WebOn the other hand, the flash point of a mixture of chemically related solvents lies between those of the individual components [14.87]-[14.89]. Methods have been developed for calculating the flash point of solvent mixtures and solutions, activity coefficients are used to account for nonideal behavior [14 WebAbstract— The photoreduction of riboflavin, FMN, and lumiflavin in a series of hydroxylic solvents has been examined using flash photolysis. A comparison of the relative quantum yields for the photoxidation of several alcohols and esters by lumiflavin demonstrated that the hydroxyl hydrogen of the alcohol is abstracted approximately twice as ...
