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.

CATALYTIC CONVERSION OF ALCOHOLS HAVING AT LEAST THREE CARBON ATOMS TO HYDROCARBON BLENDSTOCK

A method for producing a hydrocarbon blendstock, the method comprising contacting at least one saturated acyclic alcohol having at least three and up to ten carbon atoms with a metal-loaded zeolite catalyst at a temperature of at least 100°C and up to 550°C, wherein the metal is a positively-charged metal ion, and the metal-loaded zeolite catalyst is catalytically active for converting the alcohol to the hydrocarbon blendstock, wherein the method directly produces a hydrocarbon blendstock having less than 1 vol% ethylene and at least 35 vol% of hydrocarbon compounds containing at least eight carbon atoms.

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.

INTRODUCTION OF METHYL GROUPS INTO POLYCYCLIC COMPOUNDS THROUGH THE PHOSPHONIUM SALTS OF METHYLNAPHTHALENE AND 9-METHYLPHENANTHRENE

Chloromethyl derivatives synthesized by the chloromethylation of naphthalene and methylnaphthalenes were converted into the corresponding triphenylphosphonium salts.Alkaline hydrolysis of the latter gave 1-methylnaphthalene and some di-, tri-, and tetramethylnaphthalenes. 9-Methylphenanthrene was obtained similarly from phenanthrene.The corresponding diarylethenes were synthesized from the phosphonium salts by the Wittig reaction.
