Latest Patents

Takeshi Asanawa holds a patent for a continuous process for preparing chlorotrifluoroethylene. This patent describes a method that utilizes a known reaction of 1,1,2-trichloro-1,2,2-trifluoroethane (R-113) with zinc powder dispersed in an alcohol, such as methanol. The invention aims to facilitate the industrial preparation of CTFE in a continuous manner, enhancing efficiency and productivity. The process involves a series of stirred tank reactors, typically two or three, connected by overflow pipes. A dispersion of zinc powder is continuously fed into the first reactor, allowing it to overflow into subsequent reactors, while R-113 is also continuously introduced. The CTFE is discharged continuously from each reactor, and the zinc is gradually converted into zinc chloride, achieving a conversion rate of 90% or above in the last reactor.
