Description

Application

1-Methylnaphthalene defines the lower (zero) reference point of cetane number, a measure of diesel fuel ignition quality, as it has a long ignition delay (poor ignition qualities)
The 1-Methylnaphthalene may find the following uses:

• Study of surface and electronic features of fluorinated TiO2 and their influence on the photocatalytic degradation of 1-methylnaphthalene
• Thermal decomposition of 1-Methylnaphthalene in a batch reactor
• Catalytic conversion of tar from hot coke oven gas using 1-methylnaphthalene as a tar model compound
• Hydrocracking of 1-methylnaphthalene to benzene, toluene, and xylene using high metal–acid balance and selective hydrogenation activity catalysts
