일반 설명
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Heptane is an environmentally preferable solvent and greener alternative to hexane and thus has been enhanced for "Safer Solvents and Auxiliaries". Click here for more information.
The product is a mixture of heptane isomers with ≥25% n-heptane. The influence of the molecular structure of heptane isomers on the combustion rate was investigated. The thermodynamic changes on mixing heptane isomers with hexadecanes were reported. The performance of Pd/SAPO (palladium/silicoaluminophosphates)-5 and Pd/SAPO-11 molecular seives in the hydroconversion of heptane isomers was studied. Photolysis of heptane isomers by one-color 157nm ionization was analyzed using ion imaging and time-of-flight mass spectroscopy.
