Studies on the direct fluorination of the acidic imide (CF3SO2)2NH and of its lithium salt (CF3SO2)2NLi have enabled us to establish a potentially-viable commercial route to N-fluorobis(trifluoromethanesulfonyl)imide, (CF3SO2)2NF, and to carry out ha

Global warming impact (GW) of automobile air-conditioners using two refrigerants — a hydrocarbon blend and HFC-134a -were estimated and compared. The HFC-134a system showed a GW 20–90% greater than that of the hydrocarbon system. Volatile organic
