Uses

Used in Chemical Industry:
Ethane, 1,1,1-trichloro-2-nitrois used as a solvent and in the manufacture of other chemicals due to its unique properties and reactivity.
However, it is important to note that 1,1,1-trichloro-2-nitroethane is considered toxic when ingested or inhaled and can cause irritation to the skin, eyes, and respiratory system. It also has potential environmental impacts, as it is persistent and may bioaccumulate in the environment. Therefore, it should be handled and used with caution, and appropriate safety measures should be taken when working with this chemical.

1. 1 - Dichloro - 2 - nitro-ethylene and synthesis method of nitenpyram (by machine translation)

The present invention provides a 1, 1 - dichloro - 2 - nitro-ethylene and nitenpyram synthetic method. 1. 1 - Dichloro - 2 - nitroethylene synthesis method, comprises the following steps: the 1, 1, 1 - trichloro - 2 - nitro-ethane with caustic soda in a microchannel reactor reaction, the obtained product delaminated, congeals the feed liquid, is 1, 1 - dichloro - 2 - [...]. The invention in the micro-channel is performed in a reactor, which has a large specific surface area, can improve the 1, 1, 1 - trichloro - 2 - nitro-ethane with caustic soda contact efficiency, thus improving the response of the raw materials, to improve the product yield. By using micro-channel reactor, 1, 1 - dichloro - 2 - nitroethylene yield as high as 90% or more, and also to increase the purity of 90% or more. This from the side also illustrate the invention to improve the utilization rate of caustic soda, alkali caused by pollution, salt pollution the intensity is reduced, to reduce the difficulty of tail water treatment.

Improved preparation method of nitenpyram

The invention relates to an improved preparation method of nitenpyram. The method comprises steps as follows: firstly, 1,1-dichloroethylene has a reaction with a nitration agent comprising hydrochloric acid and sodium nitrate to generate 1,1,1-trichlorine-2-nitroethane, and the 1,1,1-trichlorine-2-nitroethane has an elimination reaction with NaHCO3 to generate a 1,1-dichlorine-2-nitroethylene intermediate; secondly, 2-chlorine-5-chloromethylpyridine has a reaction with ethylamine, and an ethylamine intermediate is prepared; thirdly, the ethylamine intermediate has a reaction with 1,1-dichlorine-2-nitroethylene intermediate and monomethylamine, and the final product nitenpyram is generated. NaNO3 is used to replace traditional nitric acid to serve as a target phase transfer catalyst, the reaction selectivity is improved, the yield is higher, and the operation is safer.
