Gaseous oxidant oxygen, be then shut off gaseous oxidant entrance 13；Pass through agitator motor cooling water inlet 7 and blender electricity
Machine cooling water outlet 8 is passed through cooling water to stirring motor 6, opens stirring motor 6 and stirring rod 23 and agitating paddle 24 is driven to rotate；It is logical
It crosses temperature-measuring port 15 and temperature thermocouple is inserted into thermometric blind pipe 21；Start heating mantle 25, heats reaction kettle 19；It is blind by insertion thermometric
The thermocouple of pipe 21 and the temperature and pressure being connected in the pressure gauge detection reaction kettle 19 of pressure tap 16；When temperature is higher than
374.2 DEG C, when pressure is higher than 22.1MPa, after the reaction time for keeping design, stops heating mantle 25 and heat；It is sliding to adjust muff
Block 4 reduces the height of muff 26, is exposed to heating mantle 25 in air, passes through 11 He of reaction kettle recirculated cooling water water inlet pipe road
Reaction kettle recirculated cooling water outlet pipeline 12 is passed through cooling water to reaction kettle circulating cooling water coil 22, reduces in reaction kettle 19
Temperature；When the temperature in reaction kettle 19 is reduced to room temperature, stop cold to agitator motor cooling water inlet 7 and reaction kettle circulation
But water inlet 11 injects cooling water, and cracking pressure bleed outlet 17 discharges the pressure in reaction kettle 19 to normal pressure；Disassembly is fixed on anti-
The bolt for answering kettle cover bolt hole 10 and reaction kettle bolt hole 20 reduces by 19 height of reaction kettle by adjusting reaction kettle sliding block 4；It takes out
Reaction product in reaction kettle 19 and the metal agitating paddle 24 being fixed on stirring rod 23, the analysis for carrying out next step are examined
It surveys；Clean reaction kettle 19 and its internal part.
