replies: text: No, what we tend to do is provide a couple of high quality recent references. We do not need more than 3. The point is not controversial. Doc James (talk · contribs · email) 16:18, 11 June 2017 (UTC)

thread_title: "composed primarily of volatile hydrocarbons."

message: The article currently seems to treat coal tar largely as a pharmaceutical, with some secondary nods to uses as a sealant or a fuel, and a brief mention of synthetic dyes.
But coal tar was the genesis of organic chemical synthesis on an industrial scale.  It was the feedstock for what would become the petrochemical industry before people realized that petroleum was more cost effective.  Not just dyes but synthetic pharmaceuticals (very different from the pharma uses currently described, which are mostly about using refined coal tar itself as a drug rather than molecules synthesized from it) — especially sulfa drugs.  And plastics -- bakelite for example.  Anything you'd make from phenol or aniline.
These days, of course, the synthetic organic chemical industry uses mainly petroleum, but it got its start with coal tar.  It seems like a pretty important aspect of the topic to discuss in this article. --Trovatore (talk) 09:03, 20 January 2022 (UTC)
