Abstract

Przedmiotem zgłoszenia jest kompozycja dodatków przeciwutleniająco - stabilizujących do paliw silnikowych, zawierająca produkty acylowania polialkylenopoliamin bezwodnikiem alkenylobursztynowym i przeciwutleniacz wybrany z grupy obejmującej pochodną alkilofenolu i pochodną hydrochinonu, charakteryzująca się tym, że zawiera: od 92,0% (m/m) do 99,99% (m/m) alkenylobursztynoimido-amidów o kontrolowanej zawartości grup imidowych i amidowych, otrzymywanych sposobem obejmującym etap A i B oraz od 0,01% (m/m) do 8,0% (m/m) przeciwutleniacza w postaci tert-butyloalkilofenolu lub tertalkilo-hydrochinonu lub mieszaniny tert-butyloalkilofenolu i tertalkilo-hydrochinonu, w której stosunek masowy tert-butyloalkilofenolu do tert-alkilo-hydrochinonu zawarty jest w granicach od 4 : 1 do 1 : 4.The subject of the application is a composition of antioxidant and stabilizing additives for motor fuels, containing acylation products of polyalkylene polyamines with alkenyl succinic anhydride and an antioxidant selected from the group consisting of an alkylphenol derivative and a hydroquinone derivative, characterized in that it contains: from 92.0% (m / m) to 99, 99% (m / m) alkenyl succinimide-amides with a controlled content of imide and amide groups, obtained by the method including step A and B and from 0.01% (m / m) to 8.0% (m / m) of antioxidant in the form of tert -butylalkylphenol or tertalkylhydroquinone or a mixture of tert-butylalkylphenol and tertalkylhydroquinone, in which the mass ratio of tert-butylalkylphenol to tert-alkylhydroquinone is in the range from 4: 1 to 1: 4.
