and juice drinks.
Acetonitrile has only modest toxicity in small doses. [11] [19] It can be metabolised to produce hydrogen cyanide, which is the source of the observed toxic effects. [9] [20] [21] Generally the onset of toxic effects is delayed, due to the time required for the body to metabolize acetonitrile to cyanide (generally about 2–12 hours). [11]
