1-(2-Pyridylazo)-2-naphthol Usage And Synthesis
Chemical Propertiesorange crystals
Agricultural UsesPan, also called hardpan or sole, is a hard stratum of strongly compacted soil caused by continual plowing to the same depth of hardened soil which has high clay content. The precipitated iron and silicates cement the soil particles and form pans. Pans often impede drainage and root growth. Pans can be broken up using a subsoiler .
Purification MethodsPurify PAN by repeated crystallisation from EtOH or MeOH. It can also be purified by sublimation under vacuum. Purity can be checked by TLC using a mixed solvent (pet ether/Et2O/EtOH; 10:10:1) on a silica gel plate. It has pK1 1.9 and pK2 12.2 in 20% aqueous ethoxyethanol. It chelates with copper [Pease & Williams Anal Chem 31 1046 1959]. [Beilstein 22 I 694, 22 III/IV 7073, 22/4 V 618.]
