How to Extract Red Phosphorus from Match Striker Pads

TL;DR

To extract red phosphorus from match striker pads, dampen the pad with a wet paper towel, then scrape off the phosphorus carefully to avoid sogginess. For small-scale experiments, this method yields about 0.03 grams of red phosphorus per matchbox, making it suitable for occasional use in organic chemistry. A drying step with acetone can help purify the extracted phosphorus further.

Transcript

Red phosphorus is commonly used on match striker pads and it's pretty much the only source of elemental phosphorus for the average person. Although it's a readily available source there's really not much phosphorus on each striker pad and to get a decent amount it takes a lot of time. I think it's only worth it if the red phosphorus is needed in ... Read More

Key Insights

• 😪 Red phosphorus is commonly found on match striker pads and is an accessible source of elemental phosphorus.
• ♠️ Extracting red phosphorus from match striker pads is time-consuming and better suited for small-scale experiments.
• 😪 Red phosphorus is useful in organic chemistry, such as in the production of methyl iodide.
• 👨‍🦳 Conversion of red phosphorus to white phosphorus allows for different reactions.
• 💦 The extraction method described in the video may not work as effectively for all match brands.
• 😪 Timing is crucial to obtain the right consistency for scraping off red phosphorus.
• 📪 Acetone can be used to wash away any residue from the match box before drying the red phosphorus.

Questions & Answers

Q: How can red phosphorus be extracted from match striker pads?

The easiest method is to dab the match box with a wet paper towel and then scrape off the red phosphorus using a spatula. Timing is crucial to ensure the right consistency for scraping.

Q: Can this extraction method be used for all match brands?

While it works well for the match boxes demonstrated in the video, it may not be as effective for other brands. Trying out different methods and solvents is recommended.

Q: What can be done to remove any leftover glue or water after scraping?

Spraying a little bit of acetone and washing the match box can help remove any glue or water residue. Pouring off the acetone afterwards will leave behind the wet red phosphorus.

Q: How can the extracted red phosphorus be dried?

Scraping the wet red phosphorus onto a piece of paper and allowing the acetone to evaporate will result in a more powdery consistency. Leaving it for a few hours will ensure thorough drying.

Summary & Key Takeaways

• Red phosphorus is commonly found in match striker pads and is the main source of elemental phosphorus for the average person.

• Extracting red phosphorus from match striker pads takes a significant amount of time and dedication to obtain a decent amount.

• Red phosphorus is useful in organic chemistry, such as in the production of methyl iodide, and can be further converted to white phosphorus for different reactions.
