Abstract
Solvents or solvent compositions comprising HCFC-234. The solvents can be used, instead of CFC-113, as solvents, diluents, cleaning agents, drying agents or dispersing agents. The solvent compositions of HCFC-234 with an aliphatic alcohol having 1 to 4 carbon atoms or with cyclohexane can give azeotropic compositions.
