Bis(2-ethylhexyl) maleate → 2-Ethylhexanol

Participants

Reaction Steps

The resulting solution of di-(2-ethylhexyl) maleate in 2-ethylhexan-1-ol is treated with hydrogen, in a trickle procedure, over a Cu/Mg silicate catalyst, at 190° C. and under a pressure of 200 bar, and the ester is cleaved to give butane-1,4-diol and 2-ethylhexanol. The mean space-time yield in a 3,300 hour experiment is 40 g of butanediol per liter per hour.
