Well helllo all and simply stated help I am atempting to be left with a phosphonic acid and yes HI is the projected destination here is the snag the first ingridient is hydroxyethylidene -1,the 1-diphosphonic acid what little I've found says that water and the addition of hydrogen peroxide will activate the acid to it's peroxy state I guess ive done this however I'm still left with the#1 hydroxy bull honkey which sits at the front of this mess temperature variations seem to work in these typesof jams anyone know in what solvent the hydroxy is soluble in and not diphosphonic and at what temps?
