Production of by-product potassium dihydrogen phosphate
Thread Content
Dear teachers, I have by-product potassium dihydrogen phosphate, and the current processing steps involve dissolution, filtration, purification, and recrystallization. The production result is either in the size of salt grains or in a paste-like form; what could be the problem? Please have the teachers analyze it

It seems I encountered this before; the acid contained aluminum or silicon crystals that gave it a paste-like consistency.
Later, no further in-depth research was conducted, and another phosphate was chosen instead. Besides, no one else will teach you this technique.
