Ammonium hydrogencarbonate, reactions with

In the industrial process [12] 1,3-butadiene and water are reacted at 60-80 °C in an aqueous sulfolane solvent in the presence of triethylamine hydrogencarbonate under 10-20 bar CO2 pressure. The reaction yields linear telomers mainly, with a 90-93 % selectivity to 2,7-octadien-l-ol together with 4-5 % l,7-octadien-3-ol. Most of the products are removed from the reaction mixture by extraction with hexane, and the aqueous sulfolane phase with the rest of the products, the catalyst and the ammonium bicarbonate is...
