Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a reactor with gas-liquid separation function. Background Art

[0002] Isoxazoline, also known as dihydroisoxazole, theoretically has three isomers: I, II, and III. In practice, only I exists. It is insoluble in acid and alkali, and does not revert to isoxazole after dehydrogenation. The preparation method is as follows: (1) Hydroxylamine is used to act on α, β-unsaturated ketone or β-haloketone; (2) Its derivatives 3-methylisoxazoline can be synthesized from methyl chloroethyl ketone, and 3-phenylisoxazoline can be synthesized from β-chloroacetone. They are used as raw materials for organic synthesis. Dihydroisoxazole is a compound with high biological activity and potential physiological and pharmacological activity, and has attracted widespread attention.

[0003] At present, the preparation of dihydroisoxazole needs to be carried out in a reactor, but the reactor is generally inconvenient for gas-liquid separation. The gas produced by the reaction is directly discharged through the exhaust port, and the materials mixed in the gas are directly discharged outdoors, which not only pollutes the external environment but also easily causes waste of raw materials and increases production costs. Therefore, improvement is urgently needed. Utility Model Content
