Title: New condensation products of the anthraquinone series and process for their manufacture
IPC: C09B1/42
Filed: 1958-08-05
Abstract: The invention comprises condensation products of the general formula <FORM:0898535/IV (b)/1> in which A represents a mono- or divalent radical of the anthraquinone series, including anthrapyrimidine-1 : 9, which is substituted in one or two a -positions by the group (NH-CO-B-OPOCl2) and which may be further substituted by halogen atoms, alkyl, aryl, hydroxyl, alkoxy, aryloxy, nitro, amino, alkylamino, arylamino, dialkylamino and for acylamino groups, B represents a divalent radical of the benzene or naphthalene series and n represents the number 1 or 2, and a process for the manufacture of condensation products of the anthraquinone series including anthrapyrimidine-1 : 9, wherein an amino or diamino anthraquinone or an amino or diamino anthrapyrimidine-1 : 9 which may be substituted by halogen atoms, alkyl, aryl, hydroxyl, alkoxy, aryloxy, nitro, amino, alkylamino, arylamino, dialkylamino and/or acylamino groups, is reacted with an aromatic carboxylic acid chloride containing a phosphoric acid dichloride group at ordinary or raised temperature optionally in the presence of an inert solvent.  The examples relate to the preparation of chlorobenzene 4-(41-phosphoric acid dichloride-benzoylamino)-1-methoxy-, 1,5-di-(31phosphoric acid dichloride-benzoylamino)-, 4-(21-methyl-51phosphoric acid dichloride benzoylamino-1-hydroxy-, 1-amino-4-(31 - phosphoric acid dichloride - 1 - naphthoyl - amino-)-, 1 : 4 : 5 : 8-diamino-di-(21chloro-51 phosphoric acid dichloride-benzoylamino)- and 1 : 8-dihydroxy-4-amino-5-(41-phosphoric acid dichloride-benzoylamino)-anthraquinones and 5-(41-phosphoric acid dichloride-benzoylamino)-1 : 9-anthrapyrimidine.ALSO:The invention comprises condensation products of the general formula A-(NH-CO-B-OPOCl2)n in which A represents a mono- or divalent radical of the anthraquinone series, including anthrapyrimidine 1 : 9, which is substituted in one or two a -positions by the group (NH-CO-B-OPOCl2) and which may be further substituted by halogen atoms, alkyl, aryl, hydroxyl, alkoxy, aryloxy, nitro, amino, alkylamino, arylamino, dialkylamino and/or acylamino groups, B represents a divalent radical of the benzene or naphthalene series and n represents the number 1 or 2 and a process for the manufacture of condensation products of the anthraquinone series including anthrapyrimidine-1 : 9, wherein an amino- or diamino anthraquinone or an amino or diamino anthrapyrimidine-1 : 9 which may be substituted by halogen atoms, alkyl, aryl, hydroxyl, alkoxy, aryloxy, nitro, amino, alkylamino, arylamino, dialkylamino and/or acylamino groups, is reacted with an aromatic carboxylic acid chloride containing a phosphoric acid dichloride group optionally in the presence of an inert solvent. The examples relate to the preparation of chlorobenzene 4-(41-phosphoric acid dichloride-benzoylamino) - 1 - methoxy -, 1, 5 - di - (31-phosphoric acid dichloride-benzoylamino)-, 4-(21-methyl-51-phosphoric acid dichloride benzoylamino-1-hydroxy-, 1-amino-4-(31-phosphoric acid dichloride-1-naphthoyl-amino-)-, 1 : 4 : 5 : 8-diamino - di - (21 - chloro - 51 - phosphoric acid dichloride-benzoylamino)- and 1 : 8-dihydroxy - 4 - amino - 5 - (41 - phosphoric acid dichloride-benzoylamino)-anthraquinones and 5-(41phosphoric acid dichloride-benzoylamino)-1 : 9-anthrapyrimidine.
