This is to experiment with variations in the classic Blue Bottle demonstration. I found a nice paper (thanks to Corrosive Joeseph for the full text)
that I'd like to replicate (attached here for reference). I need either these spcific solutions or the solid dyes, probably only a gram of each.
The paper also uses Benzoin (CAS# 119-53-9) as the reductant; I'd like to try this with the standard dextrose first, but if that doesn't work I'd need
a source for benzoin as well.
Anyone have any suppliers that have these dyes? Or does anyone have a tiny amount they'd be willing to sell me?
Ebay UK has three of your listed dyes in addition to Methylene blue and Indigo carmine.
Yes that is an interesting paper.Sulaiman - 12-8-2019 at 21:49
Methylene blue plus glucose (dextrose) is interesting, I had to demonstrate to all of my family - not impressed.
I first came across the reaction after a little research
because I bought six old Thunberg tubes via eBay,
- they were weird, and most importantly, cheap.
I also liked to observe the surface layer, just a thin layer of blue where oxygen can diffuse into the glucose solution.Ubya - 13-8-2019 at 00:13
benzoin can be easly made by the condensation of benzaldehyde using thiamine (vitamin B1) as the catalyst (instead of HCN)MrHomeScientist - 26-8-2019 at 08:03
Thanks for Carbon8 for the safranine! If anyone knows of any others from my list, let me know. I couldn't find any of them on eBay UK
back when wg48temp9 posted, for some reason.wg48temp9 - 26-8-2019 at 10:05

In case I am going mad I checked again and found only two this time from your list but I did not spend much time on it. One trick is search with
alternative names for them. See the links below
