| titleOfInvention | Method of production of extractant for palladium and platinum |
| abstract | SUMMARY OF THE INVENTION: gas condensate containing 0.30-0.37 wt.% Mercaptano. $ sulfur, is subjected to treatment with an extractant containing diethylene glycol, a 30% aqueous solution of formaldehyde and a 20% aqueous solution of sodium hydroxide at a volume ratio of 1: (0.4-0.6) :( 0.04-0, 06) respectively. The treatment is carried out for 20-30 minutes at room temperature and a volume ratio of extractant and gas condensate equal to 1: (10-13). The resulting extract is treated with acetone at room temperature and an array of the ratio of extract to acetone equal to 1: (0.018-0.045). Extraction of the expected product is carried out with diethyl ether. 3 tab. |
