Hi Charles
Yes, it makes the head hurt.

Hi all
I am about to start using KOH as a catalyst for my single-stage base
catalysed reaction, so, like a dutiful good boy, I read the
instruction at JtF to find out what to do. My KOH
Keith, Charles:
Doesn't it also make sense not
to adjust for purity in making the lye solution? I use a .1% solution,
no matter what the catalyst. I adjust the starting number for purity
(in this case yielding 5.775), but then allow the titration to help me
avoid math mistakes.
In this case,
Hello Sean
You're right, it amounts to the same thing.
I got it all figured out but didn't spot that the adjusted figures
cancel each other out.
Reason being we never do it that way, we use 0.1% NaOH solution and
convert the total result for 85% KOH.
I'm not sorry I did that though. I found
To everyone that sent me information on testing the differences in KOH.
As you recall I got a 50 # bag for $10 at a blue light special at my
local chemical supplier. I did the titration against lab grade near
absolute and found after 2 separate titration about a 6% degrade in
quality. Using

Hello folks
For those with experience in the.pricing out and purchasing of KOH,
is it common place for one chemical company(Univar) to be selling 90%
pure flake @ $2.78 per kg, and the next company(Anachemia) to be selling
85% pure pellets(ACS certified) @ $28.50 per kg?
What prices
Marc,
Purity can vary. But price shouldn't be but a few pennies or a dollar or
so difference per pound unless you're buying lab grade.
One reason for the price difference between pellets and flake may be
that the pellets are intentionally formed, requiring several extra steps
in comparison to

The old timers here may have better info than me. You should look for a
local source, shipping will be the major cost if you shop well. Try this site:

In the trade, the commodity you want is called caustic potash. The 85%
material should be very good for your use.

KOH is not as strong as NaOH -- use 1.4 times as much KOH (actually
1.4025 times). Titration is the same, just use a 0.1% KOH solution

Dear Mohamed
KOH or NaOH:
NaOH is more commonly used, because it's cheaper and more easily
available. Or so it's said. Here in Japan it's the same price, but
whatever the price you have to use more, how much more depends on the
concentration (not as concentrated as NaOH). See:
More about lye
Dear all
could u tell me the difference in using any of these
catalysts
Does it affect the production rate??? Or the
quality/quantity ??? or the over all cost ??
What about the use of lipase which is a biological
catalyst ???
How important is it to use the right catalyst
Please advice

This has to do with whether to use NaOH or KOH as your
catalyst-of-choice. That's generally said to be KOH, because you end
up with a useful potassium fertilizer as a by-product, whereas with
NaOH you're left with a useless salt. But it's not that simple. Sorry
to say.
