Lubricant oil additive., Dodecane is a component of gasoline and is used as solvent, in organic synthesis, in jet fuel research, as a distillation chaser, and in the rubber and paper processing industries., We have recommended surrogate blends for Fischer-Tropsch (F-T) blends that consist of mixtures of n-dodecane, n-decane, and iso-octane. In addition, we have described a systematic approach to generating a specific blend to match a specific fuel. Compositions for specific surrogates of two different F-T fuels have been proposed that provide a best match to cetane number, H, C ratio, lower heating value, T50 boiling point, and chemical-analysis data. Tests of these blends against experimental data for flame-propagation and flame-extinction strain rate show good agreement., For more Uses (Complete) data for n-Dodecane (11 total), please visit the HSDB record page., Use Classification: Fragrance Ingredients, Fragrance Ingredients, Cosmetics -> Solvent, Emollient, Industry Uses: Fuel, Processing aids not otherwise specified, Lubricating agent, Other, Intermediate, Heat stabilizer, Not Known or Reasonably Ascertainable, Cleaning agent, Consumer Uses: Heat stabilizer, Fuel, Household Products: Information on 1 consumer products that contain Hydrocarbons, C4, 1, 3-butadiene-free, polymd., triisobutylene fraction, hydrogenated in the following categories is provided:, • Personal Care, Methods of Manufacturing: 1-Hexene is hydroborated with sodium borohydride and boron trifluoride in diglyme.
