Benzene is an acute as well as a chronictoxicant. The acute toxic effects from inhalation,ingestion, and skin contact are low tomoderate. The symptoms in humans are hallucination,distorted perception, euphoria, somnolence,nausea, vomiting, and headache. Thenarcotic effects in humans may occur from...
Our results are in accordance with this notion. Although we found associations between NO x concentration and the risks for some cancers, NO x is an indicator of vehicle engine exhaust, which is a c...R. Duarte-Davidson, C. Courage, L. Rushton, L. Levy, Benzene in the e...
1,2,4-Trimethylbenzene (mesitylene) is an aromatic hydrocarbon compound commonly present in commercial solvents encompassing their boiling range. Mesitylene are the most common isomer used in commercial applications. Aromatic hydrocarbons in hydrocarbon solvents are predominantly alkylated one ring structures...
It is estimated that 5280 coal burning stoves per square kilometre are used for cooking in Calcutta. The median concentration of benzene, toluene and xylene in the smoke plume above the coal burning stove used for cooking, was found to be 5497 g m3, 4080 g m3, and 962 g m3 respectively...
Benzene has a chemical shift of 128.5 ppm and the 1-, 2- and 4a-positions of naphthalene have shifts of 128.0, 126.0 and 133.7 ppm, respectively. Well defined substituent effects on aromatic carbon shifts in benzene derivatives have been derived. These are calculated according to the equation ...
River die-away tests have shown linear alkylbenzenes are readily biodegradable, with half-lives of 4.8 and 10.1 days for C-12 alkyl chain isomers in river water(8).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), ...
quality is being addressed, indoor environments are critical due to simultaneously the amount of time individuals spend indoors (between home, workplaces, visits to public spaces, school, etc., Kotzias estimated to be more than 85% of the day) and the concentration accumulate of air pollutants....
It is obtained by sulfonation and neutralization of heavy alkylbenzene by-product from the alkylbenzene plant. The double membrane sulfonation method is as follows. First, the metered SO3 gas and dry air are mixed in the mixer to a SO2 concentration of 4% (volume), and then the mixed gas...
reduction of benzoyl chloride in the laboratory. The main current preparation route is liquid chlorination or oxidation of toluene. The preparation methods that are eliminated include incomplete oxidation of benzyl alcohol, alkaline hydrolysis of benzoyl chloride, and addition of benzene and carbon ...
