| 应用领域 | Uses: Organic synthesis、They are used mainly in applications for which isoalkanes are not acceptable for biological reasons、e.g.、the production of detergents or proteins.、Higher n-Alkanes、Solid n-alkanes (paraffin waxes) are used in a variety of applications、... oxidation、and chlorination reactions.、Use Classification: Fragrance Ingredients、Methods of Manufacturing: The liquefaction of coal provides the greatest variety of saturated hydrocarbons. The Fischer-Tropsch synthesis produces alkanes from syngas (CO + H2) in the range C1 to C30 or higher depending on the process variant: depending on the catalyst employed、the synthesis yields predominantly liquid hydrocarbons in the gasoline range、along with gases from C1 to C4 when iron-based catalysts are used、while cobalt-based catalysts produce longer chain hydrocarbons in the diesel and wax range that often undergo、depending of the desired product slate、further processing、especially for gasoline generation. While iron-based Fischer-Tropsch catalysts generate complex mixtures that also include branched and olefinic hydrocarbons、cobalt-based catalysts produce streams that are rich in n-alkanes and are therefore suitable raw materials for detergents and for wax products.、Saturated Hydrocarbons、Suitable sources for n-alkanes with more than six carbon atoms are the appropriate petroleum distillate fractions、from which the n-paraffins can be isolated in high isomeric purity (= 95% linearity) by selective separation techniques、especially fractional distillation.、Formulations、Preparations: Grade: Technical.、General Manufacturing Information: Tricosane: ACTIVE、Gas-phase dehydrogenation of n-alkanes over noble-metal catalysts yield the corresponding n-alkenes at low conversion rates (ca. 10%) with predominantly internal double bonds. The corresponding alkenes can be isolated in high purity by selective molecular-sieve processes. |
