Solubility of some sodium soaps in pinene

  • Published:
Proceedings of the Indian Academy of Sciences - Section A Aims and scope Submit manuscript

Summary

  1. 1.

    Solubility curves have been determined over the temperature range 30° to 150° C. for sodium palmitate, stearate and oleate in pinene. The solubility of the three soaps decreases in the order NaOl>NaStr>NaP.

  2. 2.

    The solubility curves show a kink or change in direction at about 100° to 110° C. which is caused possibly by either the formation of colloidal micelles or a phase transition of the soap.

  3. 3.

    The regions of existence of solutions, sols, crystals, jellies, gels, etc., in the system sodium oleate-pinene have been indicated in a schematic partial phase diagram.
