DeGeiso and Stalzer (1969) discuss the electrolytic moistureanalyzer, which is suitable for high-purity refrigerants. Other electronic hygrometers are available that sense moisture by the adsorption of water on an anodized aluminum strip with a gold foil overlay(Dunne and Clancy 1984).[r]
dard N-protecting groups are not affected by the reaction conditions. Similar success is achieved witha poly-TPP and iodine reaction mixture.16 Fmoc, Cbz, and Boc groups were utilized as N-protectinggroups, and methyl, allyl, benzyl, and t-butyl esters were employed. Hindered amino acids[r]
