Claims6
A process for making 3-pentenoic acid which comprises (1)reacting butadiene with carbon monoxide in the presence of nickel and an iodide source selected from the group consisting of HI and iodides of metals selected from the group consisting of B, Al, Ga, Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb, Lu, Ge, Sn, Ti, Zr, Cr, Mo, W, Mn, Fe, Co, Ni and Zn in a carboxylic acid-containing solvent at a temperature between about 60.degree. C. and about 140.degree. C. and a pressure between about 200 psig and about 4000 psig and (2) recovering 3-pentenoic acid.
