How to Transform Paint Thinner into Cherry Soda

TL;DR

To transform paint thinner into cherry soda, extract toluene and convert it to benzaldehyde using the Étard reaction with chromyl chloride. After several attempts at purification, the YouTuber successfully produces pure benzaldehyde, which is then used to create cherry soda that tastes surprisingly similar to the real thing.

This video has been sponsored by Opera. A few years ago I turned plastic gloves into grape soda and now I want to try turning paint thinner into cherry soda. This is something that I've been wanting to try for a while and at first it might sound like it makes no sense. Especially because of how horrible tasting and toxic paint thinner is. However j...

Key Insights

• 🛩️ Toluene and benzaldehyde share similar chemical structures, with only a small difference present in their compositions, which makes it possible to convert one into the other.
• 🤔 The process of converting paint thinner into cherry soda requires careful purification of the paint thinner to remove impurities and the use of complex chemical reactions.
• ❓ The Étard reaction is an effective method to create the Étard complex, which can be further decomposed to obtain benzaldehyde.
• 👍 Carbon tetrachloride proved to be a more suitable solvent for the reaction compared to other solvents used in earlier attempts.
• 💁 The purification of benzaldehyde involved multiple steps, including filtration, washing, drying, and distillation, to obtain a pure form of the compound.
• 🌸 The final cherry soda made from the obtained benzaldehyde tasted remarkably close to regular cherry soda, demonstrating the success of the experiment.
• 🙈 Persistence and adjustments are crucial in overcoming challenges during scientific experiments, as seen in the YouTuber's multiple attempts to achieve the desired result.

Questions & Answers

Q: How does toluene in paint thinner resemble benzaldehyde used in cherry flavor?

Toluene and benzaldehyde share similarity in their chemical structures, with only a small difference present. Benzaldehyde, used in cherry flavoring, has an additional component that distinguishes it from toluene.

Q: Why did the paint thinner need to be purified?

While the paint thinner claimed to be toluene-based, there was a concern that it might contain impurities or sulfuric acid. The toluene was tested for impurities by mixing it with the mixture of sulfuric acid and isatin and ensuring no blue color appeared, indicating the absence of sulfur impurities.

Q: Why did the YouTuber choose the Étard reaction method?

Among several methods, the Étard reaction was chosen for its simplicity and the availability of chromyl chloride, which is a key chemical used in the reaction.

Q: What challenges did the YouTuber encounter during the experiment?

The initial attempts did not yield pure benzaldehyde, and the uses of various solvents and purification processes were required to achieve the desired result. Additionally, there was a risk of explosion during the reactions and the need for caution to handle toxic and volatile chemicals.

Q: How was the benzaldehyde isolated and purified from the Étard complex?

After isolating the Étard complex, it was decomposed using a sodium sulfite solution. The resulting mixture was then filtered, washed with solvents, and dried using drying agents to obtain a crude version of benzaldehyde. Further purification was achieved through distillation and additional filtration.

Summary & Key Takeaways

• The YouTuber sets out to convert paint thinner, which contains toluene, into cherry flavor, as toluene is similar to the chemical benzaldehyde used in cherry flavoring.

• After obtaining toluene-based paint thinner and purifying it, the YouTuber attempts the Étard reaction using chromyl chloride and toluene to create the Étard complex.

• The Étard complex is isolated and later decomposed to obtain benzaldehyde. However, the first attempt does not yield pure benzaldehyde.

• The YouTuber makes adjustments, including using carbon tetrachloride as a solvent and isolating the Étard complex. After multiple attempts, they successfully obtain pure benzaldehyde.

• The pure benzaldehyde is then used to create cherry soda, which surprisingly tastes similar to regular cherry soda.
