Use of additives to improve the odor of hydrocarbon compositions and hydrocarbon compositions comprising such additives.

摘要

Hydrocarbon composition (A) comprising a major portion of at least a hydrocarbon liquid fraction (fuels or combustibles) comprises at least an additive (I) (1-2000 ppm mass). Hydrocarbon composition (A) comprising a major portion of at least a hydrocarbon liquid fraction (fuels or combustibles) comprises at least an additive (I) (1-2000 ppm mass) (bicyclic compound of formula (Ia)). R 1-R 3H, 1-10C hydrocarbon (optionally comprising one or more heteroatoms). Independent claims are also included for: (1) preparation of (A) having an improved odor; (2) additive composition for diesel oil/domestic fuel oil comprising (% mass): detergent additive (5-50), procetane additive (0-60), filterability additive (0-20), (I) (0.1-20) or perfumed composition (containing the additive); (3) additive composition for domestic fuel oil comprising (% mass): combustion promoter agent (5-60), additive antioxidant (1-20), flow point additive (5-20), (I) (0.1-20) or perfumed composition containing the additive; (4) method to improve the odor of (A) (gasoline fuel, diesel fuel oil or domestic fuel oil) comprising the addition of whole or part of hydrocarbons having (I) (alone or in mixture with other reodorants additives); and (5) method to eliminate bacteria and/or fungi from (A) or to warn their appearance in (A) comprising the addition of whole or part of hydrocarbons having (I).
