The invention relates to petrochemistry, more specifically to the use of additives to fuels and other combustible liquids.

The purpose of the invention is to increase the effectiveness of the additive in reducing the loss of hydrocarbon fuels and solvents from evaporation during storage.

This goal is achieved by the fact that in an additive containing a surfactant, aliphatic alcohol, oligodimethylsiloxane, a polyester based on ethylene oxide and propylene oxide, instead of oligodimethylsiloxane with a kinematic viscosity of 100 mm2 / s, an oligoester based on alkylene oxides (ethylene oxide and oxide ) with terminal epoxy groups with a mol.m. 703 conventional (technical

name Laproxide-703) and ethylene glycol in the following ratio of components, wt.%:

Fluorine-containing Quaternary ammonium salt 4.0-5.0 Polyester based on ethylene oxide and propylene oxide with a mol.m. 10003 srvc (laprol-10003) 9.0-10.0 Oligoester based on alkylene oxides with terminal epoxy groups with a mol.m 703 conventional

, (laproxide-703) 19.0-21.0 Ethylene glycol 4.0-5.0 Butanol-1 Up to 100 Ethylene glycol serves as a solvent for the surfactant. Laprol-10003 and Laproxide-703 are dissolved in ali00

Aliphatic alcohol-butanol-1 is a colorless, transparent, mobile liquid with a specific odor. It is produced by industry according to GOST 6006-78.

The proposed additive is added to hydrocarbon fuels and solvents in an amount of 0.2 May. %

The effectiveness of the additives was estimated by the average evaporation rate of hydrocarbon fuel and solvent when stored under static conditions for one month relative to fuel and solvent without an additive and fuel and a solvent with a prototype additive. Additive test results are presented in Table 1.

Evaporation rate tests were carried out under static conditions in glass beakers with an evaporation area of 32.1 cm2 at an air temperature of 17-20 ° C and an air humidity of 75-90%. The error in determining the evaporation rate is 0.05 g / day. Examples 1, 2, 3 in Table 1 differ in the percentage of components in the proposed additive (see Table 2).

In addition, tests were carried out on the effectiveness of the proposed additive to reduce the evaporation rate of aviation fuels (see table H). The test conditions and examples 1, 2 and 3 of the composition of the proposed additive are identical to those described above.

When adding the proposed additive to hydrocarbon fuels and solvent in an amount of 0.2 wt.%, The tested quality indicators of fuels and solvent vary within deviations of permissible GOST for test methods,

The data in Tables 1 and 3 indicate a more effective action of the proposed additive to reduce evaporation losses during storage of hydrocarbon fuels and solvents.
