preparation of 10% Methanolic HCl solution

It is a very economical method to make methanolic HCl. Here we form in situ HCl by mixing methanol with acetyl chloride.

For this, take 4036 micro litre methanol and cool it to 0 degree celcious using ice bath. then add 964 microlitre Acetyl chloride dropwise to it.

Mix it properly. It makes 10% solution of HCl in methanol.
