N-bromosuccinimide has a wide range of applications and great development value

N-bromosuccinimide, also known as N-bromosuccinimide, abbreviated as NBS in English, is a five-membered cyclic dicarboximide compound with a bromine substituent on the nitrogen atom. The chemical formula is C4H4BrNO2. Appearance is white to milky white crystalline, has a bromine-like odor and is toxic. N-bromosuccinimide is insoluble in water, insoluble in ether, benzene, chloroform, carbon tetrachloride, slightly soluble in acetic acid, soluble in acetone, ethyl acetate, acetic anhydride, tetrahydrofuran, N,N -Dimethylformamide, dimethyl sulfoxide, etc. N-bromosuccinimide is a commonly used chemical raw material.

According to the “2022-2026 N-bromosuccinimide Industry In-depth Market Research and Investment Strategy Suggestions Report” released by the Industrial Research Center shows that N-bromosuccinimide is a brominating agent with excellent performance and can be used in chemical, pharmaceutical, pesticide and other industries. It is used in the bromination reaction of allyl and benzyl compounds, and olefins. , negative ion bromination reaction of alkynes, electrophilic bromination reaction of ketones, aromatic compounds or heterocyclic compounds, etc.; can be used as a catalyst, oxidant; can also be used as bromination reagent, used to identify primary, secondary and tertiary alcohols, and determine drugs. preparations, etc.; it can also be used as a preservative, preservative, antifungal agent, etc. for vegetables and fruits. N-bromosuccinimide can be used in a wide range of applications and has great development value.

The preparation process of N-bromosuccinimide mainly includes: using succinimide as raw material, adding sodium hydroxide solution, bromine, and carbon tetrachloride for vigorous stirring to react, filtering, washing, and drying to obtain; Diacid and ammonia are used as raw materials, which are first reacted to form succinimide, and then brominated and refined to obtain it; using succinimide and sodium bromite as raw materials, hydrobromic acid is added for reaction.

Succinimide is an important raw material for the preparation of N-bromosuccinimide. Succinimide can be used in organic synthesis, pharmaceuticals, electroplating, chemical analysis, etc. Organic synthesis is its important application market, and N-bromosuccinimide is its important downstream product. At present, my country has the mass production capacity of succinimide. Against the backdrop of increasing environmental protection requirements, my country’s succinimide industry continues to improve production equipment and production processes, and product quality continues to improve. This is my country’s N-bromobutyl A good foundation has been laid for the development of the imide industry.

Since 2020, my country’s N-bromosuccinimide production capacity is still expanding. In 2020, the succinimide relocation and expansion project of Huzhou Yinrui New Materials Co., Ltd. has entered the environmental assessment stage. It plans to improve the succinimide production equipment and production technology, and expand the N-bromosuccinimide capacity by 200 tons/year. production capacity. In the same year, Shandong Hexin Chemical Technology Co., Ltd.’s 500 tons/year N-bromosuccinimide project was approved.

Industry analysts said that from an upstream perspective, my country has mass production capabilities for the raw material succinimide, and the production process and products The quality is still improving; from the downstream perspective, N-bromosuccinimide has a wide range of applications and has great development value; from the midstream perspective, my country’s N-bromosuccinimide production capacity is still expanding. Overall, the N-bromosuccinimide industry has good development prospects.
