Since there is an approxiaate exponential relationship between retention tine and solute boiling point under isotheraal conditions, it is iapossible to establish a suitable tenperature for the analysis of nixtures with a boiling point range exceeding ca. 100 C. This is coaaonly referred to as "the general elution...

The effect of the solute on the solution boiling point is easy to see from the diagram. Recall that the boiling point of a liquid at a given pressure is the intersection of a horizontal line at that pressure with the vapor-liquid equilibrium curve. At pressure Po, the pure solvent boils at temperature Tbo, while the solution boils at a higher temperature. Tbs.

For the same vacuum level, a crystallizing slurry will have a higher temperature than predicted for the pure solvent because the vapor pressure of the solvent is reduced by the presence of the solute (boiling point elevation). For adiabatic crystallization with the contents temperature as the input to the master control loop, the same temperature profile appropriate for crystallization by jacket cooling would apply here. However, the capability of the vacuum source and the line pressure drop should be considered in conjunction with the boiling point elevation to ensure that the desired final temperature can be met. If this is not satisfied, the desired yield may be achieved by removing some of the distillate, provided the saturation of an impurity is not reached. For most... 

Dutrizac has reviewed (4) the dissolution of zinc sulphide minerals in acidified ferric sulphate solutions. The results suggested that the important parameters involved are temperature and ferric ion concentration, and that the dissolution rates are rapid, at least near the solution boiling point. The reaction involved when using ferric sulphate solutions can be...
