Pressure drop jacket vessels

This design provides high velocity and turbulence within the jacket. This in turn will result in an unusually high film coefficient. The half pipe coil is recommended for high temperature and all liquid applications. It is better than conventional jackets because the pressure drop can be carefully controlled and calculated. It is not however practical for small vessels, less than 500 gallons. Because there are no limitations to the number of inlet and outlet connections, this type of jacketing can be divided into multiple zones for maximum flexibility and efficiency.

Method B. Irradiation with a mercury arc lamp. Use the 100 watt medium-pressure mercury arc lamp with the Pyrex outer and inner jackets (Section 2.17.5, p. Ill) and a reaction vessel of approximately 110ml capacity (Fig. 2.67(f)). Make up a solution of 10 g (0.055 mol) of benzophenone in about 110 ml of propan-2-ol containing one drop of glacial acetic acid as described... 

In a microwave reaction vessel containing a magnetic stir bar, place 1.6 mL (14.7 mmol) of isopentyl alcohol, 3.0 mL (52.4 mmol) of glacial acetic add, 8 drops (Pasteur pipet) of concentrated sulfuric acid, and approximately 200 mg of silica beads. Immediately cap the vessel with the microwave pressure cap and adjust the tightness to the manufacturer-specified level. Place the sealed vessel into its outer protective jacket.
