Determine coal tar components
Thread Content
Does anyone have information on the components of coal tar? I’m looking for detailed details – not information organized by fractions, but rather the specific names of chemical substances along with their concentrations. Thank you!
2. A brief description of the characteristics and conditions of this noun. At room temperature, coal tar is a black, viscous liquid; the high-temperature coal tar produced during coking has a higher density, ranging from 1.160 to 1.220 g/cm3. It is mainly composed of polycyclic aromatic compounds, with a low content of alkyl aromatics; it contains many high-boiling-point components and exhibits good thermal stability. Its components contain a high amount of naphthalene, while the amounts of the other components are relatively low; the main ones include 1-methylnaphthalene, 2-methylnaphthalene, acenaphthene, fluorene, oxofluorene, anthracene, phenanthrene, carbazole, cherenene, quinoline, pyrene, etc. 3. Processing technology of this product: The various components of tar have different properties, but there are many components with similar properties. It is necessary to first use distillation to separate out the various fractions, so that the individual components such as phenol, naphthalene, and anthracene can be concentrated in the corresponding fractions. Subsequently, physical and chemical methods are used for further separation. The fractions below 170°C are light oils; the fractions between 170°C and 210°C are mainly phenol oils ； The fraction at 210–230°C is mainly naphthalene oil ； The fraction at 230–300°C is mainly washing oil ； The fraction between 280–360°C is mainly anthracene oil ； The fraction with a temperature range of 280–360°C is anthracene oil ； The initial boiling point of the dianthracene oil fraction is 310°C, and it reaches 400°C at 50% distillation.
Thank you to the friend in floor 2, but I need the specific components and their contents in more detail, not just the fractions
Main components of tar: 1. Light oil fraction – 0.5%, 2. Phenol oil fraction – 1.2%, 3. Coarse powder – 1%, 4. Industrial naphthalene – 8-10%, 5. Washed oil – 5-7%, 6. Anthracene oil fraction – 24-26%, 7. Asphalt – 54-60%
Go to the resource section and look for a book titled \"Recycling and Processing of Chemical Products from Coking\"; it contains very detailed information
\"Coal Tar Chemical Engineering\" is explained very clearly
