In the title compound, C(20)H(17)NO(4), the double bond of the acrylonitrile group separating the 1-benzofuran moiety from the 3,4,5-trimeth-oxy-phenyl ring has Z geometry. The 1-benzofuran groups are π-π stacked with inversion-related counterparts such that the furan ring centroid-centroid distance is 3.804 (5) Å. The dihedral angle between the planes of the trimeth-oxy-phenyl ring and the acr...

The introduction of high molecular weight poly(methyI methacrylate) or poly(butadiene-co-acrylonitrile) into ethyl 2-cyanoacrylate produced viscous adhesives with a homogeneous or heterogeneous structure after cure. Steel joints bonded with these adhesives are shown to have improved tensile shear strength, deformability and stress relaxation of bonds compared with pure cyanoacrylate adhesive. P...

A series of new trimethoprim [5-(3,4,5-trimethoxy-benzyl)-pyrimidine-2,4- diamine] analogues were prepared by condensation of adamantane-1-carbaldehyde with 3-methoxypropionitrile, followed by reaction of resulting mixture of 2-adamantan-1-ylmethyl-3-methoxy-acrylonitrile and 3-adamantan-1-yl-2-methoxymethyl-acrylonitrile with guanidine, acetamidine and thiourea, respectively. The activity of c...

background: the measurement data regarding the influent and effluent of wastewater treatment plant (wwtp) provides a general overview, demonstrating an overall performance of wwtp. nevertheless, these data do not provide the suitable operational information for the optimization of individual units involved in a wwtp. a full-scale evolution of wwtp was carried out in this study via a reconciled ...

In January of 1979, a railroad tank car containing the chemical acrylonitrile started leaking at a rail yard in south suburban Chicago. The chemical was manufactured by American Cyanamid Co (Cyanamid) in Louisiana. Cyanamid had leased the tank car, filled it with acrylonitrile, and delivered it to the Missouri Pacific Railroad for transport to the Chicago suburbs. The leak occurred while the ca...

In the title compound, C(20)H(18)N(2)O(3), the C=C bond of the acrylonitrile group that links the indole and the 3,4,5-trimeth-oxy-phenyl rings has Z geometry, with dihedral angles between the plane of the acrylonitrile unit and the planes of the benzene and indole ring systems of 21.96 (5) and 38.94 (7)°, respectively. The acrylonitrile group is planar (r.m.s. deviation from planarity = 0.037 ...

Many new biomarkers are being studied, in addition to classical biomarkers, such as chemical substances and their metabolites in blood and urine and modified enzymes. Among these new biomarkers, hemoglobin adducts are thought to be especially useful for the estimation of chemical exposures. We review here the use of biomarkers for monitoring exposures to nine substances, mainly focusing on PRTR...

(Z)-3-(1H-Indol-3-yl)-2-(3-thienyl)acrylonitrile, C15H10N2S, (I), and (Z)-3-[1-(4-tert-butylbenzyl)-1H-indol-3-yl]-2-(3-thienyl)acrylonitrile, C26H24N2S, (II), were prepared by base-catalyzed reactions of the corresponding indole-3-carboxaldehyde with thiophene-3-acetonitrile. 1H/13C NMR spectral data and X-ray crystal structures of compounds (I) and (II) are presented. The olefinic bond connec...
