In my country, there is over-the-counter access to syrup containing approximately 2 grams of phenobarbital per 100 milliliters (valocordin/corvalol).How to extract phenobarbital from it in the safest way (preferably so that the apartment does not smell of them)...I found information on the freezing method on the Internet, they say: pour half a liter of water with 100 ml of syrup and freeze, alcohol and esters will remain at the top, and phenobarbital in ice, then you need to defrost the ice and collect the sediment.So, how reliable is this method, and how many percent of the substance will I lose? You can explain this method, or suggest another method...
