PROCESS FOR PRODUCING ANILINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18574795 titled 'PROCESS FOR PRODUCING ANILINE
The invention described in the abstract is a process for producing aniline through the catalytic hydrogenation of nitrobenzene.
- Reacting hydrogen and nitrobenzene in the presence of a catalyst in a hydrogenation reactor to form a crude reaction product.
- Analyzing the composition of the crude reaction product continuously or at regular intervals to determine the proportion of by-products.
- Taking measures to prevent nitrobenzene from breaking through in the hydrogenation reactor in case of an increase in the amount of by-products.
Potential Applications: - Chemical industry for the production of aniline, which is used in the manufacture of various products such as dyes, pharmaceuticals, and rubber chemicals.
Problems Solved: - Ensures the production of pure aniline by monitoring and controlling the formation of by-products during the hydrogenation process.
Benefits: - Improved efficiency in aniline production. - Reduction in the formation of unwanted by-products. - Enhanced product quality and purity.
Commercial Applications: - This technology can be utilized by chemical manufacturers for large-scale production of aniline, catering to industries that require this compound for their products.
Questions about the technology: 1. How does the continuous analysis of the crude reaction product help in improving the production process? 2. What are the specific measures taken to prevent nitrobenzene breakthrough in the hydrogenation reactor?
Original Abstract Submitted
The invention relates to a process for producing aniline by catalytic hydrogenation of nitrobenzene comprising: (a) reacting hydrogen and nitrobenzene in the presence of a catalyst in a hydrogenation reactor, forming a crude reaction product; (b) working up the crude reaction product to obtain pure aniline, wherein the composition of the crude reaction product is analysed continuously or at regular time intervals before starting working-up in (b), for determining the proportion of by-products, wherein, in the event of an increase in the amount of by-products, measures are taken to prevent nitrobenzene from breaking through in the hydrogenation reactor.
