Softening thermoplastic polyurethanes using ionomer technology
In one or more embodiments, the present invention provides a novel approach to the addition of plasticizers for softening TPUs, i.e., lowering the durometer and the melt viscosity. This approach involves incorporating bonded sulfonate groups with quaternary ammonium counterions into the TPU.

Optimization of 2-EH product recovery system using process intensification
Systems and methods of recovering 2-ethyl hexanol from crude alcohol are disclosed. The crude alcohol originates from a reactor that produces 2-ethyl hexanol and is first distilled in a first distillation column The distillate from the first distillation column is then further distilled in a second distillation column. A side stream is drawn from the second distillation column and recycled to the reactor that produces 2-ethyl hexanol. The bottom stream from the second distillation column is mixed with the bottom stream from the first distillation column. The combined stream is further distilled in a third distillation column to produce a 2-ethyl hexanol product stream. |
