| titleOfInvention | Composition for prevention of asphalt-resinous-paraffin deposits |
| abstract | FIELD: organic chemistry. n SUBSTANCE: invention relates to compositions used for prevention of precipitating asphalt-resinous-paraffin deposits from petroleum on oil field equipment, in critical zone of oil holes and in oil pipelines. Invention describes a composition used for prevention of asphalt-resinous-paraffin deposits that comprises oxyalklylated product of successive adding ethylene oxide and propylene oxide to alkyl phenol, modifying additive and organic solvent. As a modifying additive method involves using N-[alkylphenoxypoly(ethyleneoxy)-carbonylmethyl]ammonium chlorides or N,N'-bis-{[alkylphenoxypoly(ethyleneoxy)carbonylmethyl]ammonium}-propane dichlorides, or N-[alkylphenoxypoly(ethyleneoxy)carbonylmethyl]morpholinium chlorides in the following ratio of components, wt.-%: oxyalkylated product of successive adding ethylene oxide and propylene oxide to alkyl phenol, 20.0-25.0; modifying additive, 0.5-2.5, and organic solvent, the balance. Invention provides the effective prevention of precipitation of asphalt-resinous-paraffin deposits from petroleum. n EFFECT: improved and valuable properties of composition. n 2 cl, 13 ex |
