Сetane improver additive 2 – ethylhexyl nitrate

For what сetane improver additives are necessary?

Сetane improver additives managed to get so wide distribution due to properties which arise at their addition to fuel. Increase of cetane number causes some favorable properties of fuel: successful start of the engine in the conditions of low temperatures, big environmental friendliness (emission of harmful substances in the atmosphere considerably decreases) and silence of work in comparison with work on fuel with a smaller cetane-indicator.

Structure

High-pure 2- ethylhexyl nitrate.

Features which should be known:

Popularity of сetane improver additive 2- ethylhexyl nitrate is explained by a number of advantages:

• Interchangeable with additives of foreign production;
• Applied in a package with antiwear and the dispersant and depressor additives with full saving of characteristics of diesel fuel, including long storage;
• Tests of diesel fuels with the Additive showed that domestic additive doesn't concede on quality to foreign analogs;
• It is registered according to requirements of Regulations of REACH.

Where to use?

It is possible to distinguish three main directions of use of additive 2- ethylhexyl nitrate:

• Average distillates with narrow fractional structure and temperature distillation indicators: DT (90-20%) from 70 to 100°С; DТ (final boiling point - 90%) from 17 to 25°С;
• Wide fractions of distillates with DT value (90-20%) from 100 to 120°С final boiling point below 380 °C (distillation by ASTM D 86 method);
• High-boiling distillates with final boiling point above 380 °C.

It is recommended to use cetane improver additives with dispersant and depressor and antiwear ones. Their combined use allows to achieve increase in profit of oil refinery. It occurs at the expense of the high selling cost of diesel fuel which comes true the increased quality of ignition, low noise of the engine, the reduced issue and easy start in cold.

Action of 2- ethylhexyl nitrate in figures:

After addition of 0,6% of the additive to diesel fuel the cetane number from 48 units raises to 57,8. Diesel Fuel EURO in accordance with GOST P 52368-2005 as a result of working tests of cetane improver additives showed itself from the best side. It is confirmed by the following test reports:
