Chem people, do we still use CCl4 outside of research?

Although, we've never used the real thing in the lab, our class and organic chem class use it all the time in equation.

Are those obsolete reactions or do we still use CCl4 in real life outside of labs?

No, most of the uses it had have been banned in the US, aresols, refrigerants, etc so I think it's only used in a few industrial processes used to make some other refrigerants.

jeez no.

It is used as a starting point for making other compounds, it just can't be used where it can be released into the air. We use it at times as a solvent in tests looking for other compounds. We also use CCL3H and CCl2H2 as solvents to extract target analytes from water. The EPA is still looking for replacements for these to reduce environmental contamination.

CCl2H2, methylene chloride is still commonly used everywhere. It's the main component of many paint strippers.

CCl4 use to be a pretty popular p-type dopant in arsenide and phosphide epitaxial growth. It's still used. It's not really uncommon.

We use CBr4 these days. The chlorine tends to do more etching than the bromine (especially in CVD growths where they've got all that hydrogen around), and it messes with your growth and surface morphology.

Got it??
