Coconut and coconut water contains no acetic acid, so you cannot extract it.....


Coconut water does not contain any acetic acid, so it is not possible to "extract" acetic acid from coconut water. Coconut water is 95% water, and around 2.5% of naturally occurring sugars. It can, however, be fermented to ultimately form "coconut vinegar", the total time required is about 6 weeks or so.

There is a number of websites in the public domain giving the procedure for doing this fermentation.

Please note that there is a very large difference between "acetic acid" and "vinegar". Vinegar is mainly water, and only contains around 4 - 5% of acetic acid.
