>I've read a patent
Which one? Here's the
source article for my experiment
(

>reflux at 115C,
not really reflux, just near boiling/barely boiling - cause when you shake it it's gonna boil violently.
>until toluene reacts (apx how long? couple hours?)
yep. You'll see when it stops.
>add 2.5g water down the condenser
Whut???
>filter off ~11.3g toluene-4-sulfonic acid
no way.
>Will the H2SO4 eat through standard filter paper?
it definitely will, in no time
>Is there anything I can use to wash the crystals?
I dunno. If you do everything like in the article, they'll bee already quite pure.
>Btw, will some MeOH in the toluene form the methylating ester that you desired?
Seemingly, no, as SWIM had no luck doing it w/methanol. Ah, everything may bee - like he just did smth wrong or had wet methanol - SWIM was unforgivingly careless at the time, now life has taught him some precision
