Title:
METHOD FOR PRODUCTION OF 5-NITRO-3, 4-DIHYDRO-1(2H)-NAPHTHALENONE, 1, 5-NAPHTHALENEDIAMINE AND 1, 5-NAPHTHALENE DIISOCYANATE
Document Type and Number:
Japanese Patent JP2004010613
Kind Code:
A
Abstract:
To provide a method for production of 5-nitro-3, 4-dihydro-1(2H)-naphthalenone, 1, 5-naphthalenediamine and 1, 5-naphthalene diisocyanate.
The producing method comprises a step converting 4-(2-nitrophenyl)-n-butyronitrile to 4-(2-nitrophenyl)-n-butyric acid. The method does not produce a remarkable amount of other isomers and does not require isolation of the isomer.
