| titleOfInvention | Perfluoroalkyl sulfonyloxy benzyl heterocyclic corrosion inhibitor as well as preparation method |
| abstract | The invention discloses a perfluoroalkyl sulfonyloxy benzyl heterocyclic corrosion inhibitor as well as a preparation method and application thereof. A structural general formula of the fluorine-containing corrosion inhibitor is as shown in formula I, wherein Rf is either perfluoro butyl or perfluoro hexyl, and R is a heterocyclic group, including triazole, benzotriazole, benzothiazolethiol, benzimidazole, mercapto benzimidazole, imidazole, 2-methylimidazole, 1,4-dimethylimidazole, etc. The perfluoroalkyl sulfonyloxy benzyl heterocyclic corrosion inhibitor is prepared by the following steps: conducing sulfonic acid esterification on fluorine-containing precursor materials (perfluoro butyl sulfuryl fluoride and perfluoro hexyl sulfuryl fluoride) and para hydroxybenzene methanol, implementing chlorination with a halogenating reagent, and reacting with a heterocyclic compound. By introducing the fluorine-containing group to corrosion inhibitor molecules, the designed and synthesized fluorine-containing corrosion inhibitor disclosed by the invention is free of phosphor element harmful to the environment, and has excellent corrosion inhibiting effect at low concentration; and the partial fluorine-containing corrosion inhibitor disclosed by the invention can achieve a controlled-release effect more than 95% at concentration of 5*10＜-4＞M (as shown in specification). |
