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 |
