Abstract

Interphase Distribution of Pectinate Calcium and Alginate Calcium in a System of Two Immiscible Liquids

Author(s): Kajsheva NS, Kajshev AS

In comparison with the sugar beet pectin and sodium alginate, was studied interphase distribution of pectinate calcium and alginate calcium in the system "water: octanol-1" (1:1) at different temperatures. On the basis of the equilibrium concentrations of pectin, sodium alginate (technique neutralize), pectinate calcium, calcium alginate (complexometry) identified in the aquatic and oktanole phases, graphically the calculated degree of Association of compounds in non-polar solvent, the calculation method of the distribution coefficients. The dependence between the process temperature and the degree of Association management: Video for sodium alginate, the inverse of pectin and pectinate of calcium; no effect on alginate calcium. Direct dependence between the temperature and distribution coefficients for pectin, pectinate calcium, alginate calcium, the alginate sodium. In descending order of the distribution coefficients of the substances in the following order: pectin>pectinate calcium>alginate calcium>alginate sodium. Calculation of thermodynamic functions (enthalpy, entropy, Isobaric-isothermal potential) according to the established distribution coefficients and known formulas showed a decisive contribution to the change of the Gibbs free energy entropy factor. The data obtained allowed to conclude that under standard conditions the spontaneous transition of pectin, pectinate calcium, alginate calcium from the polar phase to nonpolar phase, and for alginate sodium this transition can be carried out in the presence of activators of the process.
