[Title <strong>of</strong> the Invention]<br />

A process <strong>of</strong> removal <strong>of</strong> the heat <strong>of</strong> exothermal reaction<br />

[Claims]<br />

1. A process <strong>of</strong> removal <strong>of</strong> reaction heat from the liquid phase <strong>of</strong> nitration reaction <strong>of</strong> aromatic<br />

compound, which comprises:<br />

(a) placing the raw material mixture consisting <strong>of</strong> an aromatic compound, nitration reagent<br />

and a solvent as well as the starting mixture and immiscible, inactivated fluid into the<br />

reaction vessel and mix until homogeneous,<br />

(b) separating the emulsion from into the phase that contains the reaction product and the<br />

heated immiscible, inactivated phase,<br />

(c) cooling the said immiscible, inactivated liquid phase, and<br />

(d) Reintroducing the immiscible inactivated liquid phase into the reaction vessel.<br />

2. Equipment <strong>for</strong> removal <strong>of</strong> exothermal reaction which comprises:<br />

(a) A reaction vessel (3) having a supply channel (1, 2) <strong>for</strong> starting material and solvent to<br />

mix raw material mixture and immiscible, inactivated liquid phase until homogeneous.<br />

(b) a separator vessel (4) to separate the reaction product and immiscible, inactive phase,<br />

which is connected to the reaction vessel (3), and<br />

(c) Heat exchange vessel (5) that removes heat and re-cycles the immiscible, inactive<br />

phase that is connected to the separator (4) and reaction (3) vessels.<br />

[Excerpt from Detail Description <strong>of</strong> the Invention and Drawing]<br />

This invention concerns the process <strong>of</strong> removal <strong>of</strong> reaction heat from the liquid phase <strong>of</strong><br />

nitration reaction <strong>of</strong> aromatic compound and equipment which continuously removes the<br />

reaction heat <strong>of</strong> exothermal reaction.<br />

[Explanation]<br />

Though the equipment <strong>of</strong> the related invention (Claim 2) could be applied to processes<br />

other than the process <strong>of</strong> the specified invention (Claim 1), the equipment is suited to carrying<br />

out the process <strong>of</strong> the specified invention.<br />

The equipment in the related invention falls under the category <strong>of</strong> equipment directly<br />

used in working the specified invention.<br />
