METHOD FOR THE PRODUCTION OF PERYLEN-3,4:9,10-TETRACARBOXYLIC ACID DIIMIDES AND PERYLEN-3,4:9,10-TETRACARBOXYLIC ACID DIANHYDRIDE AND NAPHTALENE-1,8-DICARBOXYLIMIDES

摘要

Produce perylen-3, 4:9, the general formula (I) of the imidodicarbonic diamide of 10-tetracarboxylic acid, wherein R=C1-C30 alkyl, wherein carbochain can be by one or several-O- groups and/or by C5-C8 naphthenic base, it can be mono- or multiply-substituted by C1-C6 alkyl, phenyl or phenyl-C1-C6 alkyl, respectively can be it is single or multiple point displacement with C1-C18 C1-C6 alkyl and/or alkoxy, and mono- or multiply-substituted pass through-OCOR1,-n (R1) 2,-SO2NH2,-SO2N (R1) 2,-CON (R1) 2 and/or-COOR1; C5-C8 naphthenic base, wherein carbon skeleton can have C1-C6 alkyl by what one or more-O- ,-S- and/or-NR2- group and/or single or multiple point were replaced; Phenyl, phenyl-C1-C6 alkyl, naphthalene or heteroaryl, they can be it is single or multiple point displacement with C1-C18 alkyl, C1-C6 alkoxies, phenylazo, naphthylazo, pyridylazo, pyrimidylazo, cyano, n (R1) 2 ,-CON (R1) 2 and/or or-COOR1; R1 to C1-C6 alkyl, C5-C8 naphthenic base, phenyl or phenyl-C1-C6 alkyl; R2 to C1-C6 alkyl, phenyl or phenyl-C1-C6 alkyl, pass through dimerization naphthalene -1,8-dicarboximide formulas (II), thus the dimerization is that reaction medium basically comprises nonpolar aprotic organic solvent and alkali includes perylen-3,4:9 of alkali metal Yu above-mentioned leuco form, then acid precipitating 10-tetracarboxylic imidodicarbonic diamide reoxidizes in polar solvent as alkali metal salt. The present invention also relates to production perylen-3,4:9,10-tetracarboxylic acid anhydrides and naphthalene -1,8-dicarboximides.
