I'm planning to start experimenting with composting glycerine, but I want to neutralise the KOH first. I've tried sulphuric acid, that made a gluggy mess, and also hydrochloric acid which was a little better. But I really want to try using Phosphoric acid as this will produce potassium phosphate which I understand to be a fertiliser.
Anybody know where I can buy industrial grade phosphoric acid in reasonable quantities (& price), maybe 5-20L? I know that Rust Converter contains phosphoric acid but this will be a very expensive way to buy it in such small amounts.
