【Deep Coating Society Industry Analysis】N-vinylcarbazole demand is stable The market concentration is high from 2022 to 2026

N-vinylcarbazole has the molecular formula C14H11N and is a white-like crystalline powder
in appearance.
N-vinylcarbazole is an important nitrogen-containing aromatic heterocyclic compound with special photoelectric properties, which is in line with the performance of organic photoelectric functional materials, has strong intramolecular electron transfer function, and its thermal stability is also relatively good
.

At present, the methods for synthesizing N-vinylcarbazole are mainly as follows: (1) carbazole potassium salt and vinyl chloride are directly reacted at high temperature to obtain N-vinylcarbazole; Carbazole and 1,2-dichloroethane under alkaline conditions, Mr.
9-(β-chloroethyl) carbazole, and then dehydrochlorinated to obtain N-vinylcarbazole; carbazole and ethylene oxide react under alkaline conditions to obtain 9-(β-hydroxyethyl)carbazole, which loses water in potassium hydroxide ethanol solution to obtain N-vinylcarbazole; Carbazole and acetylene react directly to synthesize N-vinylcarbazole and the like
.

N-vinylcarbazole has two major application fields: one is the field of liquid crystal materials, and the other is the field of pharmaceutical intermediates, of which the application purity requirements in the field of liquid crystal materials are higher
.
However, due to the low degree of market development, the low awareness of the product by downstream users, the high price and other factors, the demand for N-vinylcarbazole in the above two application fields is not large
.
According to the "2022-2026 China N-vinylcarbazole Industry Market Monitoring and Future Development Prospect Research Report" released by Xinsijie, the growth rate of China's N-vinylcarbazole demand will remain between
3% and 5% from 2017 to 2021.
In recent years, with the increase of the difficulty of domestic market development, enterprises have gradually strengthened the development of foreign markets, and Japan and South Korea are the most important export areas
of N-vinylcarbazole in China.

Due to the small demand and slow growth, in recent years, China's N-vinylcarbazole industry investment enthusiasm is not high, and the N-vinylcarbazole synthesis process is complex, the technical entry barriers are high, and investors are also
blocked.
In addition, N-vinylcarbazole is a hazardous chemical, and the production process will produce pollution, China's stricter supervision of hazardous chemicals and the improvement of environmental protection requirements, but also make the development of the industry more difficult, corporate profitability declined
.
Therefore, the number of production enterprises in China's N-vinylcarbazole industry has maintained the original level
.
At present, the main manufacturers of N-vinylcarbazole in China include Zibo Aote Fine Chemical Factory, Juye Modern Fine Chemical Co.
, Ltd.
, Changzhou Nimo Chemical Co.
, Ltd.
, etc
.

Xinsijie industry analysts said that although the future of China's N-vinylcarbazole market demand will still show a growth trend, but the overall market size is still limited, and the application of N-vinylcarbazole in Japan and South Korea is more mature, and China encourages enterprises to "go global", therefore, N-vinylcarbazole enterprises can increase the international market development
