Definitions
- the present invention relates to a new composition of multifunctional additives improving cold operability of middle distillates. She aims in particular the improvement of dispersing properties, anti-sedimentation and lowering point temperatures flow point and cloud point but also a improvement of the cetane of these distillates for a use as fuel for diesel engines and in fuels such as fuel oil for boilers.
- Cold operability corresponds to a temperature limit at which middle distillates can be used without clogging problem. She is intermediate between cloud point temperature (ASTM D 2500-98) characteristic of the onset of crystallization of paraffins in the distillate and the pour point of the latter (ASTM D 97-96a).
- paraffins are crystallized at bottom of the tank, they can be dragged starting in the fuel system and clogging in particular filters and prefilters placed upstream of the systems injection (pump and injectors). Likewise for storage domestic fuel oils, paraffins precipitate in the bottom tank and can be dragged and obstruct the pipes upstream of the pump and the supply system of the boiler (nozzle and filter). It is obvious that the presence of solids, such as paraffin crystals, prevents normal circulation of the middle distillate.
- TLF additives Temporal Limit of Filterability

- additive 1 consists of a copolymer comprising maleic anhydride units and octadecene units in a molar ratio 1/1, R 1 , R 2 , R ' 1 and R' 2 being identical and corresponding to dodecylamine radical.
- additive 2 consists of a copolymer comprising maleic anhydride units and octadecene units in a molar ratio 1/1, R 1 and R ′ 1 being a hydrogen atom, R 2 a butyl radical and R ′ 2 being a dodecyl radical.
