SOLUBILITY OF LITHIUM HYDROXIDE IN WATER AND VAPOR PRESSURE OF SOLUTIONS OF LITHIUM HYDROXIDE ABOVE 220 F
The solubility of lithium hydroxide in water was determined at 220 to 650 F. The literature furnished data for temperatures below 200 F. A maximum in the curve was found at about 240 and a minimum at 480 F. The variations in solubility, however, were relatlvely small. At 40, the solubility is 12.7 g LiOH per 100 g H/sub 2/O, while at 240, it is 17.7, and at 650 F, it is 16.5. The vapor pressures of 4.76 wt. % (2.09 molal), 8.59 wt.% (3.92 molal), and saturated (approximately 6.25 molal) lithium hydroxide solutions were measured as a function of temperature. At about 685 F, the more dilute solution showed a depression in vapor pressure of about 130 psi, the intermediate 154 psi, and the saturated 158 psi. The more dilute solution showed a greater deviation from Raoult's law than did the other two. Vapor-pressure data for sodium hydroxide solutions were compared with those for lithium hydroxide of similar concentration by weight and molality. (auth)
