What is the specific method of implementation of trifluoroacetaldehyde hydrate?

Trifluoroacetaldehyde hydrate contains both trifluoromethyl and aldehydes and is widely used in synthetic resins, functional polymers, rubber, coatings, pharmaceuticals and pesticides. However, it is a gas at room temperature and easily combines with water to form hydrates, making it difficult to prepare, produce and transport. There has been little research into the preparation of trifluoroacetaldehyde hydrate and therefore mature production techniques and technologies cannot be produced.

What is the exact method of implementation of trifluoroacetaldehyde hydrate?

The preparation of trifluoroacetaldehyde hydrate consists of the following steps: trifluoroethanol, oxygen and nitrogen are preheated in a molar ratio of 1:1.833605 and injected into a fixed bed reactor. The reaction is carried out in the presence of a vanadium catalyst at 0.5 to 1 mpa and 120 ~ 200. The plutonium catalyst consisted of a primary catalyst and an auxiliary catalyst of molybdenum trioxide with a molar ratio of 533601 of zirconium dioxide, pentoxide and zirconium dioxide as the catalyst carrier with a productivity of 94.1%.

The preparation of trifluoroacetaldehyde hydrate comprises the following steps: trifluoroethanol, oxygen and nitrogen are preheated in a molar ratio of 1:1.833608 and injected into a fixed bed reactor. The reaction is carried out in the presence of a vanadium catalyst at 1 ~ 2 MPA, 200 ~ 350. The primary and secondary catalysts were selected for the plutonium catalyst, with the primary catalyst selected as pentoxide, the catalyst carrier selected as zirconium dioxide and the secondary catalyst selected as a mixture of molybdenum trioxide and fossil dioxide with a molar ratio of 1:1.2 and a molar ratio of pentoxide to zirconium dioxide of 533601 with a productivity of 94.3%.

Technical characteristics of trifluoroacetaldehyde hydrate:

Technical field of chemical synthesis, in particular the preparation of trifluoroacetaldehyde hydrate; said preparation comprises the following steps: trifluoroethanol, oxygen and nitrogen are mixed in a molar ratio of 1:1.833605 ~ 15 preheated and injected into a fixed bed reactor and reacted in the presence of a vanadium-based catalyst at 0.5 to 2.8 MPa and 120 ~ 450. The production process of the present invention is made by one-step oxidation of ethanol trifluoride, nitrogen and oxygen, and its catalyst is also a relatively inexpensive brominated metal oxide, which makes the production of acetaldehyde trifluoride hydrate much less expensive than other processes. In addition, the present invention saves resources by separating and recycling the reaction feedstock that is not involved in the reaction, and separates trifluoroacetaldehyde hydrate from the system easily.
