Vapor Phase Oxidation Of Chloropropenes Over Heterogeneous Catalyst Systems, Tim Ellis Owen
Retrospective Theses and Dissertations
Propylene Dichloride (PDC) is a byproduct of several Dow processes. The thermal cracking of PDC produces 1-cis-chloropropene, 1-trans-chloropropene, 2-chloropropene, and allyl chloride . By oxidizing the l- and 2-chloropropenes to 3- and 2- chloroacrylic acids, respectively, a potentially valuable product could be made. The chloropropenes, air, and steam were passed over various heterogeneous oxidation catalyst systems to attempt this oxidation. Contact time was varied between 0.0951 to 0.915 sec. Temperature was varied between 275C to .25C. The air content of the feed was varied between .1 to 75%. The chloropropene content of the feed was varied between 2.9% to 5.0% …
