Book excerpt: Various oxalate esters have been synthesised and their chemiluminescent emission examined in an attempt to produce an improved low intensity, disposable lighting device suitable for 10 hours operation. Derivatives of the bis(2-carboalkoxy-4,6-dinitrophenyl)oxalate series were shown to possess unsuitable stability while the chemiluminescence of the bis(6-carboalkoxy-2,4,5-trichlorophenyl)oxalates was too intense to modify suitably. A number of bis(6-carboalkoxy-2,4-dichlorophenyl)oxalates were prepared and by treatment with various combinations of catalyst and inhibitor satisfactory low intensity light emission could be achieved after a 5 minute induction period. Optimum conditions were: oxalate ester, 2 x 10( -2)M; H2O2, 2 x 10( -2)M; potassium salicylates, 5 x 10( -4M); oxalic acid, 10( -4M). The storage stabilities and solubilities of the dichloro series of oxalates were superior to those of 2,4,6-TCPO. Aspects of the synthesis of the substituted salicylic acid precursors to the oxalates are discussed. The merits of chemiluminescent systems relative to beta lights are considered for the particular case of low level illumination. (Author).
