Usage

General Description

1,1,1,2,2,3,3-heptachloro-3-fluoro-propane, also known as HCFC-225ca, is a fluorinated solvent used in the electronics and precision cleaning industries. It is a colorless liquid with a high boiling point and low vapor pressure, making it ideal for use in cleaning applications. HCFC-225ca is considered a volatile organic compound (VOC) and is subject to regulations restricting its use and emissions due to its potential to contribute to ozone depletion and global warming. It has been phased out in many countries due to its environmental impact and is being replaced by safer, more sustainable alternatives. Despite its useful properties as a solvent, the potential environmental and health risks associated with HCFC-225ca have led to its decreasing use.

PHOTOCHEMICAL REDUCTION OF CARBON-HALOGEN BONDS. 3. REGIOSELECTIVITY OF THE REACTION IN FLUORINATED HALOGENOPROPANOATES.

The ester group exhibits a strong directive effect in the photochemical reduction of a carbon-halogen bond and directs the reduction in perhalogenated chlorofluoropropanoates of the type CFXY-CClZ-COOR (X,Y,Z = Cl, F) to the α-position in the acyl part of an ester.The reduction takes place with the same regioselectivity even in esters CFCl2-CHCl-COOR (10).In esters containing an α -CCl2- group the reductions to the first and the second stages can be separated and the individual reduction products can be obtained preparatively.The α C-F bond is more difficult to reduce and therefore in the ester CFCl2-CHF-COOR (11) the β C-Cl bond was reduced specifically and in the ester CF2Cl-CHF-COOR (12) both the α C-F bond and the β C-Cl bond were reduced parallely.The relative reactivity of fluorinated halogenopropanoates with an α C-Cl bond showed only small differences in the reduction with 2-propanol in the presence of acetone as a sensitiser; the quantum yield Φ reached values of about 28-35 under kinetic measurements and thus proved the existence of a chain radical mechanism.
