Transesterification of propylene glycol methyl ether by reactive simulated moving bed chromatography using homogeneous catalyst

Autor: Alfred K. Schultz, Megan E. Donaldson, Yoshiaki Kawajiri, Balamurali Sreedhar, Timothy C. Frank, Andreas S. Bommarius, Jungmin Oh

Publikováno v: Adsorption. 24:309-324

A reactive chromatography process was investigated for a transesterification reaction of propylene glycol methyl ether (DOWANOL™ PM) using a homogeneous catalyst, a sodium alkoxide. In the proposed process, fresh catalyst is supplied with desorbent

Model-based design and experimental validation of simulated moving bed reactor for production of glycol ether ester

Autor: Jungmin Oh, Alfred K. Schultz, Timothy C. Frank, Andreas S. Bommarius, Balamurali Sreedhar, Gaurav Agrawal, Megan E. Donaldson, Yoshiaki Kawajiri, Shan Tie

Publikováno v: Chemical Engineering Journal. 301:188-199

This work proposes a practical and systematic model-based approach to identify the optimal operating conditions for a simulated moving bed reactor (SMBR). The SMBR operation is applied to an industrial case study for the continuous production of a so

Transesterification of propylene glycol methyl ether in chromatographic reactors using anion exchange resin as a catalyst

Autor: Timothy C. Frank, Andreas S. Bommarius, Alfred K. Schultz, Jungmin Oh, Megan E. Donaldson, Yoshiaki Kawajiri, Balamurali Sreedhar

Publikováno v: Journal of Chromatography A. 1466:84-95

Reactive chromatography using an anion exchange resin is proposed for a transesterification reaction of propylene glycol methyl ether (DOWANOL™ PM) with ethyl acetate to produce propylene glycol methyl ether acetate (DOWANOL™ PMA). This reaction

Determination of methylene bridge crosslinking in chloromethylated PS-DVB resins

Autor: Steve Rosenberg, Javier Read de Alaniz, John C. Rohanna, Alfred K. Schultz, G. Leslie Burnett

Publikováno v: Journal of Polymer Science Part A: Polymer Chemistry. 54:1955-1960

We present the development of a method for the determination of methylene bridge crosslinking in 13C-labeled chloromethylated polystyrene-divinylbenzene resins. Our system uses a new room temperature reduction of the chloromethyl groups that circumve
