1(2H)-Naphthalenone, 3,4-dihydro-6,7-dimethyl- - Introduction
6,7-dimethyl-1-tetralone, also known as 2,3,4,5-tetrahydro-6,7-dimethylnaphthalene -1(4H)-One, chemical formula C12H16O. The following is an introduction to its nature, use, preparation and safety information:
Nature:
6,7-dimethyl-1-tetralone is a colorless to pale yellow liquid with a special aroma. It has a density of 0.976g/cm³, a boiling point of 224-225°C, and a flash point of 92°C. It is soluble in alcohol, ether and organic solvents, insoluble in water.
Use:
6,7-dimethyl-1-tetralone is mainly used as a fragrance and stabilizer to prevent pigment fading. It has a special aroma and is often used in perfumes, soaps and cosmetics, as well as in the food industry. In addition, it can also be used as a stabilizer in coatings, paints and inks to prevent pigment discoloration due to light or heat treatment.
Method:
The preparation method of 6,7-dimethyl-1-tetralone is mainly obtained by the oxidation reaction of tetrahydronaphthalene. A common preparation method is to heat-react tetrahydronaphthalene with oxygen in the presence of a catalyst, which may be a transition metal oxide or silver oxide, etc.
Safety Information:
6,7-dimethyl-1-tetralone is generally considered to be a low-toxic compound, but appropriate safety measures are still required. During use, skin contact and inhalation of its vapors should be avoided, and appropriate protective gloves and masks should be worn. If it comes into contact with skin or eyes, rinse immediately with plenty of water and seek medical attention. At the same time, it should be stored in a cool and dry place, away from fire and oxidizing agents.
