Volumetric Variations in Sucrose Solutions and Equations That Can Be Used to Replace Specific Gravity Tables

Volumetric variations of sucrose molecules in aqueous solutions (relative to its crystaline) form were calculated from recently corrected sucrose specific gravity tables. This revealed an initial expansion when going from the crystaline to the solution state up to approximately 22°Brix, where expansion began to decrease, until 66°Brix, beyond which the molecular volumes in the crystaline form exceeded those in the solution phase. From the new tables, regression equations were derived using a multicurve fitting program for the density, weight/gallon, and pounds sucrose/gallon. These equations, which were shown to be capable of replacing the tables, would be of value in computer programming for industrial applications.
