main use a tetra-cyclic aromatic hydrocarbon. Fluoranthene is one of the products of coal tar processing. The content of fluoranthene in high temperature coal tar is about 2.5%, which is mainly concentrated in anthracene oil fraction. Fluoranthene can be used as a raw material for dyes and medicines. Such as purple vat dye 3-amino -8, 9-phthaloyl fluoranthene, yellow dye 11, 12-phthaloyl fluoranthene, cholera drug 10b propionate -1,2, 3-trihydrofluoranthene and spasmodic drug 10b aminoalkyl -1,2, 3-trihydrofluoranthene. Fluoranthene can also be used as a non-magnetic metal surface flaw detector.
application fluoranthene can be used as a non-magnetic metal surface flaw detection fluorescent agent, dye intermediate, and pharmaceutical intermediate.
method for extracting fluoranthene using anthracene oil fraction or asphalt distilled oil as raw material, vacuum distillation is carried out with batch distillation tower, and fluoranthene fraction at 375~385 ℃ is cut, which contains about 50% fluoranthene. In order to obtain products with high fluoranthene content, fluoranthene fractions must be recrystallized many times. The mixture of 30% solvent oil and 70% ethanol was used as solvent, and the ratio of fluoranthene fraction to solvent was 1: 1. The fluoranthene fraction and the prepared mixed solvent are loaded into the crystallizer, heated while stirring until it is completely dissolved, then cooled, crystallized, and then centrifuged, so as to repeat several times until qualified fluoranthene is obtained.
Toxicity and carcinogens Fluoranthene is classified as a potential carcinogen compound (polycyclic aromatic hydrocarbon). Fluoranthene does not exhibit mutagenic or primary carcinogen properties, but it is a co-carcinogen. It has been confirmed that fluoranthene is toxic to various freshwater organisms and seawater organisms.
exposure opportunities and health hazards processing coal, petroleum and other organic raw materials at high temperature can produce fluoranthene, which is also known to be the product of plant biosynthesis in nature. It is ubiquitous in various environments, such as drinking water, food ingredients, and cigarettes. Workers in certain occupations such as coking and steelmaking may be exposed to fluoranthene, especially smokers are exposed to high concentrations of fluoranthene.
use can be used as magnetic metal surface flaw detection fluorescent agent and used to make synthetic dyes, drugs, etc.
used as non-magnetic metal surface flaw detection fluorescent agent to synthesize yellow, Blue vat dyes, manufacturing medicine, etc.
It can be used as a fluorescent agent for surface flaw detection of 100 magnetic metals and for the preparation of synthetic dyes, drugs, etc.
It can be used as a fluorescent agent for surface abrasion of non-magnetic metals; dye intermediates; pharmaceutical intermediates
production method recovery from coal tar. The best raw materials for extracting fluoranthene are distillates (oils) in the oxidation process of Ⅱ anthracene oil and asphalt. These raw materials are put into intermittent direct fire heating distillation, and a small amount of superheated distillation is introduced into the pot. Distillation is carried out at a vacuum of 0.09MPa, and a small amount of superheated steam is introduced into the pot at the same time. The distilled vapor is cooled to a temperature higher than the melting point through a rectification tower, a condenser and a cooler, flows into the bad, crystallizes the distillate at 375-358°C, and centrifuges to deoil to obtain crude fluoranthene. Crude fluoranthene is recrystallized with mixed solvents (30% light solvent oil and 70% ethanol) to obtain the finished product. The yield of narrow fraction at 375-385 ℃ is 40%, and the purity of fluoranthene can reach 99%.
