Where it is used

Documented applications: Uses: Used as a solvent (inks and degreasing) and in chemical research and production, Used in paper processing, [HSDB], Metal Degreasing [Category: Clean], Pulp and Paper Processing [Category: Industry], Textiles (Printing, Dyeing, or Finishing) [Category: Industry], Solvent, organic synthesis, distillation chaser, jet fuel research, Manufacturing paraffin products ... 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. Aqueous potassium hydroxide is then added followed by aqueous silver nitrate. The major product is n-dodecane (66%)., Dodecane is isolated from the kerosene and gas oil fractions of crude oil by selective adsorption and subsequent desorption to yield mixtures of paraffins that can be separated by fractional distillation., Impurities: The common impurities or contaminants, minor products, associated with the synthesis of n-dodecane are 5-methyl undecane (5%) and a mixture of 1-hexene and n-hexane., U.S. Production: 2023: 100, 000, 000 - <250, 000 lb, 2022: 50, 000 - <100, 2021: 50, 2020: 50, (1977) AT LEAST 2.27X10+10 G, (1982) PROBABLY GREATER THAN 6.81X10+6 G, Dodecane listed as a High Production Volume (HPV) chemical (65FR81686).
