SALICYLIC ACID + ACETIC ANHYDRIDE is AN ESTERIFICATION REACTION! AN ESTERIFICATION REACTION!


just thought you ought to know...  :buck2:

Thank you for that insight (I will assume you have placed this here for serious reasons, such as to serve others as a reminder from a personal mistake)

However, this is leaning towards trolling. Future reminders like shall stay in this thread, and this thread will remain spam-free.

lol I'm not sure how such a thread could work. I.e. I could say a hydroxyl group has formula -OH. That's a reminder too isn't it? Just saying it's pretty vulnerable to chem-trolling.

That is ethanoic acid +  ethanoic acid to give water and ethanoic anhydride.

Formation of esters from carboxyl and hydroxyl is a condensation reaction.

Same goes for formation of amides from amine and carboxyl, and formation of ethers from hydroxyl and hydroxyl, and any other linkages that has water as a product.

Also the reaction between an acid chloride (COCl) and an amino group is a condensation reaciton that produces HCl (according to Nelson this is still termed condensation).

Yes. Loss of small molecules, these include water, HCl, methanol and acetic acid, etc. The latter are encountered in higher organic chemistry.

[Though I am not sure if Salicylic acid + Acetic Anhydride can be classed as a condensation reaction]

um.m... so i conclude that it would be more safe to classify the reaction between acetyl anhydride and salicylic acid as esterification? lol    ::)
