Honeydew from the Land of Oilrigs and Cowboys

I have been in Alberta attending chemistry conferences this last week. I made three presentations to good attendances and kind comments. Did some networking (I actually had people sliding their business cards into my hand in passing and giving me the "call-me" gesture) and re-newed some old friendships.


But most of all I attended seminars and lectures.


All about chemistry.


All of them using Powerpoint.


From 8 AM to 8 PM.


For five days.


Man, my brains are dribbling out my earholes.


I must admit to not really adjusting to the Alberta lifestyle so well. It seems to largely feature driving fast and recklessly in large pick-up trucks. Yes, gas is $ 1.30 a liter out here but I guess that is just part of the package. I just left Taco Bell reflecting to myself that I had just come to Alberta to purchase "Mexican" food prepared entirely by Chinese immigrants (they had one designated English speaking woman who shouted orders at the crew in Mandarin). Welcome to the wild west.


I spent the better part of one day listening to the Green Chemistry / Petroleum Chemistry people. I pass for clever in some parts and God-like omniscient in some others but I had a hard time cutting through the language of some of those folk. In one talk it came out that the Petroleum industry has just committed one billion $ for sequestration of CO2. Even in Alberta that is the kind of money that makes people slow down to look. Sequestering CO2 is collecting it and hiding it in mineral formations either chemically as carbonates or under pressure. What is amazing is that after listening to some of the best scientists in the area I could only conclude:

1) at this time we do not have a process that works for any more than 0.1% of (*current*) CO2 emissions

2) that China is currently bringing a new dirty coal fired electrical plant online everyday (yes kids, e-v-e-r-y-d-a-y)

3) if we were to discover a process today that worked, the industrialisation, ethics and environmental approval process in North America would mean that viable use could not occur for 10 years. We do not have such a process.


In terms of CO2 we are totally screwed. The genie is out of the bottle. We have lived a blessed and extravagant lifestyle in front of a watching world for several generations now and they feel entitled to the same thing. Very soon every family in China, India and Indonesia will want a computer, a car and a refrigerator.


After listening, talking and thinking I was only able to conclude one thing. The ONLY short and long term solutions that we have to atmospheric CO2 are to stop emissions and to plant trees. We seem to be socially incapable of the former but I have hopes for the latter. It was therefore amazing to read an article in the New York Review of Books by Freeman Dyson (LINK) that essentially says that we do not have the time or ability to create new industrial processes to solve the CO2 problem once we emit CO2. Dyson said that we DO have the ability to genetically manipulate trees to make them "carbon eating". In my opinion that is brilliant. The only working process that we know of that gets rid of atmospheric CO2 is the natural plant carbon cycle. We just need to tweak the genetic thingees in the trees and they will save us. Tolkien was right, our salvation rests with the ents. We will all soon be tree - huggers.


I'm comin' home.

Chemistry In the News: The Perils of Modern Life

Canada has a list of industrial chemicals that it considers "toxic" [Link to gov't site]. It has been announced that the list has been just increased by 11 more. It is somewhat alarming that some of the chemicals listed as cosmetics additives or additives to plastics that are in your house right now. Actually the whole cosmetics industry has not covered itself with glory from the get-go. I mean the reality of the cosmetics industry is two-fold: 1) to give a false impression and 2) to achieve goal #1 at any and all cost. There are people out there who would gladly trade a shorter life for "looking good". The illusion of a healthy glow has been achieved for centuries by coating the face with compounds of mercury or antimony and 11 doctors out of 10 will tell you that is a bad bad idea. Indeed, the plastics industry has always tweaked the properties of the pure plastics with additives to suit the end use and the attitude has always been that the additives have not been mobile once Incorporated in the plastic. That would appear to have been an assumption of disputable validity.

The whole moving to a shack in the woods and living off the land is looking better all the time.


The Additions to the Toxic List
(Links to mostly Wikipedia (click on name))*

1] Acetic acid ethenyl ester [Vinyl acetate] Linked to cancer. Used in products such as abrasives, fragrances, perfumes and deodorizers.
Now this is just unfair, it is a nice volatile compound with a pleasing odour and has served us well for centuries and now we turn our backs on it for causing cancer.

2] 1,3-Butadiene, 2-methyl [Isoprene] Linked to cancer. Used in rubber and plastic manufacturing. But, but, but ... it's a NATURAL compound! Nature wouldn't hurt us would it? I mean just who is in charge here maybe we should just show Nature who's the boss. Yeah, that's what we will do. We will kick old Nature right where it hurts, we will pollute the ground, water and air and spit in Nature's eye and tell it to do its best. I mean really what can it do if we drag chemicals out of all natural chemical contexts and use the chemicals in ways that Nature never intended?

3] Thiourea Linked to cancer. Used in electronic products, mining, textiles, dry cleaning and hair preparations and cosmetics. I like this compound I like it alot. I can think of chemical reactions I would like to do with this chemical if I had a nice dark lab and a warm retort (look it up kids it only sounds dirty).

4] Oxirane Linked to cancer and persistent in the environment. Used in epoxy resins for paints, coatings, adhesives and other products, and to produce synthetic glycerin. This has just gotta be the coolest compound on the toxic list. No organic modelling kit will allow you to build this simple molecule because three membered rings are supposed to be rare and unstable and yet I can bet that you have driven down the road and have been passed by a tanker transport of this stuff. Cool but it will tear into organic compounds like a rabbit into wet sand.

5] C.I. Pigment Yellow 34 [chromate yellow] Contains chromium and lead. Linked to cancer. Used as colorant in plastics, inks, paints, coatings, adhesives, textiles and sealants, artists' supplies, cars, vinyl packaging, toys.
I got nothing on this one I would have thought eliminating lead and chromium would have been taken care of years ago. I guess traditional use trumps risk. If you tried to bring something like this on the market now as a new compound you would never get it onto the North American market except in Thomas the Tank Engine toys.

6] C.I. Pigment Red 104 [molybdate orange and molybdate red]
Contains chromium and lead. Linked to cancer, a developmental and reproductive toxin. Colorant for red to orange. Used in paints, coatings, dyes, inks, plastics.

7] Benzenesulfonic acid [Acid Blue] Deemed an environmental hazard. Used in cleaners and disinfectants.
8] Cyclotetrasiloxane, octamethyl [D4]
Deemed an environmental hazard. Used in construction, textiles, leather and hide tanning, paper products, plastic packaging, household appliances, computers, motor vehicle parts and cleaning compounds.

9] Cyclohexasiloxane, dodecamethyl [D6] Deemed an environmental hazard. Used in cosmetics, beauty supplies, perfumes, personal care products, pharmaceuticals and drug products, paper bags and paper products, rubber products, medical equipment and supplies, cleaning compounds, polishes, foods, paints, coatings and adhesives. Building blocks of silicone, application includes breast implants.

10] Cyclopentasiloxane, decamethyl [D5] Deemed an environmental hazard. Used in health and personal care products, footwear, automotive parts, construction, mining and oil/gas extraction, transportation, warehousing and storage, pharmaceuticals, toiletries and cosmetics. Building blocks of silicone, application includes breast implants. This is one fancy family of environmentally hazardous chemicals. The cyclic siloxanes have an amazing and surprising chemistry and the fact that they went from lab to industry so fast is a measure of the niche that they occupy. Makes me wonder what they have to replace these guys. I got to say that this really makes me reconsider the pectoral and butt implants I was thinking about.

11]Phenol, 2,4,6-tris [1,1-dimethylethyl][2,4,6-tritert-butylphenol]
Deemed an environmental hazard. Used as a fuel additive.
OK, now just wait a minute, this is super mesityl phenol. I mean how can you list a chemical with "super" in its name? Who is going to protect us now when we really need an organic oxidant?
