The temperature of the jacket is measured by a temperature sensor attached to the jacket, so that the data is more accurate.
The principle of the reaction heat calculation of the reaction kettle is a heat flow principle:
(Qr+Qc+Qs)＝(Qa+Qi)+(Qf+Qd+Ql+Qre)
Qr: rate of heat generated by the chemical reaction, W; qcHeating rod calibration power, W; qsHeat, W, from the stirrer; qaHeat of storage of the reaction mass, W; qiHeat stored in the kettle inner parts, W; qfHeat flow through the jacket reactor wall, W; qdThe heat, W, brought in by the dropping material; qlHeat loss of the reaction kettle, W; qreHeat lost from the reflux condenser, W. (Note: in the reaction heat test, the heat flow, heat release rate and power were the same, so the heat flow rate, heat quantity, power unit was unified as power W in example 1).
Wherein: qd＝dmd/dt*Cpd*(Tr-Td)；
Qf＝UA*(Tr-Tj)；
md: mass of the dropping charge, g; cpd: specific heat capacity of dropwise addition, J.g-1·K-1；Tr: the process temperature of the reaction, K; t isd: the temperature of the dropping material, K; t isj: the temperature of the jacket, K, is measured by temperature sensors at the inlet and outlet of the jacket; UA: calibration factor, W.K-1。
Determination of UA: UA ═ Q-c·dt/∫ΔT·dt
The sample was heated with a heater given a known power and the jacket temperature was reduced to maintain the sample process temperature, and "UA" was calculated from the sample to jacket temperature difference at thermal equilibrium.
The calculation of the reaction heat flow in the reaction process when the difference between the dropping material and the process temperature is not large can be processed approximately: qr＝Qf＝UA* (Tr-Tj)。
From the measured real-time heat flow curve, the heat released during the reaction H, H ═ ═ q ═ dQ/dt · dt can be calculated.
[ example 2 ]
The reaction calorimeter was used to test the heat of reaction of the reduction of the cis-acid chloride according to the conditions and procedures of example 1: oxygen is replaced in the reaction kettle, 200g of absolute ethyl alcohol and 30g of zinc powder are added through a bottom material feeder 4, and the process temperature is 60 ℃. Keeping the temperature for half an hour after the temperature of the reaction kettle rises to 60 ℃, then starting a heating rod to correct the power, and measuring the pre-correction UA1. Then a feeding pump is used for dripping 400g of the maleic chloride solution through a dripping port 18, and after the dripping is finished, the reaction is carried out for a period of time under the process temperature. Then starting the heating rod to correct the power, and measuring the post-correction UA2。
After the reduction reaction is finished, processing experimental test data to obtain pre-correction UA1Post-correction UA2And a heat flow curve, wherein the heat of reaction of the reduction reaction of the cis-acid chloride is 120kJ by integrating the heat flow curve with time.
[ example 3 ]
The reaction calorimeter was used to test the heat of chemical reaction of furfural phosgenation according to the conditions and procedures of example 1: 200g of dichloroethane, 100g of N, N-dimethylformamide and 110g of methylfuran are introduced via a base feeder 4 at a process temperature of 15 ℃. Keeping the temperature for half an hour after the temperature of the reaction kettle is reduced to 15 ℃, then starting a heating rod to correct the power, and measuring the pre-correction UA1. Then 570g of triphosgene solution is dripped through the dripping port 18 by using a feeding pump, and after the dripping is finished, the reaction is carried out for a period of time under the process temperature. Then starting the heating rod to correct the power, and measuring the post-correction UA2。
After the reaction is finished, processing experimental test data to obtain pre-correction UA1Post-correction UA2And a heat flow curve, wherein the chemical reaction heat of the furfural phosgenation reaction is 225kJ by integrating the heat flow curve with time.
