determine small amount methanol in solutions

Sep 2013
i like homebrewing but i don't know how to realize my homemade alcohol is safe even existing small volume of methanol has high risk to make someone blind i have tested my alcohol with red litmus paper but methanol and ethanol bout of them make it blue so this not good method. i added dicromate potasium to methanol but i didn't smell acrid from that sample so i found out it was not good method.pleasetell me a confident method to determine methanol in my homemade alcohol or any other sample.i want to drink that.

Testing for methanol

We can disitinguish between methanol and ethanol using the iodoform test which is easy to do without special equipment:
Detecting traces of methanol in a mixture would require more sophisticated methods such as IR spectroscopy. A somewhat simpler method involves reaction between the alcohol and HI: detection_methanol_presence_ethyl_alcohol.pdf?sequence=1

thank you,you gave two method to distinguish between methanol and ethanol my solution is a homemade alcohol a copmlex of water and ethanol ormaybe METHANOL so thefirst method is confident to recognize amall volume of methanol in my alcohol or it is ok for large volume of methanol i mean first method using idodine and NAOH.

Hi melika 444.
There is no danger that you will produce methanol but acetic acid or ethyl acetate are possibillities
