Pyrene

   Also found in: Dictionary/thesaurus, Wikipedia 0.01 sec.
Pyrene 

an aromatic hydrocarbon; pale yellow crystals. Melting point 150°C; boiling point, 390°C. It is freely soluble in ether and benzene, and has limited solubility in alcohol; insoluble in water.

Pyrene is a constituent of the anthracene fraction in coal tar; it can be obtained from coal tar and petroleum cracking products. It is the raw material for the preparation of certain semifinished products in the manufacture of polycyclic dyes—for example, 3-nitropyrene, tetrachloropyrenequinone, and naph-thalene-l,4,5,8-tetracarboxylic acid.

Under these circumstances, our work will attempt to discern between the effects of the monomer structure in light-induced polymerization systems by using UV/visible light, the latter being easier to manipulate the cure properties of the composite resins, in which a pyrene molecule was incorporated as an optical probe.

Some examples are blood lead for lead exposure, carboxy haemoglobin for exposure to CO, and 1-Hydroxy pyrene for exposure to Polycyclic Aromatic Hydrocarbons (PAHs) to predict the health effects associated with exposure to these substances.

Soxhlet extraction led to a relatively better recovery of heavier PAHs (chrysene, pyrene and benzofluoranthenes) than ultrasonic extraction, whereas for the lighter PAHs recovery was not so good.
