| 1-Methylnaphthalene Usage And Synthesis |
| Description | 1-methylnaphthalene is a methylnaphthalene carrying a methyl substituent at position. It is a polycyclic aromatic hydrocarbon (PAH). It is present in cigarette smoke, wood smoke, tar, asphalt, and at some hazardous waste sites. The main use of 1-methylnaphthalene is as a raw material for naphthoic acid, fluorescent whitening agents, and surfactants. It is also used as a raw material for dyestuff dispersants and heat transfer oils, and as a solvent for agricultural chemical. |
| Chemical Properties | 1-methylnaphthalene is a colorless, bluefluorescing liquid with an earthy, phenolic odor. It is insoluble in water but dissolves in alcohol and ether. With a density greater than water, this combustible substance is obtained from coal tar and used in organic synthesis. It has a role as a carcinogenic agent and a plant metabolite. |
| Occurrence | Methylnaphthalene was identified as a volatile component of cassava, roasted filberts and nectarines. Assorted types of lima, pinto, red kidney, black, navy and mung beans, soybeans, split peas and lentils were found to contain 1-methylnaphthalene at concentrations ranging from 2.8 to 49.2 ppb. |
| Uses | The main uses of methylnaphthalene are as a raw material for dyestuff dispersants and heat transfer oils, and as a solvent for agricultural chemical. It is used in insecticide manufacturing; manufacture of phthalic anhydride; solvent in organic synthesis; asphalt and naptha constituent. It is also used as a test substance for the determination of the cetane number of diesel fuels. Further, it is employed in the preparation of 1-methylnaphthalene-d10 using deuterium oxide, sodium deuteroxide. |
| Definition | ChEBI: 1-methylnaphthalene is a methylnaphthalene carrying a methyl substituent at position 1. It has a role as a carcinogenic agent and a plant metabolite. |
| Preparation | 1-Methylnaphthalene is primarily derived from coal tar and petroleum oils. It is present in high-temperature coal tar in a concentration of 0.5% and is produced industrially from the methylnaphthalene fraction, which boils between 240 and 245 °C, by redistillation of the 2-methylnaphthalene filtrate following crystallization and separation of 2-methylnaphthalene. |
