The control of water evaporation was studied at Jodhpur (Rajasthan) on aluminium pans and specially built concrete tanks with n-alkoxy ethanol, CH/sub 3(CH/sub 2)16 CH/sub 2 O. CH/sub 2 CH/sub 2 OH. Effect of different solvents was studied. Hydrocarbon solvents gave the best performance. Alcoholic solutions gave poor results. It was found that n-alkoxy ethanol always gave higher reduction in evaporation than cetyl alcohol or stearyl alcohol or their admixture, singly or combined with n-alkoxy ethanol in different proportions. The material heated upto 110 degree Celsius was stable and did not show any loss in its efficiency and performance. 25-35 per cent conservation of water can be obtained during summer and 50-60 per cent during winter. For the other periods the saving lies between these limits.
