Reactor for organic synthesis

Abstract

The invention discloses a reactor for organic synthesis, and relates to the field of organic reaction. The reactor comprises a bottle body, wherein a plurality of inserting openings are formed in the bottle body; a heating jacket is arranged outside the bottle body and comprises an outer jacket part and a heated part; the outer jacket part coats at least 2 / 3 area of the outside of the bottle body; the heated part is fixed at the bottom of the outer jacket part; the heated part is used for being in contact with a heat source and transferring heat to the outer jacket part; a heat conductor is arranged between the outer jacket part and the bottle body and the thickness of the heat conductor is 4-8mm; the thickness of the outer jacket part is sequentially increased from bottom to top; the thermal conductivity of the heating jacket is greater than 50W / M*K; and the thermal conductivity of the heat conductor is greater than 30W / M*K. The reactor disclosed by the invention is relatively small in cleaning difficulty and the experiment cost can be reduced.

Description

technical field [0001] The invention relates to the field of organic reactions, in particular to a reaction kettle for organic synthesis. Background technique [0002] When carrying out simple organic reactions in the laboratory, multi-necked flasks are usually used as reaction kettles. According to the temperature required for the reaction, the reaction kettles are placed in water baths, oil baths or sand baths, and then the condensers are inserted into different bottlenecks. Device, thermometer, constant pressure dropping funnel, etc., and finally add the reaction medicine to carry out the corresponding reaction. [0003] Since the oil bath usually uses silicone oil, it is difficult to clean after it adheres to the outside of the reactor, and the silicone oil is easy to splash into the bottle during the cleaning process, causing extensive pollution, making cleaning difficult, time-consuming, and waste of silicone oil , to increase the cost of the experiment; when using a ...

Problems solved by technology

[0003] Since the oil bath usually uses silicone oil, it is difficult to clean after it adheres to the outside of the reactor, and the silicone oil is easy to splash into the bottle during the cleaning process, causing extensive pollution, making cleaning difficult, time-consuming, and waste of silicone oil , to increase the cost of the experiment; when using a sand bath, sand is usually placed in the electric heating jacket. Since the diameter of the electric heating jacket is usually small, the contact area with the reactor is small, and the experimenter is prone to uneven thickness when laying the sand. The reactor is heated unevenly, which makes the heat distribution in the reactor uneven, which in turn affects the reaction progress in different areas, resulting in poor purity of the reaction product
