FIELD: chemistry.SUBSTANCE: inhibitor of asphaltresinparaffin sediments, obtained with the application of an alkylacrylate copolymer and aromatic solvent, obtained by the interaction of the copolymer in toluene, which has the mol. weight 6000-8000, a mixture of alkylacrylates, which contain, wt %: alkylacrylate C- 65, alkylacrylate C- 25, alkylacrylate C- 10, with dodecylamine acrylate, and dodecylamine sulphate with heating with mixing to 80°C, introduction of a 8.8-16.6% solution of an azobisisobutyronitrile in toluene initiator, exposure for 5 hours at 90-100°C with the following component ratio, wt %: copolymer of the said mixture of alkylacrylates with dodecylamine acrylate 45-57, dodecylamine sulphate 2-3, toluene - the remaining part.EFFECT: increased efficiency of preventing the formation of asphaltresinparaffin sediments in paraffinic, highly-paraffinic oils and gas condensates.4 ex, 1 tbl |
