  • Process for preparing 1,1,1-trifluoro-2, 2-dichloroethane
    Publication number: 20070032688
    Abstract: The invention relates to a process for preparing 1,1,1-trifluoro-2,2-dichloroethane (F123). This process consists in placing 1,1,1-trifluoro-2-chloroethane (F133a) in contact with chlorine in the presence of hydrogen fluoride and a fluorination catalyst. F133a may be obtained by fluorination of trichloroethylene, and the F123 may be subsequently fluorinated to F125.

  • Bituminous emulsions, their method of preparation and their use for the production of materials and road pavements
    Publication number: 20060086288
    Abstract: The present invention relates to bitumen emulsions that can be used in roadmaking applications for the production of cold mixes, emulsion-stabilized gravel and road pavements obtained at ambient temperature, the cohesion of which at young age is substantially improved over the cold mixes, emulsion-stabilized gravel and road pavements of the prior art. These bituminous emulsions are characterized by a median diameter of 0.6 ?m or less, and preferably 0.5 ?m or less.

  • Process for the preparation of 1,1,1-trifluoro-2,2-dichloroethane
    Patent number: 6590130
    Abstract: The invention relates to a process for the preparation of 1,1,1-trifluoro-2,2-dichloroethane (F123). This process consists in bringing 1,1,1-trifluoro-2-chloroethane (F133a) into contact with chlorine in the presence of hydrogen fluoride and of a fluorination catalyst. The F133a can be obtained by chlorination of trichloroethylene and the F123 can subsequently be fluorinated to F125.
