Well written except for one paragraph
[edit]This seems to me a well-written and clear short article, with a very good example in the first section. However I find the second section more confusing, especially the first paragraph "In the PTC process, the same concept applies, that of transporting ionic species from one phase to another. The difference lies in the fact that with PTC, a chemical reaction is promoted and nothing is “isolated” or “purified" during the reaction process. Instead, PTC promotes organic synthesis reactions by transferring mutually insoluble reactants into a common phase."
Are there really two different types of process being compared here? I would have thought that PT catalysis is just a reaction using a PT catalyst as defined in the previous section. Can someone explain this "difference" more clearly? If not, perhaps this paragraph should be deleted. Other opinions please? Dirac66 (talk) 02:27, 21 November 2007 (UTC)

Major edit proposed
[edit]@Dirac66 and Klbrain: Six refs (of 15) are to H. Nur. The refs are all primary, none to reviews. These journals are low ranked mostly. All of the colorful graphics are by the same editor (HadiNur). Almost all of that editor's (assuming it is one person) is focused on a particular section. We see this kind of pattern occasionally in Wikipedia where a modestly active article is basically taken over by some specialist in the field, perhaps hoping to promote their work. Who knows really.
I suggest that the entire Nur section be removed as a probable distortion of the reality of the field (WP:UNDUE). Am contacting editors who have previously contributed.--Smokefoot (talk) 23:34, 25 February 2025 (UTC)
- The section "Design of phase-boundary catalyst" is clearly too long and detailed with too many examples by the same author. But I think we should keep a shorter version to mention phase-boundary catalyst with an example or two, and note the difference between the two terms phase-transfer catalyst and phase-boundary catalyst. As a first specific suggestion, I would say keep paragraph 3 of the intro on PBC with perhaps two of the five examples, and delete the detailed recipes in the longer section "Design of phase-boundary catalyst".
