1,9-DIPHENYL-1,3,6,8-NONATETRAEN-5-ONE Chemical Properties,Usage,Production
Chemical Properties
yellow powder
Uses
Dicinnamalacetone was used as an indicator in measuring the surface acidity of homoionic montmorillonites by titrating certain Hammett indicators adsorbed on the clay with n-butylamine. It was also used as an indicator (yellow to bright red) for detection of excess hydrogen halides in many organic solvents (except alcohols).
Purification Methods
Crystallise the ketone from *benzene/isooctane (1:1). The 1,3,5-trinitrobenzene complex (1:1) has m 113o (from EtOH), and the 1,3,5-trinitrobenzene complex (1:2) has m 110o (from EtOH). [Beilstein 7 H 524, 7 I 293, 7 II 484, 7 III 2756, 7 IV 1834.] The 2,4-dinitrophenylhydrazone has m 199-200o.
