GSO ISO 5272:2017 工业用甲苯规格

This International Standard specifies requirements for two grades of toluene suitable for industrial purposes. Grade 1 (synthesis grade) is a high quality grade normally required for use only as a chemical feedstock. Grade 2 (ordinary grade) relates to commercially pure toluene and is suitable for most normal commercial uses. This International Standard is applicable to material which consists essentially of toluene (C6H5.CH3).

This International Standard specifies a method for the determination of the sulphur content of aromatic hydrocarbons boiling below 200 °C. The method is directly applicable to sulphur contents of 0,1 to 30 mg/kg; higher contents may be determined by suitable dilution of the sample. Alkylsulphones, arylsulphonic acids and arylsulphonates all give incomplete recovery of sulphur.

Standard Test Method for Analysis of Benzene by Gas Chromatography with External Calibration

ASTM D1555-16 工业芳香烃和环己烷的体积和重量计算的标准测试方法

1.1 This standard is for use in calculating the weight and volume of benzene, toluene, mixed xylenes, styrene, orthoxylene, meta-xylene, para-xylene, cumene, ethylbenzene, 300 to 350°F and 350 to 400°F aromatic hydrocarbons, and cyclohexane. A method is given for calculating the volume at 60°F from an observed volume at t°F. Table 1 lists the density in Vacuo at 60°F for chemicals used to develop the relationship. Densities (or weights) “in vacuo” represent the true density (or weight) if measured in a vacuum without the buoyancy effect of air acting on the liquid. It is representative of the actual amount of product present. Densities (or weights) “in air” represent what would actually be measured on a scale. The difference is on the order of 0.13 %. Modern densitometers measure density in vacuo and the ASTM recommends the use of in vacuo densities (or weights). 1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard. 1.2.1 A complete SI unit companion standard has been developed in Test Method D1555M. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
