Halifax explosion- Benzol?
It's the anniversary of one of the largest acidental chemical explosions of all time-
Halifax explosion
Listed in the cargo among the explosives are several tons of "Benzol". AFAIK, that's an old term for phenol? Anyone know if this is what they're
referring to- I find the same cargo list in many other places as well.

Rapopart’s Rules for critical commentary:
1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it
that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.
Anatol Rapoport was a Russian-born American mathematical psychologist (1911-2007).

Quote: | At 7.30 a.m. on December 6, the French ship Mont-Blanc left her anchorage outside the mouth of the harbour to join a convoy gathering in Bedford
Basin. She was loaded with 2,300 tons of wet and dry picric acid, 200 tons of TNT, 10 tons of gun cotton and 35 tons of benzol: a highly explosive
mixture. |
Phenol is flammable but is not explosive . . .
The other cargo most certainly was!

They had barrels of flammable liquid all over the deck of the ships. Funny I remembered it as benzol being a name for benzene fuel...
In any-case, when the two ships separated the sparks ignited ruptured barrels which triggered the conflagration that eventually spread to the
munitions. The exploding barrels of boiling benzol made fighting the blaze impossible right up until the munitions kicked.

Benzol has had several meanings in different countries and time periods. I believe Neil is closest for this use - in the early 1900's, it was a
coal-tar distillate composed of aromatic hydrocarbons, mostly benzene with some toluene and xylenes. It was used as an industrial solvent, or could be
mixed with petrol as a fuel. Nice high octane number, but burns with a black smoky flame.
In Germany and Russia, I believe it actually means benzene, while the word "benzin" means gasoline.
I actually haven't seen it used to mean phenol in anything technical, but I see enough definitions that point to phenol that I can't say for sure that
it wasn't.

The concept that 35 tons of benzol blew up a ship which also coincidentally contained 2510 tons of high explosives is rather unlikely.
Ten minutes after the ships collided it caught fire and burned for 25 minutes. In that time period the most common form of steamship used coal burning
boilers for power. This guarantees a source of ignition.
With perfect 20/20 hindsight they should have used the time to lower the lifeboats and head away from the craft.

Benzol is just German for benzene.
One shouldn't accept or resort to the mutilation of science to appease the mentally impaired.

And it's also an older British term for phenol...(benz)ene-alcoh(ol).

Ya need to do a re-read on your history books. The ships struck, this left the bows locked and ruptured barrels off benzene which were piled on the
deck of the munitions ship. The emo reversed pulling free not knowing about the munition. The banners for a ship carrying munitions was not visible on
the mont blanc. As the ships seperated the benzene ignited. The surrounding barrels boiled burst and ignited. At this point the french crew had jumped
ship and rowed to shore. The burning fuel on the deck made the fire unfightable and spread the flames below deck to the picric acid which eventually
did what it does best. The crew of the munitions ship were unharmed.

Yes I didn't read all about it. So we have a common inflammable liquid which caught fire and involved the cargo. I'm glad the crew got off safely.

Ironic they got off, since it was the compounded stupidity of them that got the city blown up.
The ship was loaded illegally, had the munitions and fuel stored illegally, carried no outwards warning as to the cargo and invented their own rules
of the road with regards to right of ways in the harbour.
