Acid Catalysed Condesation of Phloroglucinol and Acetone-Kinetics and Mechanism
The kinetic study of the condensation reaction between phloroglucinol and acetone was investigated at 30, 35, 40 and 45±0.05 °C in 100% methanol. The hydrochloric acid concentrations used were 0.0261, 0.0364, 0.0577 and 0.0728 M. The reaction was investigated with and without a promoter, thioglycollic acid (TGA), and taking into account the functionality (h<e...
متن کاملEffect of Phloroglucinol and Resorcinol on the Clingstone Peach Polyphenol Oxidase-catalyzed Oxidation of 4-Methylcatechol.
Phloroglucinol and resorcinol are not substrates for clingstone peach (Prunus persica) polyphenol oxidase, but they react with 4-methyl-o-quinone, produced either enzymatically or nonenzymatically, to give an intense red or red-brown color with a maximal absorption at about 470 nanometers. Several colored products were isolated from an ethyl acetate extract of the reaction by two-dimensional th...
متن کامل5-(2'-oxoheptadecyl)-resorcinol and 5-(2'-oxononadecyl)-resorcinol, cytotoxic metabolites from a wood-inhabiting basidiomycete.
5-(2'-oxoheptadecyl)-resorcinol [structure: see text] and 5-(2'-oxononadecyl)-resorcinol [structure: see text] were isolated from fermentations of an imperfect basidiomycete. The structures of the compounds were determined by spectroscopic techniques. Both compounds exhibit cytotoxic effects against the human colon tumor cell lines COLO-320, DLD-1 and HT-29 and the human promyeloid leukemia cel...
