The photochemistry of 1-(4-methylphenyl)-3-phenyl-2-propanone (MeDBK) in polyethylene (PE) films of varying crystallinity and at different temperatures has been investigated. Specifically, the selectivity of combination of the initially formed triplet pairs of benzylic radicals derived from
In the title compound, K[Ni(C(3)S(5))(2)] x C(20)H(24)O(6).C(3)H(6)O, K(+) is incorporated in the cavity of the 1,4,7,10,13,16-hexaoxa-2,3:11,12-dibenzocyclooctadeca-2,11-diene (DB18c6) molecule and is coordinated by the six DB18c6 O atoms and the propanone O atom. Two [K(+)(DB18c6)[(CH(3))(2)CO]]
The compound CH-401-Na (1-[2-hydroxy-4-(3-sulphopropyloxy)phenyl]-3-[3-hydroxy-4-methoxyphenyl]-propanone-1-Na) was studied. Its sweeting power in aqueous solution is 1000 (as compared to that of a 1% sucrose solution); the values for salts formed with 10 other cations range from 750 to 1150. In
