Abstract
A process is disclosed for the preparation of vanadium trineodecanoate to used as one component of a promoter used in conjunction with a catalyst to cure a polyester resin. Vanadium pentoxide is reacted or reduced in an acidic solution. The resultant mixture is heated and thereupon neodecanoic acid triethyl phosphate, paraformaldehyde and xylene are added. This solution is azeotropically distilled. Vanadium trineodecanoate is recovered in a xylene phase.
Claims1
A process for the production of vanadium trineodecanoate to be used with a promoter as a catalyst comprising the steps of:
- reducing vanadium pentoxide in an acidic solution of formic and hydrochloric acids to form a vanadium (III) solution;
- heating said vanadium (III) solution under nitrogen for a period of time at 80.degree.-90.degree. C.;
- adding neodecanoic acid, triethyl phosphate, paraformaldehyde and xylene to said heated vanadium (III) solution to form a heterogeneous solution;
- heating said heterogeneous solution rapidly to reflux with stirring;
- azeotropically distilling said heterogeneous solution under nitrogen to remove the aqueous phase;
- and
- recovering said vanadium trineodecanoate in a xylene solution.
