the aims of this study were to determine hippuric acid and toluene in urine samples, airborne toluene levels, health effects, and to describe any correlation between specimen samples. seventy-five printing workers exposed to toluene at work (exposed group), and 60 nonexposed people (control group) were studied. study participants were selected from same factories in the different positions. uri...
The amination of aryl halides in the presence of inexpensive and air-stable alkali metal hydroxide bases and Pd[P(t-Bu)3]2 as catalyst gave arylamines in high yields. The reactions were conducted with a catalytic amount of cetyltrimethylammonium bromide as phase-transfer agent and either aqueous hydroxide or solid hydroxide in the presence of water. This combination of alkali metal hydroxide ba...
In the title compound, C(18)H(13)NO(8)S(2), the nitro-phenyl ring forms dihedral angles of 46.67 (7) and 75.40 (6)° with the phenyl rings. The nitro group makes a dihedral angle of 26.13 (8)° with the attached ring. The crystal packing is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
Toluene-o-xylene monooxygenase (ToMO) from Pseudomonas stutzeri OX1 was found to oxidize nitrobenzene (NB) to form m-nitrophenol (m-NP, 72%) and p-NP (28%) with an initial rate of 0.098 and 0.031 nmol/(min mg protein), respectively. It was also discovered that wild-type ToMO forms 4-nitrocatechol (4-NC) from m-NP and p-NP with an initial rate of 0.15 and 0.0082 nmol/(min mg protein), respective...
Pseudomonas mendocina KR1 grows on toluene as a sole carbon and energy source. A multicomponent oxygenase was partially purified from toluene-grown cells and separated into three protein components. The reconstituted enzyme system, in the presence of NADH and Fe2+, oxidized toluene to p-cresol as the first detectable product. Experiments with p-deutero-toluene led to the isolation of p-cresol w...
Construction of a hybrid strain which is capable of mineralizing components of a benzene, toluene, and p-xylene mixture simultaneously was attempted by redesigning the metabolic pathway of Pseudomonas putida. Genetic and biochemical analyses of the tod and the tol pathways revealed that dihydrodiols formed from benzene, toluene, and p-xylene by toluene dioxygenase in the tod pathway could be ch...
Abstract The removal of organic pollutants from ship emission was studied using two processes namely electron beam (EB) and hybrid EB with wet scrubbing process. A mobile accelerator unit used to treat 4915 Nm 3 /h flue gas emitted a tugboat in Riga Shipyard. volume m seawater containing 36.8 mM NaClO 2 oxidant as scrubber solution. Organic pollutants, mainly volatile (VOCs), were collected at ...
