Product description
301. In the determination of adipic acid in the butadiene hydrocarboxylation product by paper chromatography, the spots obtained, developed with methyl red, were cut out. dried and weighed. For standard mixtures with different contents of adipic acid, the following data were obtained:
Weight of acid, mg 5 10 15 20
Mass of paper with a spot, mg 61 106 146 186
A portion of the analyzed sample m1 (mg) was dissolved in V (ml) of water, and 0.05 ml portions of the resulting solution were chromatographed. The mass of the obtained spots was m2 (mg). Determine the percentage of adipic acid in the analyzed product according to the following data:
task number 301
m 1, mg 100
V, ml 10
m2, mg 85
