Andrew,
Now all of this rests upon me getting my alcohols right, so search, at
the top of the page, for isopropyl at this site, www.rsaustralia.com.
This gives a range of container sizes. There is also an MSDS at:
http://docs-asia.electrocomponents.com/webdocs/0065/0900766b80065e94.pdf
It seems that hydroponics stores carry very pure isopropyl alcohol as well.
I seem to remember a price of about $40 for one US gallon for the
99.5%stuff, which is similar to the price you found though.

Guys;
The titration solution is water anyways so what difference is 10% water
gonna make in the IPA? The water is always a problem cuz it makes the
oil want to drop out and unless you've got good agitation I wonder how
accurate the titration really is. I've been wondering what about using
?
Actually, I think anhydrous IPA would be less important.

I agree with Keith that it is best to
1. Use the best quality chemicals and measure accurately.
(This will always be important, but absolutely crucial when doing small,
initial test batches.)
2. Do not attempt to use WVO (and titration) until you have

try going to a hydroponic supply store, they have the stuff.

Hi
I seem to be having trouble sourcing
Isopropyl Alcohol for titration, I've tried pharmacist in my area (kent UK) but none seem to have
it. Can anything else be used or does anyone know a likely supplier.

Dunno about the UK but we've 55 gallons on hand if anyone in the DC area
wants it...you haul.

I just checked the archives to make sure that denatured alcohol is
suitable for titration and it appears to be. Anyway I used to buy
quarts of 99% isopropyl alcohol at the local hardware store to use as
a solvent to clean video heads. If this is the same stuff, I suggest
you look in the paint
find a chemical place
you need 99% stuff
look around
maybe try a jantroial place they would be able to point you in the right
direction

I have been able to find what is called isopropyl alcohol 70% which
does not contain anything BUT isopropyl and some water.(another
brand had camfor in it and I already figured that that would not do,
genius huh
the guy in savanna ga
he showed me the titration test
used a alcohol like everclear
he made a batch in blender ( 1 liter. blender batch)
tested i density was 8.5
ph was 5 i think
i live in the tampa bay area i know someone in the cataplier org.
i'm going to get a
x-charset ISO-8859-1That was me. I BLEW it last Thursday when I (nor my
chemist partner!!)
didn't notice the scale was set on ounces instead of grams. Made some
spiffy soap allrighty though. Am going to run the titration test again
either Thursday or Friday on 70%, 91%, and 100% stuff on
get some everclear at liquor store
99.7%
trust me

everclear when I used to buy the stuff was 95% ( an azeotrope). To
get production of greater than 95% requires a process which I have never
seen employed for alcohol made for consumption.

Hi,
A little while back there was talk about 70% Isopropyl Alcohol verses 95%. I
didn't see the answer as to if the 70% would work or not. I haven't been
able to find anything more than the 70% in Rubbing alcohol. I want to do a
Titration and need to know if it will work or not.
Thanks
