Abstract: PCT No. PCT/EP96/02928 Sec. 371 Date Jan. 13, 1998 Sec. 102(e) Date Jan. 13, 1998 PCT Filed Jul. 4, 1996 PCT Pub. No. WO97/03946 PCT Pub. Date Feb. 6, 1997The invention relates to the preparation of organic nitrogen compounds, in particular of aminoalkanes, alkyloximes, alkylnitrones or mixtures thereof, which have only one nitrogen-functional group and no alcoholic hydroxyl groups in the molecule, from nitro-containing reaction products of polymers of C2-C6-olefins with an average degree of polymerization P=5-100 with nitrogen oxides or mixtures of nitrogen oxides and oxygen by hydrogenation of these reaction products. The invention also relates to particular mixtures of such aminoalkanes, alkyloximes and/or alkylnitrones and to individual compounds of these types themselves. The designated products are suitable as additives to fuels and lubricants.

Abstract: Catalyst suitable for hydrogenation of organic cpds., comprises (all based on total wt. of catalyst); (a) 80 wt.% nickel (calculated as nickel oxide); (b) 10-25 wt.% of silicon (calculated as zirconium oxide; and (d) 0-10 wt.% of aluminium (calculated as aluminium oxide). The amt. of silicon dioxide and aluminium oxide is at least 15 wt.%. The catalyst is prepd. by; (2) adding an acidic aq. soln. of nickel-, zirconium- and opt. aluminium salts to a basic aq. soln. or suspension of silicon cpds. (and opt. aluminium cpds.), so that the pH of the resulting mixt. drops to at least 6.5; (2) adding a further basic soln. to bring the pH to 7-8; and (3) isolating the pptd. solid, which is then dried, formed and calcined.

Abstract: A gasoline-based fuel composition with a sulfur content of not more than 150 ppm containing small amounts of fuel additive(s) (I) with a detergent or valve seat wear-inhibiting action, in which (I) contain hydrophobic hydrocarbon residue(s) with a number-average mol. wt. of 85-20000 and a polar group and the composition also contains 5-75 vol% lower alkanol(s). An independent claim is also included for a method for improving the efficacy of detergent or valve seat wear-inhibitor additives in low-sulfur fuel by adding a lower alcohol.
