    Aryl-Δ2-pyrazoline als optische Aufhellungsmittel (1966)
    Weinheim : Wiley-Blackwell
    Zeitschrift für die chemische Industrie 78 (1966), S. 769-774 
    Details
    ISSN: 0044-8249

    Topics: Chemistry and Pharmacology
    Notes: Di- und Triaryl-Δ2-pyrazoline sowie ihre Derivate können als optische Aufhellungsmittel für synthetische Fasern und Kunststoffe verwendet werden. Diese Heterocyclen sind nach mehreren Methoden gut zugänglich, z. B. durch Kondensation von β-Halogen- oder β-Dialkylamino-propiophenonen mit Phenylhydrazin. Zwischen Substitution und optischen Eigenschaften lassen sich einige Beziehungen feststellen.

    Aryl-Δ2-pyrazolines as Optical Brighteners (1966)
    Weinheim : Wiley-Blackwell
    Angewandte Chemie International Edition in English 5 (1966), S. 699-704 
    Details
    ISSN: 0570-0833
    Keywords: Optical brighteners ; Pyrazoles ; 4,5-Dihydro-1H-pyrazoles ; Chemistry ; General Chemistry

    Topics: Chemistry and Pharmacology
    Notes: Di- and triaryl-Δ2-pyrazolines and their derivatives can be used as optical brighteners for synthetic fibers and plastics. The heterocycles are readily obtainable by several methods, e.g. condensation of β-halogeno- or β-dialkylaminopropiophenones with phenylhydrazine. A number of relationships can be detected between substitution and optical properties.
