摘要： The present invention provides a process for quenching a gaseous reaction mixture during the phosgenation of diamines in the gas phase to produce diisocyanates. The gaseous reaction mixture contains at least a diisocyanate, phosgene and hydrogen chloride. The quenching liquid is injected into the gas mixture continuously flowing out of a cylindrical reaction zone into the downstream cylindrical quenching zone with the aid of at least two spray nozzles which are arranged at the entrance to the quenching zone at equal distances along the circumference of the quenching zone.

摘要： In a method for improving heat transfer in a heat exchanger, in which a heating medium passes through heat exchange elements 1,8 which transfer their heat to a liquid with which they are in contact and which is located in the jacket region 3 of the heat exchanger, the liquid between the heat exchange elements in the jacket region 3 is heated locally to such a high temperature by means of additional heating elements 2,9 that nucleate boiling occurs in the liquid on the surface of these additional heating elements 2,9 and the resulting vapour bubbles ascend between the normal heating exchange elements 1,8 in the jacket region 3. For this purpose an evaporative condenser containing vertically superimposed heat exchange elements 1,8 extending in a horizontal direction and a shell enclosing the jacket region 3 of the heat exchange elements 1,8 is provided, in which additional heating elements 2,9 connected to a heating medium circuit which is separate from the heat exchange elements 1,8 are arranged beneath the heat exchange elements 1,8, preferably in the bottom third of the vertical arrangement.
