[edit]Cumene is not a common name for isopropylbenzene
I started undergrad as a chemical engineer in 1989, and with the exception of a 3 year return to graduate school, I have been working in the field since graduating. Up until reading this on wikipedia today, I have never even heard of the word cumene. Everyone refers to this chemical as isopropylbenzene or, less commonly, methylethylbenzene. I don't think anyone actually refers to it as cumene anymore, or if they do, they are in a distinct minority.

Vapor pressure
[edit]The US EPA reports cumene vapor pressure as 4.5 mmHg (0.6 kPa) at 25 C. This is different than the value in the article which is based on the NIOSH value of 8mmHg at 20 C. Any thoughts on resolving this discrepancy?

- Another source confirming the US EPA value is "Daubert, T.E., R.P. Danner. Physical and Thermodynamic Properties of Pure Chemicals Data Compilation. Washington, D.C.: Taylor and Francis, 1989". There are other sources with the same value.Sandcherry (talk) 21:01, 5 July 2022 (UTC)
Source of the name?
[edit]Cuminaldehyde, major component of the aroma of the spice cumin, can be synthesized by formylation of cumene. So I wonder if cumene was first prepared by deformylation of cuminaldehyde, or if the name was adopted after the structural similarity was recognized. Eaberry (talk) 04:35, 15 June 2023 (UTC)
