Industrial waste of production of dioctyl phthalate in OAO Gazprom neftekhim Salavat» is the stillage bottoms of rectification 2-ethyl hexanol (KOREG), which is a mixture of 2-ethylhexanol and the heavy reaction products. It can be used as a commercial product without further processing, for example, as an additive to diesel fuel, solvent or as an alcohol component for the production of inexpensive plasticizers. In order to diversify the ways to using KOREG was conducted research its chemical composition and selected not the previously described 2,4-diethyl-1,3-oktandiol whose concentration in KOREG can reach 25%.
Key words: 2,4-diethyl-1; 3-oktandiol; identification of chemical composition; skilled utilization; stillage bottoms of rectification 2-ethyl hexanol.
