In the title complex, [RuCl(2)(C(8)H(12))(C(3)H(3)N)(2)], the metal ion is coordinated to centers of each of the double bonds of the cyclo-octa-1,5-diene ligand, to two chloride ions (in cis positions) and to two N-atom donors from two acrylonitrile mol-ecules that complete the coordination sphere for the neutral complex. The coordination about the Ru(II) atom can thus be considered octa-hedral...
A new versatile acrylonitrile-bioconverting strain isolated from a petroleum-contaminated sludge sample and identified as Rhodococcus ruber AKSH-84 was used for optimization of medium and biotransformation conditions for nitrilase activity to produce acrylic acid. A simple and rapid HPLC protocol was optimized for quantification of acrylic acid, acrylamide, and acrylonitrile. The optimal medium...
Acrylonitrile (ACN) is a petroleum-derived compound used in resins, polymers, acrylics, and carbon fiber. We present a process for renewable ACN production using 3-hydroxypropionic acid (3-HP), which can be produced microbially from sugars. The process achieves ACN molar yields exceeding 90% from ethyl 3-hydroxypropanoate (ethyl 3-HP) via dehydration and nitrilation with ammonia over an inexpen...

A novel aggregation- and crystallization-induced emission luminophore (ENPOMe) containing tetraphenylethene and acrylonitrile moieties with high fluorescence efficiency (Φ(F) of up to 0.85) has been easily synthesized. ENPOMe has an exceptionally large two-photon absorption cross section (σ) of 5548 GM, and exhibits striking multi-stimuli-responsive single- and two-photon fluorescence switching...
Soybean oils were packaged in polyvinylchloride, acrylonitrile, clear glass and amber glass bottles and their flavor stabilities were evaluated by a trained sensory panel. Hydrogenated and unhyrdogenated oils showed similar patterns of flavor deterioration regardless of container or type of aging. In accelerated light-exposure tests with air in the headspace, oils in plastic bottles showed flav...
In the title compound, C(13)H(10)Cl(2)N(2)O, the ring N atom and its three attached atoms are essentially coplanar with angles adding to 359.8°, indicating conjugation with the 2-formyl-acrylonitrile subunit. The aldehyde group is oriented to place the carbonyl O atom 2.02 (3) Å from the N-H hydrogen atom. Intra-molecular N-H⋯O and C-H⋯Cl inter-actions occur. The geometry of the exocyclic doubl...
