The present invention pertains to the field of rocketry and more precisely to liquid-propellant rocket engines and to rocket power units. This invention essentially relates to a method for increasing the specific impulse in a liquid-propellant rocket engine by using oxygen as well as a hydrocarbon fuel consisting of dicyclobutyl (C H ). The dicyclobutyl provides for a substantial increase in the specific impulse of the liquid-propellant rocket engine when compared with kerosene. This invention also relates to a power unit for a rocket that has tanks for liquid oxygen and for the hydrocarbon fuel. Since the fuel tank is filled with dicyclobutyl (C H ), it is thus possible to increase the thrust, the specific impulse, as well as the in-flight operation duration of the engine, and to reduce the weight of the tanks without any substantial change in the circuits of the liquid-propellant rocket engine and of the rocket power unit.

Method for inhibiting the polymerization of vinyl aromatics

In the production of styrene, spontaneous polymerization of styrene monomer causes reduced efficiency and as such it is desirable to prevent the formation of polymer by the addition of inhibitors. A known inhibiting composition is 3,5-di-tert-butyl-4-hydroxy-N,N-dimethylbenzyl amine and carboxylic acid, or an anhydride of said carboxylic acid which is added to a styrene-containing mixture. However large quantities are required and often portions of the inhibiting composition are not utilized resulting in nonproductive loss. The efficiency of the specific inhibitor can be improved by supplying air simultaneously with the inhibiting composition in a weight ratio of 3,5-di-tert-butyl-4-hydroxy-N,N-dimethylbenzyl amine to carboxylic acid to air, said ratio being 1:1-0.05:0.05-15.
