Abstract

Inventia se refera la o compozitie biocida si la un procedeu pentru prepararea acesteia. Compozitia este constituita din 35...70% greutate 2-imidazolina-1,2-disubstituita avînd structura chimica data de formula: (vezi formula) în care R este radicalul naftenil provenind de la acizii naftenici din petrol, sau din motorina, sau din ulei, tehnici sau distilati, într-un amestec care mai contine 1...27% greutate petrol nesaponificabil, sau motorina nesaponificabila, sau ulei nesaponificabil, 17...35% greutate produse secundare constituite din amidoamine si amido-imidazoline si 15...30% greutate toluen sau oxilen sau amestec de xileni sau de xileni bruti si se caracterizeaza printr-un continut total de azot de 6...11% greutate si o cifra totala de bazicitate de 150...240 mg KOH/g. procedeul de preparare a compozitiei bioacide, conform inventiei, consta din condensarea termica a unor cantitati bine definite de dietilentriamina si acizi naftenici din petrol, sau din motorina, sau din ulei, tehnici sau distilati, continînd 55...99% greutate acizi naftenici, 1...45% greutate, nesaponificabile si indice de aciditate...The invention relates to a biocidal composition and to a process for its preparation. The composition consists of 35-70% by weight of 2-imidazoline-1,2-disubstituted having the chemical structure of the formula: wherein R is the naphthalenyl radical derived from petroleum naphthenic acids or from diesel oil, or from oil, techniques or distillates, in a mixture which further contains 1 ... 27% by weight of unsaponifiable oil, or unsaponifiable gas oil or unsaponifiable oil, 17 ... 35% by weight of by-products consisting of amidoamines and amidoimidazoline and 15 ... 30% by weight of toluene or oxylene or a mixture of xylenes or xylenes and characterized by a total nitrogen content of 6 ... 11% by weight and a total basicity of 150 ... 240 mg KOH / g. the process for preparing the bioacid composition according to the invention consists in the thermal condensation of well-defined amounts of diethylenetriamine and naphthenic acids from petroleum or diesel oil or from oil, techniques or distillates containing 55-99% by weight of naphthenic acids, 1 ... 45% weight, unsaponifiable and acidity index ...
