| 发明名称 | Pentamethylheptane as a primary reference standard for cetane number | ||
| 摘要 | A composition useful as a Reference Standard for measurement of Cetane Number or for use as a standard for determining a Derived Cetane Number consists essentially of a blend of n-hexadecane and 2,2,4,6,6-pentamethylheptane. The disclosed Reference Standards can be used directly as substitutes for blends of n-hexadecane and 2,2,4,4,6,8,8-heptamethylnonane in ASTM D613-10a for determining Cetane Number, or in ASTM D6890, ASTM D7170 or ASTM D7668 to determine a Derived Cetane Number. | ||

| 主权项 | 1. A composition useful as a reference standard for measurement of a Cetane Number of a fuel, consisting of a blend of (1) n-hexadecane and (2) 2,2,4,6,6-pentamethylheptane, wherein the 2,2,4,6,6-pentamethylheptane has a minimum purity of at least 98% and the n-hexadecane has a minimum purity of at least 99%, such that the total amount of n-hexadecane and 2,2,4,6,6-pentamethylheptane in the blend is greater than 98%. | ||
