Glyc amount using ASM

[RichardP]

Just a quick question for those using ASM regarding the amount of glyc that is produced compared with the amount when using NaOH or KoH.

I do 160 - 170 liter batches, and with NaOH used to get around the same volume of glyc out as the methoxide going in, around 26 liters.

Now with ASM I'm getting around 15 liters or so out with a total of 25liters meth & ASM going in.
The finished bio amount is going up by that 10 liter difference too.

Anyone else getting a similar thing?

Haven't quantified it yet, I been concentrating on not making soap, but the last batch that worked OK, defiantly showed a significant reduction in glycerine.

[Head Womble]

Julian, are you still doing a titration two stage or have you gone over to titless ?

[Julian]

The last couple have been no titration.  But I find it more hassle the normal two stage and I still think that a 3/27 (or derivative there of) needs more time to drop than the process sensibly allows.

I've only done one batch so far, but yes, I'm seeing that too.

I was the first to stick my head above the parapet ref. a greater out put of bio than wvo in.

I do 100ltr batches and only need one 20ltr cubies for two batches worth of glyc, btw I'm not demething the Glyc.

Others using ASM have also noticed the difference.

This is really interesting the way changes in making the Bio are panning out. My batch using acetone had the same sort of reduction in Glyc that you have experienced with ASM,  this was with KoH though. I had about 19 litre's from a 180 batch.

[jgs600]

yes i agree too, also on my last batch i made ui used less meths too than ive ever used, and my soap levels have deffo been lowered, as i need to water wash way less than ever now to get a clear 50/50 pass

[db]

My 1st batch with ASM deffo produced less soap, approx 8 litres less. I forgot to measure the final volume of bio though, but I'm expecting it to increase.

[BassAddict]

I've noticed the same too - much less glyc and much less meth used too. 180 litre batch and only 25 litres used in total (plus ASM) Stage 1 = 20 Litres meth + 3.6 Litres ASM. 1ml drop out. Added 360ml ASM to the other 5 litres and got a perfect pass with little soap and 30 litres of glyc rather than 40 - 45 I get.

How can it possibly make more bio than WVO in?

Seems impossible but one of the chemist's will come in with an explanation I'm sure, it was explained to me but didn't stick enough to repeat it with any accuracy.  Your Glyc amounts do seem a tad high still though for some reason.

Today I received a nice suprise, 20L of ASM that I wasn't expecting (a very nice and unexpected suprise).
So I'll be using it on my next batch, hopefully I'll replicate these findings.

I now need to do some reading up on use and storage of this magical stuff.

He said you'ld be surprised.

Storage:

Shelf life of ASM is quoted as 12 months from delivery if kept dry and in original packaging. Storage temperature should not exceed 30°C, and at temperatures below 10°C the active ingredient may start to precipitate. Warming, combined with agitation will help re-dissolve the active ingredient.

Crystallisation temperatures of ASM solutions:

    25% ... -2°C
    28% ... 0°C
    30% ... 5°C

Is there a calculator for It. I've looked but can't find one.

It's safe to say Carl will be getting a top up whenever he needs one for a while yet.

All the calculations are here Mark. It pretty much covers all methods. I use a base of 4 for stage 1 ([4x 150] x 5) and 5  for stage 2 ([5x % of unreacted] x 5) on a two stage no tit.
