Sulfur and sulfur compounds determined by potentiometric titration with the Ag Titrode

Sulfur and sulfur compounds determined by potentiometric titration with the Ag Titrode   Sulfur compounds contained in petroleum products not only have an unpleasant odor, they are also environmentally damaging and promote corrosion. Application details for hydrogen sulfide and mercaptans For determining hydrogen sulfide and mercaptans in liquid hydrocarbons (gasoline, kerosene, naphtha and similar distillates), [...]

Bromine Number（溴值） and Bromine Index（溴指数）

Bromine Number and Nromine Index The bromine number (BN) and the bromine index (BI) indicate the proportion of unsaturated compounds (usually C-C double bonds) in petroleum products. The method is used for the following products: Distillates with a boiling point below 327 °C (620 °F)  and a volume percentage of at least 90% of compounds  [...]

Initial Boiling Point（初馏点）

initial boiling point (IBP) According to American Society for Testing and Materials petroleum-analysis distillation procedures, the recorded temperature when the first drop of distilled vapor is liquefied and falls from the end of the condenser. Reference: Answers.com

Doctor Test（含硫测试）

Doctor Test A procedure using doctor solution/脱硫液 (sodium plumbite/亚铅酸钠) to detect sulfur compounds in light petroleum distillates which react with the sodium plumbite. This is a qualitative test for the presence of hydrogen sulfide, or mercaptans/硫醇 in the absence of hydrogen sulfide, in gasoline, jet fuel/航空煤油, kerosine/煤油 and similar petroleum products. Reference: Answers.Com ASTM UOP41 [...]
