12. Finding Juliet Blue

Michael Thomas Butler University
Faculty Sponsor(s): Anne Wilson Butler University
The National History Museum in Verona, Italy improperly stored their prehistoric flints. The rubber mats in the storage compartment gave off the compound 2,2,4-trimethyl-1,2-dihydroquinoloine which we believe formed a film that stained the flints a peculiar blue known as Juliet Blue. My research entails recreating the same or similar conditions in the National History Museum by undergoing gas reactions involving formaldehyde and 2,2,4-trimethyl-1,2-dihydroquinoloine to see the colorful results plastered on silica gel. By recreating the same conditions I have been able to learn more about the reaction that tinted the flints Juliet Blue. I am also using similar reaction conditions to produce similar compounds such as Hofmann Violet and Helvetia Green to gather more information on the possible mechanism of creating these dyes.
