Related Products of 93-04-9, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 93-04-9, name is 2-Methoxynaphthalene belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
A solution of bromine (first raw material storage tank 1) and 2-methoxynaphthalene in acetic acid (2-methoxynaphthalene in acetic acid solution(Second raw material storage tank 2) was successively passed through a microstructured mixer according to a molar ratio of 2-methoxynaphthalene and bromine of 1: 33,A heat exchanger 4,A tubular temperature control module 5 and a first microstructure reactor 6,In the first microstructure reactor 6Pressure and 55 C to stay 8. 5min reaction.at the same time,The first microstructure reactor 6 discharges the second microstructure reactor 7,In a second microstructure reactor 7 at atmospheric pressure and 85 C for 8 min,The second microstructure reactor 7 is discharged through a length of polytetrafluoroethylene capillary into the product collecting bottle 8,The polytetrafluoroethylene capillary was immersed in an ice-water bath to terminate the reaction.The second microstructure reactor is introduced into the ice water,A large number of solid precipitation,Filtration,Washed,The filter cake was dissolved in chloroform, washed with 10wt% Na0H aqueous solution, washed with water, dried over anhydrous sodium sulfate and evaporated to chloroform. The residue was recrystallized from anhydrous ethanol to give white needle crystals in a yield of 90.2% .
The synthetic route of 2-Methoxynaphthalene has been constantly updated, and we look forward to future research findings.
