Abstract
Inventia se refera la un inhibitor de coroziune peliculogen pentru otel si cupru la instalatiile de distilare atmosferica si în vid a titeiurilor si la un procedeu de preparare a sa. Inhibitorul de coroziune, conform inventiei este un sapun al acizilor grasi sintetici cu o 2-limidazolina-1, 2-disubstituita în amestec adecvat de solventi si conditionat cu benztriazol. La concentratia de 5-20 ppm în distilat inhibitorul de coroziune conform inventiei, asigura o protectie anticorosiva de minimum 60% la atacul agresiv al acidului clorhidric, acizilor naftenici, oxigenului si hidrogenului sulfurat la prelucrarea titeiului prin distilare atmosferica ti în vid.
