Abstract
A process for hydroxylating aliphatic compounds under catalytic distillation conditions to provide alcohols is provided. The aliphatic compound is contacted, in a distillation column reactor, with an oxidation catalyst and an oxidant under conditions effective to hydroxylate the aliphatic compound while maintaining at least a portion of the aliphatic compound in a liquid phase and separating the hydroxylated product from the un-reacted aliphatic compound in the distillation column reactor.
Claims37
A process comprising:
- continuously contacting, in a distillation column reactor comprising a reaction zone and a distillation zone, at least one, saturated or unsaturated, aliphatic compound having carbon atoms in the range of 6 to 30 with an oxidation catalyst and an oxidant under conditions effective to hydroxylate said aliphatic compound thereby producing a hydroxylated product, while maintaining at least a portion of said aliphatic compound in a liquid phase;
- continuously separating said hydroxylated product from the un-reacted aliphatic compound in the distillation zone under conditions effective to vaporize said un-reacted aliphatic compound and maintain said hydroxylated product in a liquid phase;
- and
- recovering the said separated hydroxylated product from the distillation column reactor.

A process comprising
- continuously contacting, in a distillation column reactor comprising a reaction zone and a distillation zone, at least one, saturated or unsaturated, aliphatic compound having carbon atoms in the range of 6 to 30 with a molecular sieve catalyst and an oxidant at a temperature in the range of about 50° C. to about 450° C. and a partial pressure of the aliphatic compound in the range of about 0.01 atm to about 40 atm thereby producing a hydroxylated product, while maintaining at least a portion of said aliphatic compound in a liquid phase;
- continuously separating said hydroxylated product from the un-reacted aliphatic compound in the distillation zone under conditions effective to vaporize said un-reacted aliphatic compound and maintain said hydroxylated product in a liquid phase;
- and
- recovering the said separated hydroxylated product from the distillation column reactor.
