Embodiment Construction

[0019] like figure 1 As shown, the special reactor for the directional synthesis of p-chlorotoluene of the present invention includes a reactor body 1, and the upper part of the reactor body 1 is provided with a first hollow inlet plate 2, a hollow liquid inlet plate 3, and a first hollow inlet plate 3. There are several nozzles 4 on the gas plate, such as figure 2 As shown, it consists of an inner tube 41, an outer shell 42 and a nozzle 43. The inner tube is connected to the first hollow inlet plate 1, and the outer shell is connected to the hollow liquid inlet plate 2; the inner space of the inner tube is connected to the first hollow inlet plate 2. The air inlet space of the air plate; the inner space of the shell is connected to the liquid inlet space of the hollow liquid inlet plate; the lowermost end of the inner pipe is closed. There are several small holes all over the inner tube, the diameter of the small holes is less than 5mm, and the distribution of the small hol...

Abstract

The invention discloses a special reactor for oriented synthesis of p-chlorotoluene. The special reactor comprises a reactor body 1, wherein a first hollow air inflow board 2 and a hollow liquid inflow board 3 are arranged at the upper part of the reactor body 1; a plurality of nozzles 4 are arranged on the first hollow air inflow board; each nozzle consists of an inner tube, a housing and a spray nozzle; the inner tubes are connected with the first hollow air inflow board 1; the housings are connected with the hollow liquid inflow board 2; a second hollow air inflow board 5 is arranged at the lower part of the reactor body; a plurality of injection orifices are formed in the second hollow air inflow board; the nozzles are arranged opposite to the jetting directions of the injection orifices.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, in particular to a special reactor for directional synthesis of p-chlorotoluene. Background technique [0002] Both p-chlorotoluene and o-chlorotoluene are very important fine organic chemical raw materials. In recent years, the production of a variety of new pharmaceuticals, pesticides, dyes and other intermediates have used them as starting materials, and these intermediates have shown very bright development prospects. , the domestic and foreign markets are unanimously optimistic. The huge development space in the downstream market stimulates and promotes the production and development of chlorotoluene. There are two main methods for the industrial synthesis of chlorotoluene. The most commonly used method is the direct chlorination method using toluene as a raw material. Toluene chlorination mainly produces three isomers: o-chlorotoluene, m-chlorotoluene and p-chlorotoluene, among...
