Does diesel have a CAS number?
Fuels, diesel, no. 2 (CAS 68476-34-6) Can be absorbed through the skin.
How is cetane number defined?
Definition of cetane number : a measure of the ignition value of a diesel fuel that represents the percentage by volume of cetane in a mixture of liquid methylnaphthalene that gives the same ignition lag as the oil being tested. — called also cetane rating. — compare octane number.
How do I find my cetane number?
The cetane number of a PRF blend was defined as: CN = % by volume n-hexadecane + % by volume α-methylnaphthalene The structure of n-hexadecane (cetane) is shown in Figure 3.
What is the cetane number of diesel?
Modern highway diesel engines tend to require fuel with a cetane number ranging from 45 to 55. Typically, regular no. 2 diesel has a cetane number of 40 to 42, while Cenex® Premium Diesel has a cetane number of 47 to 52.
What is the CAS number for gasoline?
8006-61-9
Gasoline, also known as petrol, is a mixture of volatile hydrocarbons having 4 to 12 carbon atoms per molecule. It has an octane number of at least 60. It is used as fuel for internal combustion engines and as a solvent….gasoline.

What classification is diesel fuel?
Class II liquids
Class II liquids are combustible liquids that have a flash point at or above 100 °F (37.8 °C) and below 140 °F (60 °C). Typical Class II liquids include liquids such as camphor oil, diesel fuel, pine tar, and Stoddard solvent.
What is high cetane number?
Higher cetane numbers mean shorter ignition delay and at the same time a better performance of the diesel engine: The injected fuel burns more evenly and completely, which usually results in higher-quality exhaust air, especially with regard to soot, particulate matter and unburned hydrocarbons.
What does cetane number mean in diesel?
Cetane number. Cetane rating, also known as cetane number is a measurement of the quality or performance of diesel fuel. The higher the number, the better the fuel burns within the engine of a vehicle. The cetane number is similar to the octane rating in that it is a rating assigned to a fuel to rate the quality of its combustion.
What is the difference between Isocetane and cetane?
The cetane number (or CN) of a fuel is defined by finding a blend of cetane and heptamethylnonane with the same ignition delay. Cetane has a cetane number defined to be 100, while isocetane’s measured cetane number is 15, replacing the former reference fuel alpha-methylnaphthalene, which was assigned a cetane number of 0.
What is the cetane number of Alpha methylnaphthalene?
Alpha-methylnaphthalene, which has a long delay period, was assigned a cetane number of 0, but has been replaced as a reference fuel by 2,3,4,5,6,7,8-heptamethylnonane, whose cetane number is 15. All other hydrocarbons in diesel fuel are indexed to cetane as to how quickly they ignite under compression, i.e., diesel engine conditions.
What is the difference between cetane and heptamethylnonane?
Cetane has a cetane number defined to be 100, while heptamethylnonane ‘s measured cetane number is 15, replacing the former reference fuel alpha-methylnaphthalene, which was assigned a cetane number of 0.
