The melting points of the compounds were determined on a Thoshniwal electric Melting point apparatus and the values were uncorrected. The purity of all the compounds was routinely checked by TLC on Silica gel-GF 254 (Merck) coated plates. Spotting was done by iodine in iodine chamber. The UV spectra of the compounds were The melting point ranges of all solids will be determined. You will also weigh each solid you obtain to determine the percent recovery of your procedure. Remember, though, that you only have two compounds in your unknown mixture so that you should not isolate solids from all of the extracts.
