Last week there was a huge fire in french chemical factory Lubrizol, we now know the main products that burnt, to simplify the discussion I extracted a few compounds:
isobutyl and isobutene polysulfide 500 tons,
dithiophosphoric acid and corresponding zinc salt (R = isopropyl) 200 tons,
various hydrocarbons (mainly mineral oil) 2000 tons
as well as calcium sulfonate and calcium salt of methylphenol sulfide (100 tons), amides/esters of phosphoric acid, polymers, aromatic amines & alcohols, various reaction products of $\ce{P2S5}$ with isopropanol 400 tons
What kind of sulfur compounds should we expect to be emitted from pyrolysis and combustion of such organosulfur compounds?
Note the authorities claim the smoke analysis didn't show any $\ce{H2S}$ and that the $\ce{SO2}$ level wasn't higher than everyday measurements in cities.
There is a paper on the pyrolysis of polyethylenesulfide showing cyclization leads to a bunch of products, I wonder if it is applicable here (also I would like to know why no $\ce{H2S}$ is formed?)
