Structure−function studies of naphthalene, phenanthrene, biphenyl, and their derivatives in interaction with and oxidation by †laboratory of cellular and molecular biology, graduate school of life and environmental sciences, osaka prefecture university, hplc separation was done with a jasco system (tokyo, japan) equipped with a.

Nitration of naphthalene nitration of naphthalene wed 2/25/2015 lab report # 1 abstract: the purpose of this experiment was to nitrate naphthalene with nitronium ion, which is formed at low concentration from a reaction of nitric acid and sulfuric acid the percent yield from the experiment was 544% of the product, and the melting point of the possible results were 59 °c for 1-nitronaphthalene, and 78°c for 2-nitronaphthalene. Napthalene and biphenyl mixture is a binary mixture of substances where the substances are very similar to each other as can be observed from their structures due to their similarities in physical properties their separation cannot be accomplished by simple crystallisation solvent extraction.

It was concluded that the naphthalene (50 % w/w) and biphenyl mixture was separated and the separation involved the formation of a derivative of naphthalene, a solid napthalene picrate, which was isolated from biphenyl. Abstract: naphthalene, phenanthrene, biphenyl, and their derivatives having different ethynyl, propynyl, butynyl, and propargyl ether substitutions were examined for their interaction with and oxidation by cytochromes p450 (p450) 2a13 and 2a6. Experiment 6 extraction a prelab assignment aqueous layer, but not allow for a clean separation of any one compound and naphthalene with aqueous sodium hydroxide will separate these compounds by drawing the benzoic acid, as its conjugate base, into the aqueous phase this is the principle behind this week’s experiment. The purity and purification of solids recrystallization abstract in this experiment, impure adipic acid is purified though recrystallization the impure.

Amino acid substitutions at asn-201, phe-202, val-260, trp-316, thr-351, trp-358, and met-366 had little or no effect on product formation with naphthalene or biphenyl as substrates and had slight but significant effects on product formation from phenanthrene. Then separation of the derivative from the mixture and finally the derivative is transformed back from the mixture it is noted that although the napthalene and biphenyl are two extremely similar chemicals, the naphthalene is a lewis base that reacts with picric acid to form a picrate however, biphenyl does not.
