Tape-wound vessels

Different types of forgings and tape-wound vessels for use as reactors for commercial operations, along witii heat exchangers, t3i>es of closures, valves, and instrumentation are described in the literature. ... 

To use the bomb, the vessel A is set in an upright position and charged with reactants and solvent B is then pushed home into A with the valve F open and the securing collar D is screwed down hand-tight.t The vessel is evacuated with a vacuum pump attached to the nozzle of F, the valve is closed and the vacuum line removed. The bomb is then positioned behind adequate safety shielding, preferably in an isolated position, and heated in an oil bath or preferably by an electrical heating tape wound around the barrel A. 

The apparatus shown in Fig. 2 has a 500-mL reaction vessel, which is coimected to a 50-mL reservoir for liquid /BP via a stopcock and a standard-taper joint, t The coimecting tubing between the reaction vessel and the mercury in the manometer must be wrapped with commercial heating tape or wound carefully with heating wire. The temperature of this section, which should be as short and of as small bore as feasible, is controlled with a variable-voltage power supply. It is not necessaiy to control this temperature accurately, but it should be close to the bath temperature (say, within 20°C) and must be above the boiling point of acetone (56°C).
