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.

Process for the performance of chemical reaction with atomic hydrogen

A method of preparing compounds having at least one olefinic double bond, ich method comprises irradiating the corresponding saturated halogenated compound in gaseous form, with pulsed coherent light or incoherent light, adjusting the wavelength of the irradiated light and the pressure and temperature conditions so that a captured cross-section of 10.sup.-15 to 10.sup.-25 cm.sup.2 per molecule results, to split off hydrogen halide from said corresponding saturated compound yielding said olefinic compound.
