Continuous nitration technology for trifluoromethylbenzene

2026-08-19 14:43:04

The nitration reaction of fluorinated aromatic intermediates is highly exothermic and has a high safety risk, which is a key challenge in the production of fluorinated fine chemicals. This technology uses a continuous process route to nitrate 3-fluoro-methoxybenzene, achieving precise dosing, rapid mixing, and instant heat transfer of materials through microchannels or continuous kettle reactors, significantly reducing the reaction volume and, from a fundamental perspective, reducing the risk of thermal runaway, while also inhibiting side reactions such as poly-nitration, thereby improving the selectivity and batch stability of the target products. The 3-fluoro-methoxynitrobenzene intermediates produced are widely used in the pharmaceutical, pesticide, and fluorinated functional materials industries. The technology has been built and commissioned in pilot facilities, which have verified the feasibility of the process and have the basis for process scaling. It is suitable for enterprises engaged in the production of fluorinated fine chemicals that place a high value on intrinsic safety. The enterprise must have the corresponding raw material supply and utility engineering support conditions.

Technique for the oxidation of methylacetophenone to vanillin

2026-08-19 14:42:53

Cinnamaldehyde (2-methoxybenzaldehyde) is a widely used aromatic aldehyde in the fragrance, pharmaceutical and daily chemical industries. This technology uses 2-methoxybenzene as raw material and catalyzes the selective oxidation of benzyl methyl to produce cinnamaldehyde. The key to the process is the precise control of the oxidation degree - ensuring high-efficiency conversion of the methyl group and inhibiting further oxidation to cinnamic acid. The catalyst system and process conditions have been optimized, resulting in a pure and stable product. Compared with the traditional chlorination hydrolysis route, this process produces no chlorine-containing waste and is more in line with green production requirements. At present, a pilot plant has been built and commissioned, which has verified the feasibility of the process and has the basis for process scale-up. It is suitable for fragrance chemical producers and fine chemical enterprises. The service provided includes process package authorization, basic design support, oxidation reaction and distillation equipment selection recommendations, commissioning guidance and operation training.
