Method for the Recycling or Disposal of Halocarbons

The present invention relates to a method for recycling and/or disposal of halocarbons, particularly fluorinated alkanes, such as trifluoromethane, by reacting said halocarbons with sulfur trioxide, particularly to form halide sulfonic acids and sulfur dioxide.

Chloromethyl chlorosulfate: A new, catalytic method of preparation and reactions with some nucleophiles

A catalytic method of preparing chloromethyl chlorosulfate (CMCS) was described. The reaction of liquid SO3 with CH2Cl 2 at room temperature led to SO3 insertion into the C-Cl bonds, giving CMCS. The product mixtures consists entirely of CMCS and the product of further sulfation, methylene bis(chlorosulfate) (MBCS). The reaction was shown to be first order in the catalyst and third order in SO3 by measuring initial rates of CMCS formation or total CH2Cl2 consumption. The results show that the reaction between dichloromethane and SO3 at room temperature is accelerated by very low concentrations.
