STUDYING SURFACEACTIVE PROPERTIES OF EMULSIFIERS RECEIVED FROM WASTE SUNFLOWER OIL
Studied surface-active properties of surfactant samples of different nature at the interface of the solution-air (surface activity, the thickness of the adsorbed layer, the magnitude of the molecular sites, the adsorption energy, the maximum adsorption). On the basis of the Langmuir isotherm for soapstock subjected to alkaline hydrolysis, was calculated the area occupied by one molecule of surfactant monolayer (Sm). Found the value of surface pressure , which are bound in the fi lm bilayer structure (state collapse), or moving from one phase state to another, and isothermal compression of the surface monolayer
