3-Methyldiphenylether (MDE) is an important alkyl-substituted diphenyl ether compound that is widely used as an intermediate in the synthesis of pyrethroid insecticides. An efficient MDE-degrading strain QY7-2, identified as Hydrogenophaga atypical, was isolated from activated sludge for the first time. Strain QY7-2 can utilize MDE as the sole carbon and energy source and completely mineralize ...

Developing of novel, sustainable, and cost-effective antimicrobial substances is a global challenge. Our study on new bis(trifluoromethylsulfonyl)imide salts has led to environmentally benign pathways process room-temperature ionic liquids (RTILs) with alkoxymethyl substituent. The (containing small number steps), carried out under mild conditions easily available substrates, produced high yiel...

We have isolated a mixed bacterial culture (BC-1) which is capable of degrading the gasoline oxygenate methyl t-butyl ether (MTBE). BC-1 was developed from seed microorganisms present in a chemical plant biotreater sludge. This enrichment culture has been maintained in continuous culture treating high concentrations of MTBE (120 to 200 mg/liter) as the sole carbon source in a simple feed contai...

The title compound, C(28)H(24)N(2)O(5), a flexible Schiff base ligand, was prepared in high yield by a Schiff base condensation of 3-methoxy-salicylaldehyde and bis-(4-amino-phen-yl) ether in methanol. The mol-ecule lies on a twofold rotation axis, and each half exhibits an imine E configuration and an O-H⋯N hydrogen bond. The dihedral angle between the two benzene rings attached to the central...

The mol-ecule of the title compound, C(20)H(20)N(2)O(6), lies across a crystallographic inversion centre, the asymmetric unit comprising one half-mol-ecule. An intra-molecular O-H⋯N hydrogen bond generates a six-membered ring, producing an S(6) ring motif. Pairs of inter-molecular C-H⋯O hydrogen bonds link neighbouring mol-ecules into a layer with R(2) (2)(38) ring motif. The crystal structure ...

A new dimethacrylate monomer 9,9'-bis[4-(2'-hydroxy-3'-methacryloyloxy-propoxy)phenyl] fluorene (3) with a molecular weight of 634 was synthesized in 51.4% yield by addition of a glycidyl ether group to 9,9'-bis(4-hydroxyphenyl) fluorene (1) by the reaction of compound 1 with epichlorohydrin, and then introducing the methacrylate moiety by the reaction of the epoxy group with methacrylic acid. ...

The inhibition properties of synthesized imine compounds N,Nʹ-bis(2,4-dihydroxyhydroxybenzaldehyde)-1,3-Propandiimine, N, N′-bis(2,4-dihydroxypropiophenone)-2,2-dimethylpropandiimine, N,Nʹ-bis(2,4-dihydroxyacetophenone)-1,3-Propandiimine has been investigated for API-5L-X65 steel corrosion in hydrochloric acid by scanning electron microscopy, potentiodynamic polarization and impedance spectrosc...

In the mol-ecule of the title compound, C(14)H(16)N(2)O(3), the dihedral angle between the pyridyl rings is 87.74 (3)°. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into infinite zigzag chains.

A new series of 1:2 adducts of bis(s-alkylTrithiocarbonato)copper (where alkyl= ethyl, isopropyl and tertiarybutyl) have been prepared by reacting bis(s-alkyltrithiocarbonato)copper(II) with oxygen donor ligands. The resulting adducts have been characterized by elemental analysis, molar conductance, magnetic susceptibility measurement, biological studies, IR and UV-visible spectral studies. Ana...

Alkynes and olefins insert into [(IPr)CuH] 2 (IPr = N,N-bis-(2,6diisopropylphenyl)-1,3-imidazol-2-ylidene) to give copper vinyl and copper alkyl complexes. These copper complexes insert CO2 into the Cu-C bond to form copper acrylate and copper carboxylate complexes. Acrylic and carboxylic acids can be isolated
