• Crystal water and dissociation vapor pressure of the hydrates of alumino-p-aminosalicylic acid and calcium alumino-p-aminosalicylate were measured. Measurement of loss in weight showed that there are three moles of crystal water in Al-PAS and seven moles in Al-PAS-Ca. Thermobalance method showed that a pentahydrate of Al-PAS-Ca would be present besides the heptahydrate. Al-PAS is labile above 140°and undergoes decomposition but Al-PAS-Ca was found to be comparatively stable even at 180°. Dissociation vapor pressure of the heptahydrate of Al-PAS-Ca was measured and heat of dissociation at around room temperature was calculated. Stability of these complex compounds in the air was also examined.
