HCID 5437051-Butene, 3-butoxy-HCID 5439041-Butoxybut-2-ene

Procedure

A 0.3 1 stirred autoclave was filled with 67.0 g (0.90 mol) of n-butanol and with 11.5 g of Lewatit® SPC 118 in the H+ form, which had been washed beforehand with water and n-butanol, and with 3.5 g of a Lewatit® SPC 118 ion exchanger doped with copper(II) chloride. 47.0 g (0.88 mol) of 1,3-butadiene were then forced into the autoclave. After reaction for 10 hours at 90° C. and under autogeneous pressure, a selectivity of 46.8% for 3-butoxybut-1-ene and a selectivity of 44.3% for 1-butoxybut-2-ene (based on butadiene) were obtained at a conversion of 69.1%.
