What is 1,1,2-trifluroro 2,2,1-trichloroethane used for? A local teacher received several gallons of this stuff as part of a donation. I am trying to find it a home. I suspect it would be great for degreasing an engine, but I also suspect it may have more valuable uses.

I used to analyse for it as one of a series of aerosol can propellants. It has trade names of ICI Arcton F113 and DuPont Freon. It may well be one of the ozone depleting ones, which are now banned.

Regards,

Ralph

The donation was a self serving one. Disposal costs for this are quite excessive. I would give it back. Good luck.

Seems like a strange donation. What was the intended purpose of the donation? I think I used to use this for oil and grease extractions when I worked in an environmental lab, but I think the procedure may have been modified by now. There are a number of uses for chlorinated solvent in a chemistry lab, but I couldn't see this in a high school class.

I'm sure it would work good for degreasing an engine, but there may be some toxicity issues(use with good ventilation), and it is probably illegal.

check with an airconditioning firm in your area and see if they have any use for it. New products of this sort are extremely expensive due to the changes in the laws of most countries in recent years.

This was used for oil and grease extractions for years, but is no longer used because of the ozone depleting characteristics of the compound. I'm not sure it is legal to even use this for the application any more, but I am sure it has no legitimate use in a high school lab.

I am wondering if this was a legal way for the donor to dispose of it. Costs for waste disposal of chlorinated compounds can be high.

thanks to all. The "oil and grease " analysis was what I was lookin for. I figured it had some common use, at least at some time. I'll bet it was(is) costly.
