Process for isolating hydroxypivalic acid from aqueous solution |
| abstract |
Hydroxypivalic acid is obtained from aqueous solutions by removal of the water by azeotropic distillation and subsequent crystallization from a solvent mixture which is composed of a polar and a non-polar component. The distillation is carried out under reduced pressure and at a maximum bottom temperature of 90° C., until a residual water content of at least 0.1% of the total weight of the resulting solution is achieved. |
