…I think my LABSA is not so pure as I thought…@Chemist77 do you know how long did you mix LABSA with NaOH to get pH8?

Thank you @Gunther. Yes, now I am searching for the best proportion to get neutralized product. I am also checking how long my neutralitzaion will take.

My LABSA is 95% and I dilute it into 30%. Than I am adding 30% NaOH and I have delaminate salt. Tomorrow I will mix it as @Chemist77 wrote

@Chemist I will mix it. Could you tell me did you mix 96% LABSA with diluted NaOH (eg. 30 %)?

@Chemist thanks, do you think that the Sodium Lauryl Benzene sulfonate (LABSA Sodium Salt) is on the bottom or on the top of this beaker?

I’ve got another question. I made neutralisation and after night I get product with pH 8. But my sample delaminate…On the top my pH is 8, and on the bottom pH is 12. Should I change the quantity of NaOH…?

@Belassi ok:-) perhaps @Chemist77 could help:-)

Thank you @Belassi and @Chemist77, I will dilute NaOH to be more precisely.
@Belassi I am using electronical pH meter with electrode.
Could you tell me what pH do You obtain? And what temperature are you geting through whole process?

Hello I am new here and I would like to ask you about neutralising ABS Acid with NaOH. I’ve hot 30% ABS Acid which is yelowish, and I add drop by drop 30% NaOH. My problem is to get pH approximatelly 8. I’ve got at the begining pH 2 and after adding NaOH it is changing to 12 and IT is difficult to me to get pH 8. Do you know what I am doing wrong?
