  LABSA neutralisation using Alkali.

  Posted by HussainAli on December 5, 2020 at 7:46 am

  I am using LABSA 96% to make dishwashing liquid. I wanted to ask that how can I calculate the exact mass of alkali i.e NaOH required to neutralise my LABSA.

  Hello

  In my experience, it needs 10 kilo LABSA against almost 1 kilo NaOH, THEN adjust PH with TEA.

  Hi there. 

  Is there any exact quantity of NaOH used to just neutralise it so that I don’t have to re adjust the pH later by adding acid?
