Description

Известные способы определени  кинетики поглощени  кислорода при жидкофазном окислении нефтепродуктов и других веществ имеют тот недостаток, что при отсчетах поглощенного кислорода не исключаютс  искажени , обусловленные изменени ми во врем  опытов величины атмосферного давлени .The known methods for determining the kinetics of oxygen absorption during the liquid-phase oxidation of petroleum products and other substances have the disadvantage that in the readings of absorbed oxygen, distortions due to changes in atmospheric pressure during experiments are not excluded.

Описываемый способ отличаетс  тем, что определение иоглощени  кислорода производ т при посто нном давлении с помощью включени  в схему установки манометрического индикатора давлени , ноказани  которого не завис т от величины атмосферного давлени .The described method is characterized in that the determination of oxygen absorption is carried out at a constant pressure by including in the installation scheme a gauge pressure indicator, but the reading of which does not depend on the magnitude of the atmospheric pressure.

Такой способ обеспечивает большую точность отсчетов ири проведении опытов.This method provides greater accuracy of the readings and experiments.

Принципиальна  схема установки дл  осуществлени  описываемого способа приведена ниже.A schematic diagram of the installation for implementing the described method is given below.

Установка состоит из реактора /, индикатора давлени  2, измерительной бюретки 3 и уравнительного сосуда 4.The installation consists of a reactor /, a pressure indicator 2, a measuring burette 3 and leveling vessel 4.

В индикатор давлени  заливаетс  жидкость (например, дибутилфталат ) с таким расчетом, чтобы жидкость в открытом конце трубки была на 8-10 см выще, чем в запа нном. После соединени  прибора с реактором / устанавливают уровни жидкости в индикаторе давлени  2 на одной высоте. При изменении внещнего давлени  или давлени  внутри системы уровни в индикаторе давлени  2 и в измерительной бюретке 3 соответственно смещаютс .A liquid (e.g. dibutyl phthalate) is poured into the pressure indicator so that the liquid at the open end of the tube is 8–10 cm higher than in the sealed one. After connecting the instrument to the reactor / set the liquid levels in the pressure indicator 2 at the same height. When the external pressure or pressure inside the system changes, the levels in pressure indicator 2 and in measuring burette 3 are shifted accordingly.

Дл  восстановлени  прежнего давлени  необходимо перемещать уравннтельный сосуд 4 пока уровни в индикаторе давлени  2 не расположатс  на одной черте.To restore the previous pressure, leveling vessel 4 must be moved until the levels in pressure indicator 2 are on the same line.

При этом, если смещение уровней произощло за счет изменени  внещнего давлени , то жидкость в измерительной бюретке 3 вернетс  на старую отметку, а если произощло поглощение кислорода, то она поднимаетс  на высоту, соответствующую количеству поглощенного кислорода при давлении и температуре системы.In this case, if the displacement of the levels was due to a change in the external pressure, the liquid in the measuring burette 3 would return to the old mark, and if oxygen absorption would occur, then it rises to a height corresponding to the amount of oxygen absorbed at the pressure and temperature of the system.

Предмет изобретени Subject invention

Споеоб лабораторного определени  кинетики жидкофазного окиелени  вещеетв путем последовательных отсчетов объемов поглош,енного кислорода в замкнутой системе, при давлении, поддерживаемом перемещением по, .вертикали уравнительного сосуда, отличающийс  тем. что, с целью повышени  точности отсчетов, в систему лабораторной установки включают индикатор давлени , разобщенный с наружной атмосферой, позвол ющий производить эти отсчеты при посто нном давлении.The laboratories determine the kinetics of liquid phase oxidation of substances by successive counts of volumes of absorbed oxygen in a closed system, at a pressure supported by moving along the leveling vessel, differing in that. that, in order to improve the accuracy of the readings, a pressure indicator separated from the outside atmosphere is included in the laboratory setup system, which allows these readings to be carried out under constant pressure.
