Sugar, cane, mixtures with liquid

Mixtures of Cane Sugar with Liquid Glucose. For calculations with mixed sugars, the copper-reducing power, or K value, is often required, i.e, the relative reducing power of carbohydrates and solutions thereof referred to dextrose equal to 100. Thus a syrup which contains 45 per... 

Cases where the phases are solutions (or mixtures) containing but one common component occur more frequently. Selective solution of a component from a solid mixture by a liquid solvent is known as leaching (sometimes also as solvent extraction), and as examples we cite the leaching of gold from its ores by cyanide solutions and of cottonseed oil from the seeds by hexane. The diffusion is, of course, from the solid to the liquid phase. If the diffusion is in the opposite direction, the operation is known as adsorption. Thus, the colored material which contaminates impure cane sugar solutions can be removed by contacting the liquid solutions with activated carbon, whereupon the colored substances are retained on the surface of the solid carbon.
