| abstract | 1,232,241. Preparation of phthalocyanine compounds. RANK XEROX Ltd. 28 .Tune, 1968 [3 July, 1967], No. 30958/68. Heading C4P. A process for the preparation of an organic pigment comprises (a) mixing an N-alkyl or di-alkyl-alkanolamine and a reactant selected from optionally substituted 1,3-di-imino-isoindolenine, a heterocyclic analogue of 1,3-diimino-isoindolenine or mixtures of these, (b) heating to reflux temperature, (c) maintaining this temperature for sufficient time to form the pigment preferably 10 mins.-7 hours. The preferred reactants include 2-dimethyl-aminoethanol, 1 - dimethylamino - 2 - propanol, 1 - di-ethylamino - 2 - propanol, and the 5-nitro-, 5-acetamido-, and 5-chloro-derivatives of 1,3-di-imino-isoindoline also the 4,5,6,7- tetrabromo derivative. Phthalocyanine pigments are produced. |
