Abstract
A process for preparing a haloalkane comprising: (a) contacting a haloalkane starting material with a haloalkene starting material in the presence of an effective amount of a catalyst complex under conditions effective to facilitate an addition reaction and to form a product stream comprising a haloalkane product from said addition reaction, wherein said catalyst complex has a boiling point higher than that of said haloalkane product; and (b) recovering said haloalkane product from said product stream.
Claims32
A process for preparing a haloalkane comprising:
- (a) contacting a haloalkane starting material with a haloalkene starting material in the presence of an effective amount of a catalyst complex under conditions effective to facilitate an addition reaction and to form a product stream comprising a haloalkane product from said addition reaction, wherein said catalyst complex comprises a catalyst and an organic ligand selected from the group consisting of nitriles having a backbone of three or more carbons;
- amides having a backbone of two or more
- carbons;
- phosphates having a backbone of three or more carbons;
- primary amines selected from the group consisting of stearylamines, laurylamine, octylamine (liquid), 2-ethylhexylamine, 2-octylamine, tert-octylamine, diaminododecane (C12H28N2), hexamethylenediamine, and tetramethylenediamine;
- and combinations of two or more thereof;
- and
- (b) recovering said halo alkane product from said product stream.
