Summary

  1. 1.

    The properties of cCa greases based on both narrow and especially wide SFA fractions depend less on the molar ratio of the low- and high-molecular weight acids than for cCa greases based on soaps of individual carboxylic acids. The optimum molar ratio of HAc to the narrow SFA fractions is approximately 2∶1 while for wide C10–C20 SFA fractions it is 1.5∶ 1, which is lower than for individual carboxylic acids (3∶1).

     
  2. 2.

    A cCa soap of SFA fractions has a reduced thickening effect compared with the soaps of individual carboxylic acids. They surpass the greases thickened with the cCa soap of individual carboxylic acids in a number of properties (viscosity-temperature behavior, colloidal stability). Both wide and narrow SFA fractions are promising raw materials for preparing cCa greases.
