• Inhalation Risk: No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20 °C.
• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis.
• Effects of Long Term Exposure: The substance defats the skin, which may cause dryness or cracking.
• Uses: 1. Anisole is a solvent used in the synthesis of organic compounds and in large-scale applications such as the production of perfumes.2. GB2760-1996 stipulates it as allowable usable spices in food. It is mainly used for the preparation of vanilla, fennel and beer flavor.3. It is used for analyzing the reagents, solvents, and used for preparing perfumery and enteral pesticides.4. Anisole has been used directly in the synthesis of the marine pyrrole alkaloids polycitone A and B and the nonylphenol isomer 4-(3',6'-dimethyl-3-heptyl)phenol.5. It is used as solvents for recrystallization, fillers of thermostat, and used for measuring refractive index, as spices and organic synthesis intermediates. Anisole is widely used as a solvent for the synthesis of various organic compounds, anethole, nonylphenol isomer 4-(3',6'-dimethyl-3-heptyl)phenol, perfumes, insect pheromones and pharmaceuticals. It finds application in the preparation of inorganic complexes and materials such as tin-core/tin oxide nanoparticles.
• Production method: Anisole is produced through the reaction of methylating agent of dimethyl sulfate with phenol in alkaline aqueous solution. Phenol was mixed with sodium hydroxide solution, dimethyl sulfate was slowly added at below 10°C. And then heat to 40 °C, reflux for 18h, then stand for separation of the oil and dried with anhydrous calcium chloride, vacuum distillation to obtain anisole. It is derived by introducing the methyl chloride into the sodium phenol of liquid ammonia to react. It is generated from heating phenol and methanol. It is obtained from the reaction of phenol with dimethyl sulfate in the presence of sodium hydroxide.
