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 ------------------------------------------------------------------------------- Join the community: Patreon - https://www.patreon.com/nilered Discord - https://discord.com/invite/3BT6UHf NileRed Newsletter - https://nile.red/home#newsletter You can also find me here: Facebook - https://m.facebook.com/NileRed2 Instagram - https://m.instagram.com/nile.red Twitter - https://mobile.twitter.com/NileRed2 Nile talks about lab safety: https://youtu.be/ftACSEJ6DZA
