Aqueous methyldiethanolamine (MDEA) is used as a solvent in natural gas sweetening unit, whose quality deteriorates while absorbing H2S/CO2 causing corrosion and foaming in the process. Total process contaminants of lean MDEA obtained from GASCO Company (Habshan, Abu Dhabi) were determined using different instruments. The major hydrocarbons found in inlet natural gas was analyzed using gas chromatography mass spectrometry (GC-MS). Heat stable salt (HSS) anions and metal ions were detected using ion chromatograph (IC) and inductively coupled plasma optical emission spectrometry (ICP-OES). Liquid chromatography mass spectrometry (LC-MS) and direct sample analysis time of flight (AxION 2TOF) analysis were carried out to determine and major organic degraded products present in lean MDEA solvent. The UV-VIS spectrophotometer also justified the presence of total organic acid anions. Acetate and propionate were found to be present in higher amounts of 2806 and 1614 ppm, respectively. Substantial amount of metal ions were also detected using ICP-OES with maximum level of heavy metal ions of lead and iron of 1.009 and 0.967 ppm, respectively. Large numbers of organic degraded products such as diethanolamine followed by methylethanolamine, N,N-bis(2-hydroxyethyl) glycine (bicine) etc. were identified using LC-MS and AxION 2TOF analyses; which are considered to be major organic thermally degraded products. Thermal degradation experiment was compared with H2S and in presence of both H2S/CO2 to obtain same compounds with varying concentration. On the basis of MDEA degradation as reported by previous researchers and from the analyzed lean MDEA samples, probable reaction pathways have been proposed.

A new practical method for the N-acylation of amides is described. Acylation of various amides with acid anhydrides in the presence of MgBr2·OEt2 gave the corresponding N-acylamides in good to moderate yields. The present method is applicable to amides that are labile to acids or bases.

The pyrimidine nucleus is a versatile core in the development of antiretroviral agents. Onthis basis, a series of pyrimidine-2,4-diones linked to an isoxazolidine nucleus have been synthesized and tested as nucleoside analogs, endowed with potential anti-HIV (human immunodeficiency virus) activity. Compounds 6a-c, characterized by the presence of an ethereal group at C-3, show HIV reverse transcriptase (RT) inhibitor activity in the nanomolar range as well as HIV-infection inhibitor activity in the low micromolar with no toxicity. In the same context, compound 7b shows only a negligible inhibition of RT HIV.

Application of 497-25-6, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 497-25-6, Name is Oxazolidin-2-one,introducing its new discovery.

N-Acyl oxazolidinones of simple carboxylic acids and amino acids were observed to undergo successful SmI2-promoted couplings with substituted acrylamides and acrylates, affording a variety of functionalized gamma-ketoamides and -esters with yields attaining 85%. As many of these reductive couplings were previously found to be ineffective employing the corresponding 4-pyridylthio esters, the applicability of this methodology has been substantially improved. The methodology has been adapted to prepare structures related to two potent aspartate protease inhibitors, the renin inhibitor aliskiren, and the gamma-secretase inhibitor L-685,458. Finally, a convenient two-step procedure for the preparation of N-acyl oxazolidinones of N-protected amino acids, which provides consistently good yields of the corresponding imide, has been devised.

According to Deslongchamps’ theory of stereoelectronic control, preferentioal cleavage of a tetrahedral intermediate occurs when there are two lone pairs antiperiplanar to the leaving group.For reasons presented (Perrin and Arrhenius, J.Am.Chem.Soc. 1982, 104, 2839), product studies of hydrolysis of cyclic amidines can test this theory, and initial results supported it.However, those results are ambiguous, owing to a mismatch of leaving abilities.We now find that hydrolysis of three six-membered ring amidines bearing matched leaving groups produces predominantly aminoamide, the product of ring cleavage, and only 3-9percent lactam, as expected from the theory.In contrast, hydrolysis of three five- or seven-membered ring amidines produces substantial (ca. 50percent) lactam.Despite attempts to accomodate these results to the theory, it is concluded that there is no general requirement for two lone pairs antiperiplanar to the leaving group and that stereoelectronic control, even in six-membered ring amidines, contributes less than 2 kcal/mol.
