Abstract
Mixed aromatic/aliphatic oxyaluminum acylates wherein the ratio of the number of aromatic radicals to the number of aliphatic radicals ranges from 3:1 to 19:1 and a process for making such compounds. Also premix compositions useful in grease manufacture are provided along with methods for preparing new greases therefrom.
Claims25
Compounds of the formula ##STR9## and of the formula ##STR10## wherein R is selected from the group of radicals consisting of:
- Type (A):
- aliphatic radicals each containing from 10 to 38 carbon atoms, and
- Type (B):
- aromatic radicals each containing from 6 to 16 carbon atoms, and
- wherein, in any given group of such compounds, the mole percent of said Type (B) radicals ranges from 75 to 95% and the balance up to 100 mole percent thereof is said Type (A) radicals.
