Embodiment Construction

[0038] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below in conjunction with examples.

[0039] As mentioned in the background technology, most of the existing n-butyllithium reactions are produced in batches and single-pots, which often require one-time transfer or long-term dropwise addition of a large amount of n-butyllithium, resulting in high process risks. In order to reduce the risk of this similar reaction, in a typical implementation of the present application, a continuous tank reaction device 01 is provided, such as figure 1 and image 3 As shown, the continuous tank reaction device 01 includes N continuous reactors 10 arranged in series in sequence, each continuous reactor 10 includes a body 11, and the body 11 has a reaction chamber 111, a feed port 112, an overflow port 113 and an outlet. A fe...

Abstract

The invention provides a continuous tank reactor and a continuous tank reaction system with n-butyllithium participating in production. The continuous tank reactor comprises N continuous reaction kettles successively connected in series. Each continuous reaction kettle comprises a body, which has a reaction chamber, a feed inlet, an overflow mouth and a discharge port. N is a natural number whichis greater than or equal to 2. The overflow mouth of the N-1 continuous reaction kettle is communicated with the feed inlet of the N continuous reaction kettle. The continuous tank reactor issuitable for chemical reactions with chemical substances having active chemical properties such as n-butyllithium, etc. participating in the reactions. In actual production, an appropriate number of the continuous reaction kettles can be selected according to the need of reacting dose for a continuous reaction. Thus, lots of reaction raw materials transferred at a time or dropwise added for a longtime in single-kettle batch production are reduced, reaction operational risk is reduced, and safety and reaction efficiency are enhanced.

Description

technical field [0001] The invention relates to the field of organic synthesis, in particular to a continuous tank reaction device and a continuous tank reaction system in which n-butyllithium participates in production. Background technique [0002] As a strong base, n-butyllithium can be used as a lithiation reagent for substrates containing active hydrogen, and can also be used in lithium-halogen exchange reactions or lithium-metal transfer metallation reactions, and is widely used in organic synthetic chemistry and pharmaceutical industries. In addition, n-butyllithium can also be used as a polymerization catalyst and an alkylating agent to initiate anionic polymerization of conjugated dienes to prepare low-cis polybutadiene rubber, isoprene rubber, thermoplastic rubber, thermosetting resin and paint etc. In general, n-butyllithium is an important class of chemical reagents, widely used in organic synthesis industry and polymer industry. [0003] However, the nature of...
