TABLE 136.-Velocity of crystallization according to Kukharenko, and concentration data for pure sucrose in water

[Concentration data for solutions of pure sucrose in water for 10-degree intervals of temperature and for 0.005-intervals of Kukharenko's coefficient of supersaturation, k=s'is, as based upon Herzfeld's table of solubilities of sucrose, together with the corresponding velocities of crystallization according to Kukharenko, where K has the dimensions mg/(m2×min). The "hypothetical yield at 20°, #20," is the quantity given in column 13 but expressed as a percentage of the total quantity of sucrose present in 100 g of water, as given in column 11. The "oversaturation, e20," in column 15 is the same quantity expressed as a percentage of 203.9 g, the weight of sucrose required to saturate 100 g of water at 20°, while "e" in column 16 is the percentage of sucrose dissolved in excess of saturation requirements at the temperature t; or, stated as an equation, e=100(c'-c)/c. Therefore, e, is the quantity given in column 12 expressed not in grams but as a percentage of c, when the unit weight of water is 100 g. The symbols used in the various equations have the following significance:

c' weight of sucrose dissolved in unit weight of water in the given solution.

C=weight of sucrose required to saturate unit weight of water at the temerature f, as derived from Herzfeld's table of solubilities.

m2= total area of the crystal surface, expressed in square meters.

ing weight of sucrose deposited on the crystals of m2 surface area, expressed in mg.

min-time required to deposite the given weight of sucrose, expressed in minutes.

s' percentage of sucrose contained in the given solution.

8 percentage of sucrose contained in a solution which is just saturated at the temperature t.]
