The importance and role of isooctyl nitrate in the chemical industry
Isooctyl nitrate plays an important role in the chemical industry:
As a diesel additive, it increases the cetane number of diesel and improves combustion performance.
Isooctyl nitrate can increase the cetane number of diesel fuel, thereby improving its combustion performance. The cetane number is an important indicator of diesel fuel. It indicates the ability of diesel fuel to self-ignite in compression ignition engines. Isooctyl nitrate can increase the cetane number of diesel fuel, making it more likely to self-ignite, thereby improving engine efficiency and performance.
Used as a fuel additive to reduce emissions and reduce environmental pollution
Isooctyl nitrate can reduce diesel engine emissions and reduce environmental pollution. Diesel engines will produce some harmful substances during the combustion process, such as nitrogen oxides, particulate matter, etc. Isooctyl nitrate can improve the combustion performance of diesel and reduce the production of these harmful substances, thereby reducing the impact on the environment.
