Background During the lab experiment, we are going to place the Naphthalene on the gauze mat which will be kept above the Bunsen burner using a retort stand.
1-Methylnaphthalene is an organic compound with the formula CH3C10H7.
It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. Solubility in methanol/ethanol: 7.7g/100mL Very soluble in ether.
Naphthalene in air will be broken down by moisture and sunlight, often within one day. Show More. MDL number: ... Melting Point Solubility Anal.
These studies suggest that the major enzymes involved in the metabolic activation of naphthalene or 2-methylnaphthalene in vitro are the cytochrome P-450 monooxygenases and that cooxidative metabolism by the prostaglandin synthetases appears to play little … Boiling point : 217.9°C Melting point : 80.2°C Flash point - open cup 79°C closed cup 88°C Autoignition temp: 567°C Vapour pressure (at 25°C): 0.087 torr Solubility in water, alcohol and ether - Solubility in water: 3mg/100mL at room temperature.
