High-viscosity solid slurry realizes continuous nitrification. The first 10,000-ton unit in China was successfully started up

On April 14, Lily Flower Group Co.

The actual operation results prove that the micro-channel continuous device improves the safety and product quality of the nitrification reaction in the high-viscosity solid slurry system

Nitration reaction is an extremely important chemical reaction.

Dr.

In order to realize the reaction safety of nitrate-containing organic pigment intermediates, the R&D team headed by Dr.

They initially chose a traditional static microchannel reactor for their experiments

In order to overcome this technical problem, Dr.

According to the material characteristics and reaction characteristics, the Guizhou Microchemical research team has developed the HL small-scale reactor in a targeted manner

　　In order to realize industrialization, the scientific research team of Guizhou Microchem has carried out a pilot scale-up design based on the characteristics of the organic pigment nitration reaction, further optimized the reactor, and made several improvements to the supporting equipment and public works of the reaction system

　　After several improvements, the first 10,000-ton-level high-viscosity solid slurry system micro-channel continuous nitrification reaction device finally achieved a successful start-up in Lily Flower Group, breaking the only technology for high-viscosity solid slurry organic pigment intermediate synthesis.
