| description | The invention relates to a process for recovering noble metals from electric and electronic waste by means of
a) adducts with alogens of cyclic dithioxamides of formula (1)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ R,R' dazdt·nX 2 €ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein:
R and R' are the same or different alkyls,
X 2 are the same alogen or inter-alogen, and
N is 1 or 2;
b) adducts with alogens of non cyclic dithioxiamides of formula (2)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ R,R'DTO·nX 2 €ƒ€ƒ€ƒ€ƒ€ƒ(2)
wherein:
R and R' are the same or different alkyls or aryls,
X 2 are the same alogen or inter-alogen, and
N is 1 or 2;
c) adducts with alogens of tetralkylthiuram disulphide (Bis(diethylthiocarbamoyl)disulphyde) of formula (3)
wherein:
R and R' are the same or different alkyls or aryls, and
X 2 are the same alogen or inter-alogen; and
d) adducts with alogens of dimorpholinthiuram disulphyde (Bis(morpholinthiocarbamoyl) disulphyde) with morpholine as the only substituent of the nitrogens, having formula (4)
wherein X 2 are the same alogen or inter-alogen. |
