Discussion Overview

The discussion centers around the feasibility and safety of creating a glow-in-the-dark mist using luminol, particularly in the context of its chemical properties and potential hazards. Participants explore the chemistry involved, safety concerns, and practical applications of luminol in a mist form.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant inquires about the nature of alkaline solutions and auxiliary oxidants, expressing a desire to create a stable fluorescent compound that can glow when dispersed in the air.
  • Another participant warns against the hazards of vaporizing luminol, emphasizing the risks associated with inhaling chemicals that produce reactive free radicals.
  • A different participant challenges the severity of safety warnings, suggesting that such warnings can be exaggerated and comparing luminol's use to other chemicals commonly vaporized in fireworks.
  • Concerns are raised about the differences between a coarse spray and an aerosol, highlighting the potential dangers of inhaling reactive chemicals.
  • Participants discuss the practical use of luminol in forensic applications, noting that it is used in limited quantities due to health risks and mentioning potential regulatory actions against its use.

Areas of Agreement / Disagreement

Participants express differing views on the safety of using luminol in a vaporized form. While some emphasize the hazards and advocate for caution, others downplay the risks and argue that similar chemicals are used without issue. The discussion remains unresolved regarding the safety and practicality of the proposed glow-in-the-dark mist.

Contextual Notes

Participants reference Material Safety Data Sheets (MSDS) to discuss the health effects of luminol and other chemicals, indicating a reliance on specific definitions and interpretations of safety information. There is also mention of regulatory considerations that may affect the use of luminol.

"Luminol in an alkaline solution with hydrogen peroxide in the presence of iron or copper[1], or an auxiliary oxidant[2], produces chemiluminescence."

1. What's an alkaline solution?
2. What's an auxiliary oxidant? (another source of oxygen? Like...air?

I'm trying to find a (fluorescent compound?) that can glow while thrown in the air (to create glow rain/mist or something like that). However, it needs to be stable so as to now waste it's glow before I'm ready for it to start glowing in the air...

I couldn't find any information on the vaporization point of luminol (I was thinking of spraying luminol gas with hydrogen peroxide gas in the air or something).

If you can't tell already I have limited knowledge of chemistry (I learn fast though) and just googling some promising ideas for a project I'm working on which is to create a glow in the dark mist so to speak.

I can't imagine anything more hazardous than to vaporize a compound that converts free radicals into light and stabilizes those free radicals long enough for the glow to persist. It's a bad idea. Bad juju! Run Will Robinson! Run!

My favorite part of the MSDS is the Potential Acute Health Effects section...

Very hazardous in case of eye contact (irritant) of (sic) ingestion.

Nuff said.

Eh who follows warnings, they can be largely over exagerrated...You call poison control every time you accidently shallow some toothpaste? Every time you get bleach on your skin?

MSDS says the same thing about potassium perchlorate and plenty of other chemicals used in readily available fireworks that get vaporized all the time. In fact, the way luminol is even used is to mix it in a bottle with hydrogen peroxide and other stuff and spray it around. No difference than it being a vapour than a gas.

A coarse spray and a fog or aerosol are completely different.

Hey, if you want to risk breathing in a chemical that forms reactive triplet ions upon exposure to blood, knock yourself out. If you do this and expose others, expect real troubles...

The MSDS for http://www.fsafood.com/msds/vault/002/002477.pdf" toothpaste:
INGESTION: May be harmful if swallowed in large quantities.

I used Google to see what Luminol is used for, and you are right, it is used in a spray form by forensics teams for crime scenes. In Britain though, they use it in very limited quantities due to the health risks. In fact, there is some talk of banning it.

Like chemisttree said, be very careful if you are going to use this stuff with people around.
