Chemiluminescent mixtures utilize mono and di-alkyl substituted 9,10-bis(phenylethynyl)anthracene derivatives to provide higher chemiluminescence efficiencies. The preferred fluorescers are 2-ethyl-9,10-bis(phenylethynyl)anthracene and 1,4-dimethyl-9,10-bis(phenylethynyl)anthracene.

Chemiluminescent systems

Catalysts for low temperature hydrogen peroxide/oxalate ester fluorescer miluminescent systems are disclosed. Lithium carboxylic said salt catalysts which lower the activation energy of the reaction and also reduce the temperature dependence of the light emission process are preferred.

Chemiluminescent system catalysts

1,1,4,4-Tetrakis(trifluoromethyl)butan-1,4-diol and 1,1-bis (trifluoromethyl)propanol-1 are prepared by reacting gaseous hexafluoroacetone and ethane in a transparent container in the presence of sunlight. The diol is a crystalline solid and the propanol-1 is a liquid. The diol is useful as a monomer in the field of polymer chemistry. That is, polymers such as polyurethans and polyesters which find many applications in the chemical industry can be made by reacting the proper material with the diol of this invention. The propanol-1 is useful as a plasticizer for polyurethans and other plastics.
