The removal characteristics of para-nitrophenol from aqueous solution by fly ash were investigated under various conditions of contact time, pH and temperature. The influence of pH on the para- nitrophenol uptake by the fly ash was carried out between pH4 and pH 10. The level of uptake of para- nitrophenol by fly ash
19 Dec 2017 On Aug 31, 2013, Nobutada Kimura (and others) published the chapter: Biodegradation of Nitrophenol Compounds in the book: Biological remediation of Explosive Residues.
This Statement was prepared to give you information about 2-nitrophenol and 4-nitrophenol and to emphasize the human health effects that may result from exposure to them. The Environmental Protection Agency (EPA) has identified 1,177 National Priorities List (NPL) sites. Nitrophenols have been found at 14 of these

4-Nitrophenol is used to manufacture drugs, fungicides, insecticides, and dyes and to darken leather. Acute (short-term) inhalation or ingestion of 4-nitrophenol in humans causes headaches, drowsiness, nausea, and cyanosis (blue color in lips, ears, and fingernails). Contact with eyes causes irritation in humans.
With the exception of 2,6-diiodo-4-nitrophenol, the materials were commercial products. I am indebted to Dr. Marion M. Davis for the following details of their purification. 2-Chloro-4, 6-dinitrophenol was recrystallized twice from benzene-cyclohexane, mp 111.0- 111.5 0c. 4-. Chloro-2,6-dinitro-3-methylphenol was
NITROPHENOLS. CAS # 88-75-5 and 100-02-07. Agency for Toxic Substances and Disease Registry ToxFAQs. September 1995. SUMMARY: Everyone is exposed to very low levels of the nitrophenols in air, water, and soil. Workers who make or process the chemicals may be exposed to higher levels of them. Animal
peptide synthesis (eq 1).1 They are readily purified by re- crystallization, often from alcoholic solvents with which they do not react. Aminolysis occurs at a reasonable rate, generally at room temperature without a catalyst. The p-nitrophenol gener- ated as a byproduct in this step is easily removed. o-Nitrophenyl esters can be
7 Mar 2018 Full-text (PDF) | The mol-ecule of the title compound, C(7)H(7)NO(3), is nearly planar [maximum deviation 0.112 (3) A for one of the notro O atoms]. In the crystal structure, inter-molecular O-H?O and C-H?O inter-actions link the mol-ecules into a three-dimensional network.
