Description
technical field [0001] The invention belongs to the field of instrument analysis, in particular to a quinoline insoluble measuring device. Background technique [0002] Coal tar is a mixture of many compounds, its main components are completely suitable for the production of needle coke, but it contains more quinoline insoluble matter, so the pitch obtained from coal tar processing cannot be used directly to produce needle coke. Quinoline insolubles are referred to as QI for short, and their average relative molecular mass is 1800-2600, and the C / H atomic ratio is greater than 1.67. According to the formation of QI, it can be divided into primary QI (primary QI) and secondary QI (secondary QI). Primary QI It is present in coal tar, which is transferred to bitumen when the coal tar is distilled. The secondary QI is an aromatic hydrocarbon polymer with a larger molecular weight formed during the heating of the asphalt, which exists in the asphalt in the form of solid particle...
