Making Phenolphthalein (a common pH indicator)

In this video, phenolphthalein is synthesized by the condensation of phenol and phthalic anhydride. The phenolphthalein is separated from starting materials by several washing steps. In theory you can also just extract the phenolphthalein from the reaction mixture using NaOH solution. This will pull out the phenolphthalein as well as the phenol. Then when the phenolphthalein is crashed out, the phenol should stay in solution. Then recrystallize. Much faster method. ------------------------------------------------------------------------------- Merch - https://nilered.tv/store ------------------------------------------------------------------------------- ■ NileRed is now available on Nebula! https://go.nebula.tv/nilered (when signing up with this link, a portion of your membership directly supports the channel) Join the community: Patreon -   / nilered   Discord -   / discord   NileRed Newsletter - https://nile.red/home#newsletter You can also find me here: Facebook -   / nilered2   Instagram -   / nile.red   Twitter -   / nilered2   Nile talks about lab safety:    • Chemistry is dangerous.
