Organic sole of or tetravalent metal oxid and their use as additive in hydrocarbon compositions. |
摘要 |
<p>A new sol compsn. which comprises:- oxide particles of a tetravalent metal; an amphiphilic acid system, and a diluent in which the particles have a d90 no more than 200 nm, and the sol has at least one of the following characteristics:- the oxide particles are in the form of crystallite agglomerates (CeO2) which the crystallites have a d80 (pref. d90), measured by photometric counting (HR transmission electronic microscopy) of no more than 5nm, 90% of the agglomerates comprising 1-5 (pref. 1-3) crystallites. The amphiphilic system comprises at least one 11-50C acid and has at least one branching in the alpha-beta or gamma position to the acidic H. The use of the prods. as additives to gas oil fuels is also claimed.</p> |
