Study of the adsorption of n-heptane and 1-heptane by aerosil
(1985)
Adsorption isotherms of 1-heptene and n-heptane were determined at three near-ambient temperatures on a nonporous silica (Aerosil 200 They appear to lend support to the hypothesis that the double bond of the olefins ...
Structural features of silicas prepared in n-heptane/water/ethanol/sodium dodecylsulfate microemulsions
(Elsevier B.V., 2012-05-01)
Silica aerogels were prepared from hydrolysis of tetraethoxysilane (TEOS) in n-heptane/water/ethanol/ sodium dodecylsulfate (SDS) microemulsions and ambient pressure drying (APD). APD was carried out after silylation of ...

Dehydrocyclization of n-heptane over a PtBa/Kl catalyst: Reaction mechanism
(Elsevier Science, 2005-04)
The dehydrocyclization of n-heptane to toluene over a 1 wt.% PtBa/KL catalyst was studied in a fixed bed tubular reactor, at 723 K, 100 kPa and space-time in the range of 1.8-117.0 g h mol-1. The catalyst was prepared by ...
Effect of barium and lanthanum oxides on the properties of Pt/KL catalysts in the n-heptane dehydrocyclization
(Elsevier, 2000-07)
Six fractions of zeolite KL were impregned with 1, 3 and 5 wt% of Ba or La, respectively, with nitrate precursors aqueous solutions. After calcination at 873 K to form BaO or La2O3, 1 wt% of Pt was incorporated to the ...
Migration of Tinuvin P, a UV stabilizer, from PET bottles into fatty-food simulants
(1999-12-01)
Tinuvin P migration from Polyethyleneterephthalate (PET) bottles was investigated using several fatty-food simulants such as olive oil, soybean oil, n-heptane and iso-octane, at exposure conditions of 2-10 days at 40 °C ...
