چکیده
|
The production of high grade phosphate fertilizers requires a good quality phosphoric acid since it is an important raw material for these industries. the present report describes an efficient and economical route for manufacturing phosphoric acid by treating rock phosphate with commercial hydrochloric acid followed by its separation from the crude mixture by solvent extraction using amyl alcohol as solvent. the acid,obtained by this method,is of high quality and could be upgraded up to density of 1.5 g/ml at 25 °c.
