Turner’s yellow

Several oxyohlorids are known. Cassel, Paris, Verona, or Turner s yellow is PbCla, 7PbO. 

Heaton (1928) lists Cassel yellow as an obsolete or rarely used pigment synonymous with Turner s yellow (lead chloride oxide q.v).

Synonyms hsted in the Salter edition of Field s Chromatography (1869) are patent yellow. Turner s yellow, MontpeUier yellow and Cassel yellow, all of which typically refer to lead chloride oxide friis identification is essentially repeated by Heaton (1928), although that author indicates that the term is obsolete or rarely used.

Lead dichloride occurs in nature as the mineral cotunnite. The compound is used in making many basic chlorides, such as Pattison s lead white. Turner s Patent Yellow, and Verona Yellow, used as pigments. Also, it is used as a flux for galvanizing steel as a flame retardant in nylon wire coatings as a cathode for seawater batteries to remove H2S and ozone from effluent gases as a sterilization indicator as a polymerization catalyst for alpha-olefins and as a co-catalyst in manufacturing acrylonitrile.

Ring-opening metathesis polymerization (ROMP) of substituted bicyclo octa-dienes or paracyclophane-enes initiated by Gmbbs molybdenum, tungsten-based carbenes have been used to prepare PPV s [178—181]. The living character of ROMP has been exploited to prepare soluble well-defined precursors, which can be converted into XI. Yu and Turner have used ROMP of tetra octyloxy-substituted paracyclo-phanedienes initiated by reactive ruthenium-based carbenes to prepare monodisperse, soluble yellow fluorescent PPV with an alternating cis-trans microstructure and molecular weights as calculated [178] (Fig. 9.21).
