        Experimental plant of the Academy of Science of U.S.S.R. constructed an autoclave for syntheses (NH₃, MeOH, etc.), cracking, hydrogenation, etc.  The autoclave consists of a reaction chamber within an electric oven.  The pressures on both sides of the walls of the reactor are regulated by passing out the excess gases through valves in the reactor and the oven.  With a 500-atm. outside pressure for the reactor, inner working pressures of 800, 1,000, and 1,200-atm., with corresponding working temperatures of 800°, 700°, and 600°, respectively, are possible.
