Halide-free and noble metal-free pyridine-modified H-mordenites exhibit high stability and selectivity in methanol carbonylation to acetic acid.

A green route for methanol carbonylation

 Author affiliations

Abstract

Acetic acid is one of the most important bulk commodity chemicals and is currently manufactured by methanol carbonylation reactions with rhodium or iridium organometallic complexes and halide-containing promoters named Monsanto or BP Cativa™ homogeneous processes, respectively. Developing a halide-free catalyst and a heterogeneous process for methanol carbonylation is of great importance and has recently attracted extensive research attention. Here, we report a green route for direct synthesis of acetic acid via vapor-phase carbonylation of methanol with a stable, selective, halide-free, and noble metal-free catalyst based on pyridine-modified H-mordenite zeolite. Methanol conversion and acetic acid selectivity can reach up to 100% and 95%, respectively. Only little deactivation is observed during the 145 hour reaction.

  3. The expense of getting a fiend through drug rehab is generally 25% of the expense of keeping them in jail - $26,000 for jail, $6,000 for drug rehab. A few people object to supporting or helping drug addicts in any capacity. They think the fanatic got himself into that position, for what reason should citizens pay for him to receive in return? The truth of the matter is, we're paying for it somehow. Our charges not just compensation for the a huge number of individuals in jail - which adds up to many, a huge number of dollars consistently - we additionally take care of everything for a considerable lot of the tens or countless clinic trauma centers visits, both for individuals on drugs and for the individuals who have been harmed in some drug-related wrongdoing or mishap, we pay the funeral home expenses for overdoses, we pay higher medical coverage, higher vehicle protection, and we uphold openly supported drug rehab and other therapy places.
