Acetone From Iso-Proponyl Alcohol

Acid Test - 8-1-2004 at 11:21

I have posted this in one of the threads and
no one wants to respond.
CH3-CH(OH)-CH3+HCl =(CH3)2CO+2H20

Is this correct for those who keep hassling
me about a balanced equation?

Next I had some KOH in a film canister(with
the pop on lid,not perfolated lining lid)
and it spilled on top of my fridge in my
room.It got some dust impurities on it.
Will the air and these particles effect this.
I think it happened about 3 hrs ago

Quick bit of Organic Chem review:

- Oxidation of a primary alcohol will form an Aldehyde
-Oxidation of a secondary alcohol will form a Ketone

This equation still is not balanced. On the right side, you have 3 O atoms while on the left, you have just 1. Also, on the left, you have a Cl, but it is not on the right. Where did it go?

It would seem more likely that HCl would react with Isopropanol as such:

H3C-CHOH-CH3 + HCl --> H3C-CHCl-CH3 + H2O

To form 2-Chloropropane. Just speculation, not positive on this. If you're looking to form Acetone, you will need to react Isopropanol with some Oxidizer. NaOCl may work, but you'll probably want something stronger, like Potassium Dichromate.

I would definately go with the dichromate or a permangate solution to do the oxidizing, with NaOCl you're going to have a basic soultion with free chlorine, perfect for a haloform reaction which would oxidize the acetone formed to acetic acid.

Actually if you react H2O2 with the acetone
that should yield acetic acid or
anhydrous acetal

You might get some Acetic Acid or anhydrous acetal(dehyde?). My guess would be that you would also get a fair amount of Acetone Peroxide though.

Does acetal refer to acetaldehyde, or the plastic. It's also used to refer to Diethyl acetaldehyde. Is it one of these or an I way off?

Is it just me, or does Purple Haze's post look remarkably similar to the former Acid Test? The words going halfway accross the screen is a fairly good give away. Might want to keep an eye on him/her. Unless of course you IP banned him, then we shouldn't have much to worry about.

[Edit] Ok, after comparing their profiles I am 99% sure they are the same person. Have a look for your self. Its not a coincidence they have the same birthday, e-mail, and from a close proximity to each other.

I think the drug references look fishy too, not to mention the questionable grasp of chemistry.
Acetals are the reaction products of alcohols and aldehydes.
RCH (OR)2
Hardly matters; you certainly won't get them from IPA and HCl.

Off topic but, yeah, they're definately the same person....
