naphtha
In addition, the intensities of the NMR signals of some naphtha oils, immersion oil and some polymer oils were measured.
      
Spectrophotometric determination of iron after separation of its 9,10-phenanthrenequinone monoximate on microcrystalline naphtha
      
Application of multivariate techniques for optimization of direct method for determination of lead in naphtha and petroleum cond
      
A direct method is proposed for the determination of lead in naphtha and petroleum condensate by electrothermal atomic absorption spectrometry (ET AAS) using palladium as a permanent modifier.
      
The procedure includes the dilution of 3?mL of sample (naphtha or petroleum condensate) to a final volume of 10?mL with xylene, and direct injection of 30?μL of this solution into the graphite furnace.
      
Recovery studies demonstrate that lead can be determined in naphtha and petroleum condensate using calibration with organic standard solutions.
      
This method was applied for the determination of lead in three petroleum condensate and two naphtha samples.
      
The concentrations found for the petroleum condensate was between 2.7 and 5.7?μg?L-1, while the naphtha samples did not contain any detectable lead.
      
The mutagenic potential of high flash aromatic naphtha
      
One such application is a mixture of predominantly 9-carbon aromatic molecules (C9 aromatics, primarily isomers of ethyltoluene and trimethylbenzene), which is removed and used as a solvent - high-flash aromatic naphtha.
      
A program was initiated to assess the toxicological properties of high-flash aromatic naphtha since there may be human exposure through inhalation or external body contact.
      
Pt-Re/Al2O3 prepared under different impregnating conditions were characterized by TPR and tested in naphtha and n-heptane reforming.
      
Coke deposition on naphtha reforming catalysts: I.
      
Coke deposition on naphtha reforming catalysts: II.
      
Fresh and coked catalysts were tested in two ranges of reaction conditions: model conditions (T=280-340°C, P=1 atm) and the conditions used in the naphtha reforming process (T=420-460°C, P=15 atm).
      
Evaluation of naphtha reforming catalysts by accelerated deactivation tests
      
Adventitious rooting occurred after subculturing excised shoots on a medium containing 1/2 strength MS salts, 1.5% sucrose, 1 μM each of IBA and α-naphtha-leneacetic acid (NAA), and 1 gl-1 activated charcoal.
      
The linear and branched oxygenated products obtained are equally useful in naphtha upgrading, as observed in the real El Palito naphtha tried.
      
Use of electrodeposition for refining Naphtha distillates obtained by catalytic cracking with trisodium phosphate
      
Surface-active products from oxidation of catalytic naphtha and subsequent sulfonation of the oxidation product
