    Hydrolysis of coconut oil was carried out with alkali, and acid fraction was separated. The obtained acid fraction was propoxylated with propylene oxide at 1: 1, 1: 3, 1: 5, and 1: 7 molar ratios and 140 150 degrees C. Physico-chemical as well as surface activity parameters of these propoxylates have been determined. Petroleum-collecting and petroleum-dispersing properties of the propoxylates have been studied on thin oil slick on the surface of water with varying degrees of mineralization. The influence of various factors (petroleum layer thickness, the water salinity, and the nature of petroleum) on petroleum-collecting and petroleum-dispersing properties was studied. [GRAPHICS] .
