2,6-Dimethyl naphthalene can be used to make PEN an analog of PET. DM naphthalenes can be isomerized only within their triad. Here’s a way to get around that limit and make more 2,6-DMN. #catalysis 🧪 #isomerization patents.google.com/patent/WO199...

Kinetic are usually studied when you measure concentrations of key species. But what if you only know a property that does not have a zero that equates to zero concentration? Here’s how to measure Ea without concentrations or assuming a reaction order. #catalysis 🧪 pubs.acs.org/doi/10.1021/...

Many Hydrocracking cats use Pt on an Al-zeolite. But if you use a B-zeolite you see that the activity is the same, but the products are almost exclusively heavier n-paraffins and no C1. Need to have no Al. What is the mechanism? #catalysis #zeolite 🧪 patents.google.com/patent/WO200...

You won’t hear about this from the CDC or NIH etc because they have been muzzled. www.cidrap.umn.edu/tuberculosis... #tuberculosis #kansas #health

People involved in catalysis know bi-functional heterogeneous catalysts. All, I believe, use an acidic component. Here’s an exception which couples dehydrogenation and olefin metathesis components and no acid. Are there others? #catalysis #metathesis 🧪 link.springer.com/article/10.1...

I’m glad to have this paper published. In addition to helping refiners deal with Hg, the kinetics are the same at atm pressure and 1000 psig as measured by different methods. #mercury #refining #distillation 🧪 www.authorea.com/users/777384...

I like this site. However, I get many followers who look to be catfishing. If I start a conversation and don’t respond promptly several have said the same line “have you been abducted by aliens“. If I do engage they want to go to WhatsApp. Any way to deal with this? Not what I’m looking for.

I just made our vacation home in grass Valley, California available on Airbnb to families displaced by the Los Angeles fires. If you have a similar vacation home, please consider making it available. #LAfires #AirBNB www.airbnb.com/rooms/313107...

As an undergrad at Penn State I used to explore caves. We never found the end to this one. Anyone else a spelunker? Did you see J4? 🧪 #cave #spelunking youtu.be/S7rI0EisHs8
