Opis ogólny

In the solid-phase synthesis of oligonucleotides, liquid reagents are used in each step of the synthesis cycle. Overall synthesis performance, and therefore total product yield and purity of the crude oligonucleotide, is highly dependent on the chemical purity of the monomers and the supporting liquid reagents and other solvents like ethylacetate, dichloromethane, and dimethylformadine .Ethyl acetate (EA), a carboxylate ester, is a bio-friendly organic solvent with a wide range of industrial applications. Ethyl acetate can be obtained via an esterification reaction between ethyl alcohol and acetic acid in the presence of sulfuric acid. Its synthesis by reactive distillation and by acceptorless dehydrogenative dimerization of ethanol has been explored. Its ability as an acyl acceptor in the immobilized lipase-mediated preparation of biodiesel from crude vegetable oils has been examined. The complete degradation of ethyl acetate to CO2 using manganese octahedral molecular sieve (OMS-2) has been investigated. EA is an effective alternate solvent of diethyl ether, employed for the concentration of eggs, larvae, and cysts in fecal specimens during the Formalin-ether sedimentation technique.

Zastosowanie

Ethyl acetate may be used in the following studies:
  • As a solvent for the isolation of Rose hip (Rosa canina L., Rosaceae) powder, via sonication.
  • As a solvent for the abstraction of volatile thiols from wine for their quantitative estimation by gas chromatography/mass spectrometry (GC-MS).
  • Preparation of thin films of TiO2 (titanium dioxide) on glass.
  • As an extraction medium in the multi-residue analysis of pesticide residues in fruit and vegetables.
  • Acetylaton of primary amines to form amides in the presence of dimethyltin(IV) acetic acid distannoxane.

Strigolactone changes and cross talk with ABA unveil a picture of root-specific hormonal dynamics under stress. Strigolactones (SLs) are carotenoid-derived hormones influencing diverse aspects of development and communication with (micro)organisms, and proposed as mediators of environmental stimuli in resource allocation

Plant-derived volatile compounds such as terpenes exhibit substantial structural variation and serve multiple ecological functions. Despite their structural diversity, volatile terpenes are generally produced from a small number of core 5- to 20-carbon intermediates. Here, we present unexpected plasticity in

Escherichia coli produces the iron-chelating compound enterobactin to enable growth under iron-limiting conditions. After biosynthesis, enterobactin is released from the cell. However, the enterobactin export system is not fully understood. Previous studies have suggested that the outer membrane channel TolC

Bacterial cholesterol oxidase is commonly used as an experimental tool to reduce cellular cholesterol content. That the treatment also generates the poorly degradable metabolite 4-cholesten-3-one (cholestenone) has received less attention. Here, we investigated the membrane partitioning of cholestenone using simulations

The aim of the present experiment was to compare silage prepared from maize having a brown midrib (BMR) mutation with control (CTR) maize to identify their effects on enteric methane emission, digesta mean retention time (MRT), ruminal fermentation and digestibility.
