Method of recovering 4-methyl-2-pentanone used to extract molybdate disodium phosphate complex |
| abstract |
The invention relates to the field of pure preparationnlaboratory chemicals, speciallynpurification of 4-methyl-2-pentanone usednfor the extraction of molybdate disodium phosphatencomplex from the aqueous phase for photometricnphosphorus determination, washing off the usedn4-methyl-2-pentanone 3 with a small amountn5 to 10% sodium hydroxide solution ornpotassium, then neutral to waternreaction and finally rectification. |
