added other 20% mixed for a hour let setting for 15 mins then drained glycerol
did the 27/3 test but came out alittle foggy and there was a small ammount of oil on bottom so tryed to reprocess
adding 3.5L Meth and 100g KOH mixed for 1 hour and let settle for 30 mins and drained glycerol but 27/3 test was basically the same so reprocessed again the same way

At what temperature did you perform the 27/3?
Can you up scale the test to something larger so that the dropout can be measured?
-
Was the oil dewatered and dried before the reaction ?
Oh and wellcom to the wiki and wiki forum.

your source oil must be good to come back at a value of 4. so you used a total of 1100grs of koh over both stages?
Thats 7gr per litre plus 4 grs per ltr tit value total 11grs per ltr over 2 stages. and welcome
