1. Thermometers are filled with pentane or alcohol.

2. By SCFE unit using pentane as solvent, the Saudi Arabian vacuum residue was separated into 16 narrow fractions. The properties and composition of the narrow fractions and the VR were analyzed.

3. Benzene, cyclohexane and normal pentane etc. are frequently used as entrainers in industrial production of anhydrous alcohol through constant boiling and fine distillation.

4. A method for storing natural gas with pentane from natural gas condensate as solvent was proposed in this papaer.

5. Pentane combines advantageous physical and technical properties with good environmental data. As a blowing agent for polyurethane rigid foams, it is suitable for China market.

6. The aromatic structure of pentane asphaltenes is mainly peri condensed, while for resins the proportion of cata condensed and peri condensed aromatic structures is comparable.

6. Wish you will love sentencedict.com and make progress everyday!

7. The adsorption equilibria of normal paraffine in single and double solute n—pentane solution was studied dynamically on a 5A molecular sieve.

8. An asphalteneresin mixture obtained from Daqing crude oil is separated into pentane asphaltene (A) and resin (R).

9. This paper reviewed the methods of preparing the calibration gases of pentane and isopentane and discussed the GC analysis methods.

10. If someone is certifiably nuts, their breath may have notes of ether and pentane, according to one study.

11. A method of GC FID is established for the determination of reaction products in synthesizing TAME with methanol and isopentene as raw materials and pentane as solvent.

12. Cata condensed, peri condensed and biphenyl type aromatic unit structures coexist in resins subfractions and pentane asphaltenes, while the proportion of biphenyl type structure is relatively small.

13. Identification of retention time can be accurately obtained using a pentane peak as a standard.
