well i have finaly got around to making another batch of
ketone. did the bisulfite test and yep we got ketone.
things I have noticed are that my ketone this time was
green and not a light yellow.
mag stirring is essentual it not only saves you a heap of
energy in not having to shake the fuck out of your solution
but trust me it saves glass.
I have been through so many rb flasks condensors ect becouse
of overhead stiring or manual shaking.
never again.
I have also come to the conclustion that NaOH sucks arse bad
I have done veriose isomerizations with NaOH and KOH
now and this is what I have found.
NaOH + CaO (CaO was CaOH dried in a test tube at 1000 C)
in isopropyl alcohol:
this is probably the best way to do an iso with NaOH
I got a 60% yeild and found you didont have to dry
your alcohol just make sure your CaO is not CaOH
no alcohole:
no good the CaOH eats all of the safrole and you have a
bitch of a job getting it back.
no CaO
in alcohol:
i got no iso from this it was just to hard to control
water content.
no alcohol under vacuum for 12 hours:
I got a 20% yeild not worth it for me.
KOH:
first try 90% yeild did it under vacuum with mag stirrer
on never use NaOH again trust me the chem supplier
is not going to suspect a thing if you ring them up
and order KOH just tell them you drying grapes into
raisens
