Abstract : The heating of fuel samples (25 ml) was carried out in a thermostability testing device at temperatures from 100 to 200 C, with and without catalytically acting copper plate. The following inferences are drawn: (1) the sediment formation in heated T-1 fuel is inhibited by the addition of aliphatic primary amines, and this effect increases with the increase of the chain length of the organic radical, from C7-9 to C15; (2) the formation of oxidation products increases in the presence of the amines; a weak antioxidant effect is noted in the reverse order of amines as compared with the sediment formation; (3) the change in the amount and structure of the sediments and the size and the shape of the particles is caused by the antioxidant and by the dispersing properties of amines at certain temperatures, and possibly by the coagulating property at higher temperatures; (4) the mechanism of the dispersing effect is believed to consist in the absorption of the amines around the sediment particles in the form of envelopes which prevent coagulation; (5) the mechanism of coagulation possibly lies in the contact of the liquid part of the mixed (i.e., liquid + solid) phase of the sediment. The solid part is believed to soften and melt at elevated temperatures. (Author)
