EtOAc using H3PO4
As I do not have glacial acetic acid nor sulfuric acid, I am trying to find ways to make EtOAc using alternative routes.
Will concentrated H3PO4, NaOAc, and EtOH make EtOAc in decent yields? The goal is to convert NaOAc to HOAc with H3PO4 and that will react with EtOH
to form EtOAc. I would probably need to reflux this.

i also interested in "alternative" ways , but with other chemicals..
using the acetic acid from vinegar and Cu catalyst for make my acetaldehyde (and bubbling this in formaldehyde), but i'm not sure which this works
well... i tried search in this forum, and find some few experiments using this. this also really works?? feasible?? thanks.. (really sorry because i
think which this isn't much "proper" to ask in this thread ...,eh?)
-----------------
about the H3PO4 (instead of H2SO4) you H3PO4 is froom pool supplier?, this can work great in your synth even with the propertie which max. conc. is
around 85-90%???
thanks

Um, my H3PO4 is gonna be from decomposing ammonium dihydrogen phosphate (Im not allowed to have any strong acids...parents). Its going to be quite
concentrated hopefully.

then can works, although your product can contain a lot of water due the H3PO4, even be a "fixed acid" can allow some water to vaporize together with
this EtOAc...
-----
i will search in forum, also if has one easy method for make glacial from vinegar..
maybe this can be done simple made (or ordering from any place) calcium acetate, bring to dryness and reacting/destill with conc. H2SO4(low pressure
should be a good thing..) to give glacial... and this reacting with EtOH, to make EtOAc... unfortunatelly, destill the acetic acid can be a dangerous
thing(especially if make a room pressure) because has risks of fire,explosion,etc..and also as you mentioned ,

this is same which happen to me sometimes when my mom is furious!
