Abstract
A method of preparing a metal oxide which is dispersible in organic matrices such as apolar organic liquids wherein a product mixture is formed by adding sol of the metal oxide to an aqueous suspension of a sulfonic acid modifier, the modified metal oxide being recovered from the product mixture
Claims17
A method of preparing a metal oxide which is dispersible in organic matrices comprising:
- forming a reaction product mixture by adding an aqueous sol of a metal oxide to an aqueous suspension of a sulfonic acid modifier having the structure
- X(SOyM)n
- wherein X is an organic moiety, M is a monovalent cation, y is 3 or 4, and n is an integer reflecting the number of —SOyM groups bonded to the organic moiety, to form a modified metal oxide;
- and
- recovering said modified metal oxide from said reaction product mixture.
