Изобретение относитс к области химических ihpoueccoB, а именно к управлению работой химических реакторов, и может быть использовано в химической, нефтеперерабатьюающей и фармацевтической промышленности.The invention relates to the field of chemical ipoueccoB, namely to the management of the operation of chemical reactors, and can be used in the chemical, petroleum refining and pharmaceutical industries.

Известен способ управлени работой реакторов полунепрерьшного действи путем изменени подачи реагента в зависимости от отношени величины температурного перепада на стенке реактора к разности температур хладагента на входе в рубашку и выходе из нее 1.A known method of controlling the operation of semi-continuous reactors is by varying the supply of reagent depending on the ratio of the temperature difference on the reactor wall to the temperature difference of the refrigerant at the inlet and outlet of the jacket 1.

Наиболее близким по технической сущности к изобретению вл етс способ управлени .работой химических реакторов путем изменени подачи компонента в зависимости от температуры реакционной массы с коррекцией по величине отношени производных количества тепла , отводимого из реактора, и количества тепла , вьодел ющегос в реакторе, к температуре и подачи хладагента в рубашку {2.The closest in technical essence to the invention is the method of controlling the operation of chemical reactors by changing the component feed depending on the temperature of the reaction mass with a correction in the ratio of the derivative of the amount of heat removed from the reactor and the amount of heat generated in the reactor to supply of refrigerant to shirt {2.

Недостатком известного способа вл ет;с . сложность точного определени количества подводимого тепла и теплоты реакции, что приводит к малой надежности управлени процессом в целом.The disadvantage of this method is; c. the difficulty of accurately determining the amount of heat input and reaction heat, which leads to low reliability of control of the process as a whole.

Целью изобретени вл етс увеличение выхода продукта и повышение надежности системы управлени .The aim of the invention is to increase the product yield and increase the reliability of the control system.

Указанна цель достигаетс тем, что подачу нитруемою компонента измен ют в зависимости от разности сигнала расхода нитрующего компонента и заданной величинь отношени расходов нитрируюшего и нитрируемогокомпонентов, а подачу хладагента в рубашку - в зависимости от величины расхода нитруемого компонен- ,This goal is achieved by the fact that the supply of the nitrate component is changed depending on the difference between the flow rate signal of the nitrating component and the set value of the ratio of the flow rates of the nitrating and nitrated components, and the coolant flow into the jacket, depending on the magnitude of the nitrate component flow,
