Abstract:
Bis(p-alkylphenylethynyl)anthracenes are described for use as fluorescer components in chemiluminescent reaction mixtures and in precursor solutions or solid mixtures. Chemiluminescent mixtures comprising these fluorescers are shown to generate higher light capacity and higher quantum yields than those made with similar prior art fluorescers.

Abstract:
An improved single-pot process for synthesis of 3,5,6-trichlorosalicylic acid and esters thereof is described. Salicylic acid is chlorinated first in concentrated sulfuric acid and then with iodine catalyst to make the trichlorosalicylic acid which is extracted and then reacted with an alcohol to make the ester.
