Abstract
Procédé de préparation de composés de xanthénium asymétriques par reaction de composes d'acide phényl-9 xanthydrol-sulfonique-2' renfermant en position 3,6 des atomes ou des groupes d'atomes interchangeables et pouvant renfermer encore d'autres substituants dans le noyau benzénique qui porte le groupe d'acide sulfonique, avec des amines aromatiques primaires ou secondaires, dans un solvant polaire et à temperature élevée, procédé caractérisé en ce que la réaction est effectuée dans le domaine fortement acide. Les composés ainsi obtenus sont très purs, les réactions secondaires étant négligeables.
