Abstract
Study of stability oversaturation sodium formate solution
Incoming article date: 02.06.2015Sodium formate is quite popular products in industries. Currently, there is no independent production NаНСОО, because it is synthesized in the production of pentaerythritol and an additive product of this technology. For the production of the required quality sodium formate it is necessary treatment of the product. It is known that the crystallization processes are widely used in the technology of reactive substances qualifying, and the first stage of polythermal crystallization largely has a significant impact on the quality of the crystalline product. In the article the influence of hydrodynamics, cooling rate, the saturation temperature and concentration of pentaerythritol on supersaturated sodium formate solutions to overcooling was shown. The mathematical equations that valid describe the revealed features of the process have been received. The dependences should be considered in treatment technology of sodium formate crystallization method.
