Versuchsvorschrift

In a preferred method, Oberley '010 reacts dicyandiamide with phosphoric acid for 35 to 45 minutes in water to form guanylurea phosphate (GUP), in a solution that contains 50-70 percent solids. The reaction is only allowed to proceed to about 80-95 percent completion, in order to prevent the formation of insoluble precipitates. Boric acid is then mixed with the GUP solution, and the mixture cooled to ambient temperature and diluted to from 3 to 18 percent solids.
