The removal performance of total poly phenols and orthodiphenols (o-diphenols) content in olive mill waste (OMW) was investigated with a three stages cross flow laboratory scale rotating biological contactor (RBC) in the present study. Due to high COD and other pollutant in the original OMW, physico-chemical treatment was effected for COD and other pollutant reduction prior to biological tr...

HCI in lOml of methanol and diluting to IOOml with butan-1-o1;just before use, 0.1 g of sodium dithionite was added. The dried electrophoresis sheets were sprayed with the reagent and developed at 120°C for 1 5min. With 4and 6-sulphated disaccharides a strong colour-positive reaction occurred with p-anisidine at the highest amount examined (20pg) and a detectable coloured product was observed a...

A bioassay for possible carcinogenicity of p-anisidine hydrochloride was conducted using Fischer 344 rats and B6C3F1 mice. p-Anisidine hydrochloride was administered in the feed, at either of two concentrations, to groups of 55 male and 55 female animals of each species. Fifty-five animals of each sex and species were placed on test as controls. The high and low dietary concentrations of p-anis...

Aromatic amines represent a category of classical environmental hazards which require biotransformation in order to exert their mutagenic and carcinogenic effects. The mutagenic activity of several aromatic amines was tested by means of the w/w+ somatic assay of Drosophila melanogaster employing a wild-type strain Leiden Standard (LS) and an insecticide-resistant stock Hikone-R (HK-R). Four mon...

The title compound, C(14)H(12)ClNO(2), was prepared by refluxing 4-chloro-benzoyl chloride with o-anisidine in CHCl(3). The methoxy-phen-yl-amide segment of the mol-ecule is almost planar, with a dihedral angle of 5.10 (7)° between the benzene ring and the C-N-C(O)-C fragment. A weak intra-molecular N-H⋯O contact forms an S(5) ring and contributes to the planarity of this portion of the mol-ecu...

This paper reports the isolation of phenoloxidase-negative mutants of the white-rot fungus Phanerochaete chrysosporium and the results of a survey of idiophasic functions among these mutants. The mutant strains were isolated from a medium containing o-anisidine after gamma irradiation of wild-type spores and fell into four classes, divided by the manner in which they mineralized 14C-lignin whea...

Makaluvamine C is a pyrroloiminoquinone which has been isolated from marine sponges. This molecule has been synthesized in 13 steps from p-anisidine. The key steps in this synthesis include an intramolecular nucleophilic aromatic substitution mediated by potassiumtert-butoxide, the selective reduction of a dinitro ester using catalytic hydrogenation, and the novel use of Fremy's salt to synthes...

The behavior of 2-ethoxy-(4H)-3,1-benzoxazin-4-one (1) towards nitrogen nucleophiles, e.g. ethanolamine, aromatic amines (namely: p-toluidine, p-anisidine, p-hydroxyaniline, o-hydroxyaniline, o-bromoaniline, o-phenylenediamine, p-phenylenediamine, o-tolidinediamine) p-aminobenzoic acid, glucosamine hydrochloride, 2-aminonicotinic acid, 1-naphthalenesulfonic acid hydrazide, n-decanoic acid hydra...
