Lithium bromide solutions

Environment Internal Untreated water at 42°F (6°C) External Lithium bromide solution at 40°F (4°C) and a partial pressure of 4 mm of mercury... 

Absorption-type refrigerators operating with strong lithium bromide solutions can also be inhibited by a number of chemicals. Thus, a mixture of lithium hydroxide -I- BTA -I- sodium molybdate has been reported . 

Information recently released (14) shows that the double effect air conditioning version of Rotex has achieved a coefficient of performance of 1.0 at a temperature lift of 35°C using lithium bromide solution. This unit is about to enter field trials. Its high performance is entirely due to the intensity of the heat and mass transfer environment generated on the liquid film flowing over the discs. 

Transfer the supernatant from step 2 by cannula to the copper(l) cyanide/ lithium bromide solution. Once the transfer is complete, add valeryl chloride (1.4 g, 11.6 mmol) and allow the reaction mixture to warm to room temperature as it stirs overnight. 

The most commonly used absorption-refrigeration system operates with water as the refrigerant and a lithium bromide solution as the absorbent. This system is obviously limited to refrigeration temperatures above the freezing point of water. It is treated in detail by Perry and Green.t For lower temperatures the usual system operates with ammonia as refrigerant and water as the solvent.

Presumably, the difference between the two groups of compounds is due to differences in the coordination of water and chloride to the U(III). The authors regard the red compound as containing a chlo-rouranate(III) anion. Analogous bromo compounds could not be obtained though a strong absorption at about 18,300 has been reported for in concentrated lithium bromide solution (35).
