General Description

1,4,5-Trimethylnaphthalene is a chemical compound that belongs to the polynuclear aromatic hydrocarbons (PAHs) group with the CAS number 877-56-1. It is a derivative of naphthalene, characterized by its strong, odoriferous smell, and it's synthesized from coal tar naphthalene. 1,4,5-TRIMETHYLNAPHTHALENE appears as a light straw-colored liquid. Several safety protocols need to be followed when handling this chemical due to its flammability and potentially harmful effects if it comes in contact with the skin or eyes, or if ingested or inhaled. It is used in various industrial applications, particularly in the production of dyes, resins, and other chemical compounds.

Photooxidation of methylnaphthalenes

(Chemical Equation Presented). Studies on the photooxidation of methyl-substituted aromatic hydrocarbons have revealed that whereas electron density is a determinant of endoperoxide formation, steric factors are most important in influencing the stability of the endoperoxide. Additional information on the energetics of the reactions and on the magnitude of the steric interactions was obtained using calculations at the B3LYP/6-311+G* level of theory.

Synthesis of renewable alkylated naphthalenes with benzaldehyde and angelica lactone

Herein, we report a new route for the synthesis of renewable alkylated naphthalenes (ANs) with benzaldehyde and angelica lactone, two platform compounds that can be derived from lignocellulose.

Evolution of products in the combustion of scrap tires in a horizontal, laboratory scale reactor

A horizontal laboratory reactor was used to study the evolution of byproducts from the combustion of scrap tires at five nominal temperatures (ranging from 650 to 1050 °C) and different oxygen:sample ratios A model was used to calculate the bulk air ratio (λ), and the oxygen consumption was discussed considering this ratio λ. More than 100 volatile and semivolatile compounds were identified and quantified by gas chromatography mass spectrometry, plotting their yields vs the bulk air ratio and temperature. Five different behaviors considering the bulk air ratio and the temperature were identified.
