Zusammenfassung:The invention relates to a process for obtaining an odorant for fuel gases. According to the invention, the process consists in sulphurizing the ethanol and the t-butyl alcohol with sulphuretted hydrogen, at a temperature ranging from 300 ... 500 C preferably 415 C, the molar ratio between the alcohols being of 100: 5 ... 100:60, preferably 100: 200, in the presence of a catalyst mixture, there resulting an odorant mixture depending on the dosing ratio of hydrocarbons. Invenţia se referă la un procedeu de obţinere a unui odorizant pentru gaze combustibile. Procedeul conform invenţiei constă în aceea că se efectuează sulfurarea etanolului şi t-butil-alcoolului, cu hidrogen sulfurat, la o temperatură de 300...500°C, de preferinţă 415°C, raportul molar între alcooli fiind de 100:5...100:60, de preferinţă, 100:200, în prezenţa unui amestec de catalizatori, rezultând un amestec odorizant funcţie de raportul de dozare a hidrocarburilor. ŕ
