ok so my oil titrates to 10
(not including the 5 as a start figure)

so I mix up a test acid treat batch:

1L dry oil
100ML methanol
1ML 95% H2SO4

heated to oil to 140F

added 1ML acid to 100ML methanol
(did not get "violent boiling" like I thought i was supposed to)

when oil cooled to 110F
I added the acid/meth
(did get some "boiling" here)

held at about 100F and mixed for 4 hours
checking titration every hour

at hour #1 titration was 15
and stayed there until hour #4

stopped mixing and heat
let sit overnight (an additional 6 hours)
titration was again 15

let sit all day
(total time = 19 hours)
titration is now at 14

there was also a very thin lighter colorerd layer kinda frothy looking

I did remix before titration test.


did I not add enough acid ?
is my acid too weak ?
can I add additional acid to make up for that ?

would that be 10 NaOH or KOH?

1ML 95% H2SO4

heated to oil to 140F

added 1ML acid to 100ML methanol
(did not get "violent boiling" like I thought i was supposed to)
if KOH, 10-3=7*0.2=1.4ml of acid/liter -> you didn't use enough acid

when oil cooled to 110F
I added the acid/meth
(did get some "boiling" here)
why wait until oil is at 110F. i use 140-150 F

held at about 100F and mixed for 4 hours
checking titration every hour
for every 10C drop the time doubles
at hour #1 titration was 15
and stayed there until hour #4

stopped mixing and heat
let sit overnight (an additional 6 hours)
titration was again 15
why stop. i sometimes mix form 24 hrs. non stop

the only problem with Acid/base that I have ever run into is something else besides FFA causing a high acid reading...I have had this 2 times since starting to use acid/base
sorry I don't have an answer in this case, but your case looks like to was too cold and not enough acid. so try reheating( a vent should be open for expansion(maybe safety)) then add 0.4ml of acid(per liter) to 1 gallon of methanol(total) to the mix. mix for hours checking titration every hour if you can. if the titration rises...darn!!! looks like you had a false high reading..otherwise it should fall.


good luck

the original titration figure I gave was incorrect..
it was 15 ( not including the base 5)
and these figures were using NaOH

I have added another 1ML of acid, and a bit more meth as I dont know how much has evaped..
(the container has been closed but not sealed )

so its back on the heat and mixing
with 2ML acid per 1L oil

after 1.5 hours, titration is now down to 13.5..

so it never "went up"
I just reported the wrong value by mistake.

so I have lost 1 point and a half so far..

cold = longer processing correct ?
and
no mixing = longer processing ?


"wait and titrate" my new pastime .. Smile

oh ..
and dkenny

thanks for your input, and for all of your past input..

before I decided to attempt this acid stuff,
I read just about every post on this acid method topic, and you appear to be one of the key people out there forging ahead with this process and bringing valuable real world data to the table, and I for one appreciate it.

thanks..
