Ferrocene dicarboxylic acid diesters have the general formula (I), in which X stands for an oligoethylene glycol radical with 2 to 20 ethoxyl units and/or an &agr;,&ohgr;-alkyldiol radical with 2 to 18 C atoms. Also disclosed are processes for preparing the same, their use, solid composite propellants containing the disclosed ferrocene dicarboxylic acid diesters and processes for preparing the same.

Metal oxide powders comprised of Cr(III) oxide, Ti(IV) oxide, V(V) oxide, or mixtures of these, or metal mixed oxides comprised of Cr(III) oxide and Ti(IV) oxide and V(V) oxide, or their mixtures. They have BET surfaces of 5-50m.sup.2 /g and mean particle diameters of 25-350 nm and are useful to increase conversion and selectivity in the manufacture of mono-olefins by catalytic dehydrogenation of saturated hydrocarbons. The metal oxide powders are produced from mixtures of the vaporized metal compounds chromyl chloride, titanium tetrachloride, and vanadyl chloride, in the presence of certain gases by laser pyrolysis.

A process for dehydrogenating saturated or unsaturated hydrocarbons wherein the flow direction of the oxygen-containing gas, employed for removing coke deposits on the catalyst surface, is opposite to that for the hydrocarbon feed undergoing dehydrogenation.

Method for dehydrogenating hydrocarbons

Atomic hydrogen for chemical reaction is produced in relatively high concentrations by the combustion of molecular hydrogen with a substoichiometric quantity of oxygen. The chemical reactant is supplied at the point of the development of the atomic hydrogen. Combustion is effected at pressures between 10 mbar and 1.5 bar, with a mole ratio of molecular hydrogen to molecular oxygen of 2.3 to 5.0.
