4.Production method of 1-Tetralone

1,2,3,4-tetrahydro-naphthalene could react to produce 1-Tetralone. This reaction could happen in the presence of the reagent of N-hydroxyphthalimide and the solvent of pyridine in the condition of anodic oxidation.

5.Uses of 1-Tetralone

1-Tetralone could react with indole-2,3-dione to produce 5,6-dihydro-benz[c]acridine-7-carboxylic acid. This reaction could happen in the presence of the reagent of aqueous-alcoholic alkali.

As to its usage, it is widely applied in many ways. It could be used as the intermediate of pharmaceutics, such as being the intermediate of prophylactic 18-methylnorethindrone and also the Benayzepril; It could also be used as the solvent and plastic softener; Beside, it could be used as the intermediate in rodenticide.

6.Safety information of 1-Tetralone

For being a kind of harmful chemical which may cause damage to health, it is dangerous to our body if by inhalation, in contact with skin and if swallowed. Therefore, you should wear suitable protective clothing and then avoid contacting with skin and eyes. Besides, do not breathe gas/fumes/vapour/spray (appropriate wording to be specified by the manufacturer).
