Synthesis method of florfenicol dimer impurity

Номер: CN116589389A
Принадлежит:

The invention relates to a synthesis method of a florfenicol dimer impurity. The synthesis method of the florfenicol dimer impurity comprises the following steps: (1) reacting a compound IV with p-nitrobenzenesulfonyl chloride to obtain a compound III; and (2) reacting the compound III with florfenicol amine, and cracking under an acidic condition to obtain a compound I which is a target product. The dimer impurity compound I is synthesized through a two-step synthesis method, the compound II obtained in the second-step reaction can be directly treated under the acidic condition without separation to obtain the compound I, the requirement for reaction conditions is low, the preparation process is greatly simplified, operation is easy, and the product purity is high and reaches 97%; simple purification can be used for qualitative and quantitative analysis of impurities.

Surface modified nanometer TiO2 particle, preparation method thereof, application and method for reducing content of p-nitrophenol in wastewater

Номер: CN0101966468A
Принадлежит:

The invention provides a surface modified nanometer TiO2 particle, a preparation method thereof, application and a method for reducing the content of p-nitrophenol in wastewater. The surface modified nanometer TiO2 particle comprises a nanometer TiO2 particle, the surface of which is combined with 1-hydroxy-2-naphthoic acid. In the invention, the 1-hydroxy-2-naphthoic acid including benzene ring is taken as a surface modifier to carry out surface modification on the nanometer TiO2 particle via a simple surface chemical adsorption method; meanwhile, the nanometer TiO2 reacts with an organic modifier by utilizing generalized acid and alkali properties of the nanometer TiO2 to generate similar esterification reaction and form a hexatomic ring compound with strong stability; and the benzene ring is bound on the surface of the nanometer TiO2 to improve the affinity for the aromatic pollutants.

Micro-positive-voltage cable bridge dustproof system

Номер: CN212935441U

In environments with serious dust such as coal mines and bulk cargo wharfs, a traditional cable bridge is difficult to restrain accumulation of the dust on the cable, so that the temperature in the cable is too high, and safety accidents are easily caused when the temperature rises seriously. According to the micro-positive pressure cable bridge dustproof system provided by the utility model, the air pump system is adopted to pressurize the interior of the groove-shaped cable bridge, so that the air pressure in the groove-shaped cable bridge is slightly greater than the external atmospheric pressure to form a certain air flow, thereby fundamentally avoiding safety accidents such as fire disasters caused by spontaneous combustion of coal dust due to cable temperature rise. And the device can be widely popularized and used in enterprises with severe working environments.

Technology for synthesizing sulfur quantum dots through oil-water interface method

Номер: CN103588178A
Принадлежит:

The invention discloses a technology for synthesizing sulfur quantum dots through an oil-water interface method. The technology comprises the following steps: 1, preparing metal sulfide quantum dots; 2, preparing a nitric acid solution; and 3, preparing sulfide quantum dots. In the invention, oleic acid is used as a solvent to prepare oil-soluble metal sulfide quantum dots, an n-hexane solution of a metal sulfide and an aqueous solution of nitric acid are mixed as an oil phase and a water phase respectively, nitric acid oxidizes sulfide ions into elemental sulfur in situ at the phase interface, and the metal sulfide quantum dots are adopted as a template to realize the uniform distribution of the particle sizes of the prepared sulfur quantum dots, so the oil-water interface alleviates the reaction speed and realizes the dispersion and small particle sizes of sulfur nano-particles. The technology allows the sulfur quantum dots to be synthesized by adopting the above technical scheme through ...
