FIELD: analytical chemistry; water-sensitive pastes; determination of interface between petroleum products or oil and water in reservoirs, tanks, settling purification plants.
SUBSTANCE: proposed paste contains phenol phthalein, methyl red at ratio of (2-10):1, triethanoamine and chalk of fraction 100-200 mesh at the following relationship of components, mass-%: triethanoamine, 30-40;phenol phthalein, 1-4; methyl red, 0.3-1.0; chalk of fraction 100-200 mesh, up to 100.
EFFECT: enhanced stability of paste; facilitated procedure of analysis of water-to-heavy petroleum product interface.
