The subject of the invention is a process for the preparation of a catalyst based on Sn (II) 2-ethylhexanoate, by reaction of SnO with 2-ethylhexanoic acid, under reduced pressure, with the removal of water from the reaction medium, in which SnO and ethylhexanoic acid are used in stoichiometric amounts, the reaction is carried out at a temperature of 85 ° C to 125 ° C, and during the reaction toluene is added to the reaction mixture in an amount of 40 - 100% based on the weight of SnO used, and the toluene-water azeotrope is drained, after which toluene residues are removed. |
