If you mean Caustic Soda that is the same thing as Lye.
They are both Sodium Hydroxide (NaOH)
If you are getting liquid caustic soda (a NaOH water solution) use it in the titration step.
You should be able to find the percentage of NaOH on the label somewhere then dilute it to .1%.
If there are other chemicals present in the solution I would not use your liquid caustic soda.

you can recover unreacted methanol from both the glycerin and BD products of the reaction. In fact it is recommended that you do so as it makes cleaning the BD easier and cheaper plus the methanol can be reused.
