A system for producing, stabilizing, and concentrating tri-atomic hydrogen includes a source of liquid hydrogen in the form of para-hydrogen, a piping system through which the liquid hydrogen flows, an injection point for combining the liquid hydrogen in the form of para-hydrogen with third hydrogen atoms all with the same proton spin to form Hall with the same net magnetic orientation, and a continuous magnetic field for maintaining the magnetic orientation. The system further has a storage tank for storing concentrated liquid Hmolecules for use as a propellant.

Mobile mixtures of an oxirane compound and a labile hydrogen compound such as an acid, anhydride, imide or sulfonimide can be stored at long periods of time under ambient conditions in the presence of a latent chromium III chelate. At an elevated temperature, the catalyst is activated and rapidly converts the mixture into a more advanced state of cure.

This patent describes a method of catalyzing the reaction of organic polybasic acid anhydrides with at least one oxirane which comprises carrying out the reaction in the presence of an effective catalytic amount of a synergistic catalyst mixture comprising an active chromium III tricarboxylate salt having unoccupied coordination sites and any compound capable of polarizing the carboxylic acid anhydride to yield a reactive carboxylic acid moiety. Preferred compounds as the cocatalyst member include one or more members selected from the group consisting of the alkyl, aryl, aralkyl, and alkaryl tri-substituted compounds of the following types: quaternary ammonium hydroxides; quarternary phosphonium halides; arsines; amine oxides; sulfoxides; tertiary aminophenols; trihydrocarbon phosphine oxides; trihydrocarbon phosphines; tertiary amines, and combinations thereof, each alone or in combination with a phenol or other reactive promoter such as, carboxylic acids and alcohols; and compounds containing two or more co-catalytic functional groups in the same molecule such as alkyl phosphoramides, alone or in combination with any and all of (1) any of the members, (2) phenols or other reactive promoters. Also the invention pertains to a novel class of mixed catalysts which act synergistically for promoting the reaction of oxirane oxygen groups with curing (crosslinking) or chain extension agents.
