Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0020] see figure 1 As shown, the embodiment of the present invention provides a cooling mechanism for organic reactions, including a tube body 1, a product channel 2 is arranged inside the tube body 1, the product channel 2 includes a high temperature channel 3 and a low temperature channel 4, and the high temperature channel 3 is The spiral pipe, the low-temperature passage 4 is a straight pipe, and the length ratio of the high-temperature passage 3 to the low-temperature passage 4 is 1:0.5-2.
[0021] Since the high-temperature gas passes through the high-temperature pipeline 3, there will be no product retention, resulting in the situation that the high-temperature pipeline 3 is difficult to clean, and the spiral pipeline can increase the direct contact area and contact time between the high-temperature gas and the air condensing part 7, e...

The invention discloses a cooling mechanism for an organic reaction and relates to the field of cooling pipes. The cooling mechanism comprises a pipe body. A product channel is arranged inside the pipe body; the product channel comprises a high temperature channel and a low temperature channel; the high temperature channel is a spiral pipeline, the low temperature channel is a straight pipeline, and the length ratio of the high temperature channel to the low temperature channel is 1: 0.5-2; Cooling space is located between the product channel and the pipe wall of the pipe body. The part, corresponding to the high temperature channel, of the cooling space is an air condensing part, and the part, corresponding to the low temperature channel, of the cooling space is a water condensing part. The air condensing part comprises an inner pipe and an outer pipe. The high temperature channel is sleeved with the inner pipe, and the inner pipe is sleeved with the outer pipe. An air inlet and an air outlet are formed in the bottom of the inner pipe. A condensed water inlet is formed in the bottom of the outer pipe, and the outer pipe and the water condensing part communicate through the condensed water outlet and used for guiding water after being used for cooling air into the water condensing part. A water outlet is formed in the upper portion of the water condensing part. According to the cooling mechanism, a cooled product can be obtained rapidly, and experimental time is shortened.
Description
technical field [0001] The invention relates to the field of condensation pipes, in particular to a cooling mechanism for organic reactions. Background technique [0002] When performing an organic chemical reaction, it is usually necessary to purify and collect the product obtained by the reaction by distillation or fractionation. When the reaction temperature of the product is high and the temperature of the crude product obtained is high, it can only be carried out by using an air condenser. Condensation, to avoid the explosion of the condenser due to excessive temperature difference; when the temperature of the crude product is low, it can be cooled by water cooling. [0003] However, the contact surface between the air condenser and the substance to be cooled is relatively small, and the air tends to stay in the condenser pipe and is difficult to discharge, resulting in poor cooling effect, unable to quickly obtain products, and prolonging the experiment time.
