Lead (II) acetate, propanoate, and butanoate present only a melting transition at T = (452.6, 398.2, and 346.5) K, with DfH = (16.0, 13.1, and 15.6) kJ Æ mol1, and DfS = (35.3, 32.8, and 45.1) J Æ mol1 Æ K1, respectively. These temperature data correct to a great extent the historical values reported in the literature. These three members readily quench into a glass state. Their corresponding Tg values are (314.4, 289.0, and 274.9) K, respectively, measured by d.s.c. at a heating rate of 5 K Æ min-1.engjournal articlehttp://www.elsevier.com/wps/find/journaldescription.cws_home/622860/description#descriptionopen access548.73543.427/.428Lead (II) short alkanoatesGlassIonic liquidD.s.c.FTIRXRDCristalografía (Geología)
