The Preparation of an Experimental Batch of the Additive DF-11 at the Polotsk Petroleum-Refining Plant (NPZ)

During the synthesis of the experimental batch of the additive under laboratory conditions, it was established that to achieve the required equivalent of alkaline hydrolysis for the prepared additive, it is sufficient to give 10 percent oil to the final dilution instead of 18.7 percent according to regulation. The data received makes it possible to draw the conclusion that the DF-11 additive can be prepared according to the regulation of the Institute of Chief of Chemical Service, Academy of Sciences, USSR under industrial conditions on the basis of equipment for producing the additive VNIINP-360 under the condition of developing the by-product node of the solvent.
