These effects will decrease the alkylating ability of the modified MAO at the stage of pre-catalyst activation, resulting in the rapid decline of activity with the increasing dosage of naphthols. Of cause, the reactions between naphthols and MAO are very complicated, it is also reasonable that the naphthols would cause the structure re-arrangement, collapse or decomposition of MAO.
The synthesis of 2,3-dihydro- 1H-naphtho[1,2e]-, 3,4-dihydro-2H-naphtho[2,1-e][1,3]oxazines involves one-pot condensation cyclization reaction of naphthols with formaldehyde and primary amines.
Types of pigments: Blacks (carbon black), Blues (basic dye pigments, phthalocyanine, indanthrone, quinacridone, PMA, PTA, methyl, tungstated), Greens (phthalocyanine, PMA, PTA), Reds (toluidine, naphthol, anthanthrone, DPP, manganese 2B, bon maroon, lithol rubine, antrhaquinone, quinacridone, alizarin, lithol rubine, perylene, rhodamine, robine red, AZO complex, bisacetoacetarylide), Yellows and Oranges (mono azo, diarylide, benzimidazolone, dispersion, bismuth vanadate, proprietary, dianisidine, dinitroaniline, hansa, isoindolinone, isoindoline, quinophthalone, naphthol, bisacetoacetarylide)
Thirty-three phenolic compounds, predominantly phenol, alkyl phenol, thymol, naphthol and alkyl naphthol, were identified in the final enriched product.
The CB7/SY inclusion complex was further studied by molecular modeling calculations, and results indicated that the naphthol part of the SY molecule was included into the CB7 cavity.
Briefly, the MII oocytes were washed in phosphate-buffered saline supplemented with 5% BSA, then they were incubated in a solution containing 15 mg N-Phenyl-p-phenylene diamine (p-aminodiphenylamine), 15 mg naphthol AS-LG, 0.1 ml ethanol 100%, 50 ml tris-HCl buffer (pH=7.2-7.4) and 5 mg BSA/ml at 37[degrees]C for 60 min.

The azo dye coupling methods were used for acid phosphatase and alkaline phosphatase, with naphthol AS-BI phosphate and [alpha]-naphthol phosphate as substrates, and for non-specific esterases, with the substrates [alpha]-naphthyl acetate, naphthyl AS-D chloroacetate, and Tween-80 (DifCo), as described in Bancroft and Hand (1987).
(2010) reported 84 and 89.1 % decolorization of naphthol blue black and rodamin 6G in presence of vanillin and by pointed gourd peroxidase, respectively.
The Florida color lifetimes varied significantly depending on the pigment grade (a phthalo green pigment grade performed best and a naphthol red grade performed worst).
Molisch test: Alpha naphthol and concentrated [H.sub.2]S[O.sub.4] were added to 2 mL solution of the extract.
It is found to be so due to the -I effect of the substituted aromatic naphthol group which reduces the electron density of imine nitrogen.
BB with [sp.sup.3] hybridized carbon attached to phenyl ring, amine, and naphthol is expected to exhibit an interesting redox property.
