Abstract
New acid corrosion inhibitor OPC-2000 has been developed for a single stage process of isoprene synthesis. Gravimetric method has found high effectiveness of the inhibitor in conditions of dilute ortho-phosphoric and sulfuric acids towards alloys Incoloy 825 and 12X18H10T being applied within the range of 10-16 g/dm3. According to electrochemical investigation, OPC- 2000 is an anodic class inhibitor. It has high dispersing properties (no sediment formation in reactors), the fact being confirmed in the course of PJSC Nizhnekamsneftekhim’s industrial trials while a single stage of isoprene synthesis.
