I always get a kick out of smug Mac users thinking their computers are safe from viruses. Looks like Mac users may have something else to worry about :thumbsup:

Bogus? - free benzene"..."musty" smell"?

 

Benzene is an aromatic organic chemical - its' smell is delicious... In college chem labs way back then, we'd clean our glassware with it, followed by acetone to dry. What a hit. :lol:

It does give you a headache. In organic chem, we had an experiment using benzene. The TA forgot to turn on the fume hood exhausts for most of the class. Most of us had a splitting headache the rest of the day. The next week they said it was a carcinogen and the experiment was dropped from the class the next semester.

Impossible!!!

 

Mac's are perfect! The even have "Genius's" to help out poor PC users switch to Mac's

 

Must have been a Typo, and obviously made on a PC since the Mac wouldn't create something with a typo. I will only believe it if they say that Mac's CURE Cancer

Well, if you were taking organic chem - not a featherweight subject of study - you certainly should have known beforehand about benzene's health effects.

 

There is a switchplate beside a fume hood, ganged next to the light switch, that activates the updraft - that's why they are called fume hoods. Pretty easy to figure out, and then turn it on yourselves?

 

Something here doesn't connect properly...:thumbsup:

It was the major teaching lab at UB and back in the 70s there was a switch to turn on all the hood ventilation systems in the lab. They didn't trust the undergrads to turn them on by themselves. And thinking back, it may have been the Chem 101 course. This was over 30 years ago.

right...you probably liked the smell of methyl mercaptan too. :worthy:

No. But if you want a degree in chemistry, you nut up and take it.

 

I was a medium noise in a biz that manufactured dialkyldithiophosphate compounds for a while. Primary alcohols reacted with phosphorus pentasulfide under heavy heat in a 12 ton Rx vessel while the sealed reactants cooked with a 100 lb pressure of N2 gas for blanketing, then hundreds of gallons of chilled water washing over the reactor vessel per minute when the Rx pressure dropped - wasn't that special? :lol:

 

The sold product was used as the anti-wear, anti-oxiditation additive for lubricating and hydraulic fluids. Ubiquitous. Every lubricant needs it.

 

One of the products was flat-out fascinating. It was psuedoplastic; shear-thickening.

 

After the P2SO5/alcohol Rx, that intermediary went over for admixture with MnO2. Much heat produced. We sold the process by-product NaSH to the leather tanning crowd, and occasionally, some free acid product to the rubber vulcanization biz. That stuff was bad news. See Sarin...

 

Long before I showed up at this place, there was an explosion that coated several workers with P2S5 powder. You know what happened to them. The Plant Manager at the time drank himself to death within a year.

 

Have you considered a career in the exciting field of dimethyl mercury research? :lol:
