ABSTRACT OF THE DISCLOSURE Metallo-organic compositions soluble in oils and hydrocarbon solvents, of a high transitional metal content and highly overbased character, are prepared from sources of transitional metals (or of transitional in conjunction with non-transitional metals) reacted with mixed organic acids com- prising at least one monocarboxylic acid and a second acid, either a sulfonic acid or a different molecular weight mono- carboxylic acid. Formation of the complexes requires the use of excesses of metal over acids, and the use of an oxygen- supplying material such as air, regardless of whether the metal source be a free metal, an oxide or a hydroxide. Alkoxyalkanols or glycols may be used in addition to the required acids. These compositions comprise (1) a polynuclear core of a normally in- soluble metal oxide or hydroxide which is crystalline by X-ray and electron diffraction observation, with metal hydroxyl car- boxylate groups (and when present, sulfonate or alkoxyalkanol or glycol groups) ionically and hydrogen bonded to the core element atoms, and additional acid groups having an unbound association with a core and its bonded groups; (2) ultimate particles having structure with minimum average undissociated molecular weight of about 104; and (3) a ratio of total moles of metal to total moles of organic acid moieties being greater than 1 to 1. The major application for these complexes will be as catalysts for a variety of chemical operations in which prior art metal soaps currently are used. The use of the complexes results in certain advantages in addition to the high metal con- tent. The complexes are not only soluble in organic media, but they also exhibit some of the important properties of the metal oxides used in heterogeneous catalysts. Consequently, they will be useful in bridging the gap between heterogeneous and homo- geneous catalysts by supplying advantages common to each.
