Abstract
Способ отгонки этилацетата из сферических пороховых элементов, находящихся в дисперсионной среде в реакторе, включающий подачу теплоносителя в рубашку реактора и кипение смеси в реакторе в развитом пузырьковом режиме кипения, отличающийся тем, что пары этилацетата из реактора поступают в верхнюю часть в трубное пространство вертикально установленного холодильника за счет разности парциальных давлений между реактором и холодильником, создаваемым путем подачи охлаждающей воды в турбулентном режиме в нижнюю часть холодильника в межтрубное пространство, при этом сконденсированные пары этилацетата поступают из холодильника в сборник этилацетата, который связан с атмосферой через обратный холодильник, при этом температура воды, подаваемой в холодильник и выходящей из холодильника, не должна превышать 1…2°С, а поверхность конденсации холодильника должна превышать поверхность испарения этилацетата в реакторе в 4…5 раз.The method of distillation of ethyl acetate from spherical powder elements located in a dispersion medium in the reactor, comprising supplying a coolant to the jacket of the reactor and boiling the mixture in the reactor in a developed bubble mode of boiling, characterized in that the ethyl acetate vapor from the reactor enters the upper part into the pipe space of a vertically installed refrigerator due to the difference in partial pressures between the reactor and the refrigerator created by supplying cooling water in a turbulent mode to the lower part of the refrigerator in the interior free space, while condensed ethyl acetate vapors come from the refrigerator to the ethyl acetate collector, which is connected to the atmosphere through the reflux condenser, while the temperature of the water supplied to the refrigerator and leaving the refrigerator should not exceed 1 ... 2 ° C, and the condensation surface of the refrigerator should exceed the evaporation surface of ethyl acetate in the reactor by 4 ... 5 times.
