Which brother has the feasibility study for 1,1,1-trifluoroethane? Could you share it for reference?

It’s really difficult to create something from scratch without any reference materials. Thank you all for your hard work. There’s very little information available online about 1,1,1-trifluoroethane; it’s impossible to find any details. I even suspect that only a few companies produce this substance
143a？ Partial chlorofluorination is done in one step.
Rarely, I guess. We produce 134a; one of the side reactions results in 143a. It used to be recycled and refined, but now almost no one wants it; it’s simply discharged, in small quantities.
