| titleOfInvention | But 2-chlorine nicotinic acid is synthetic with control by temperature change reation kettle |
| abstract | The utility model relates to a temperature-controllable reaction kettle for synthesizing 2-chloronicotinic acid, belonging to the technical field of synthesis of 2-chloronicotinic acid. When the inside temperature of reation kettle body risees, the inside mercury of mercury column is heated the inflation, when mercury and first electric wire contact, the mercury column this moment, first electric wire, the second electric wire, form closed circuit between positive reverse rotation water pump and the external automatically controlled cabinet, automatically controlled cabinet can control positive reverse rotation water pump and take out the inside water of water tank and take out to the pivot pipe and fill pivot pipe and agitator pipe through the connecting pipe this moment, thereby cool down the inside of reation kettle body, and the control cabinet can control positive reverse rotation water pump reversal, can reciprocate like this precipitation from the inside input of pivot pipe and agitator pipe and take out from, can be with hydrologic cycle like this, make things convenient for the cooling of water, thereby better cooling, the effect of automatic temperature control has been reached from this. |
