Summary

The purpose of this study was to prepare some basic experimental data for mechanism study of Marangoni effect and to look for some effective additives to substitute 2-ethyl-1-hexanol or 1-octanol which are widely used in lithium bromide absorption refrigeration systems. In this study, absorption of water vapour into the 62 wt% lithium bromide solution with several six-carbon and seven-carbon alcohol additives such as 4-methyl-2-pentanol, 2-ethyl-1-butanol, 1-hexanol, 2,4-dimethyl-3-pentanol, 4-heptanol, 2-heptanol, and 1-heptanol were investigated by using a simple stagnant pool absorber. The results show that the effects of 1-hexanol and 1-heptanol on absorption of water vapour into aqueous lithium bromide solution are better than those of 2-ethyl-1-hexanol.
