Role of aqueous methyldiethanolamine (MDEA) as solvent in natural gas sweetening unit and process contaminants with probable reaction pathway

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.

On the structure of the Phytophthora alpha1 mating hormone: synthesis and comparison of four candidate stereoisomers

Two two-compound mixtures of candidate structures for the Phytophthora alpha1 mating hormone have been synthesized. The mixtures were designed to have differing configurations at C3, but proved to be identical. This suggests that epimerization occurred at C3, and comparison with the data for the natural samples suggest that this is also a mixture of isomers.

Targeted repositioning identifies drugs that increase fibroblast growth factor 20 production and protect against 6-hydroxydopamine-induced nigral cell loss in rats

Endogenous fibroblast growth factor 20 (FGF20) supports maintenance of dopaminergic neurones within the nigrostriatal pathway. Moreover, direct intracerebral infusion of FGF20 protects against nigrostriatal tract loss in the 6-hydroxydopamine lesion rat model of Parkinson?s disease. Increasing endogenous FGF20 production might provide a less-invasive, more translational way of providing such protection. Accordingly, we adopted a targeted repositioning approach to screen for candidate FDA-approved drugs with potential to enhance endogenous FGF20 production in brain. In silico interrogation of the Broad Institute?s Connectivity Map database (CMap), revealed 50 candidate drugs predicted to increase FGF20 transcription, 16 of which had profiles favourable for use in Parkinson?s disease. Of these, 11 drugs were found to significantly elevate FGF20 protein production in MCF-7 cells, between two- and four-fold. Four drugs were selected for examination in vivo. Following oral dosing in rats for 7 days, salbutamol and triflusal, but not dimethadione or trazodone, significantly elevated FGF20 levels in the nigrostriatal tract. Preliminary examination in the unilateral 6-hydroxydopamine-lesioned rat revealed a modest but significant protection against nigral cell loss with both drugs. Our data demonstrate the power of targeted repositioning as a method to identify existing drugs that may combat disease progression in Parkinson?s by boosting FGF20 levels.

Efficient and recyclable Cu2(BDC)2(BPY)-catalyzed oxidative amidation of terminal alkynes: Role of bipyridine ligand

We have described an efficient method for oxidative cross coupling reactions between activated N-H amines and terminal alkynes using heterogeneous Cu2(BDC)2(BPY) as recyclable catalyst (BDC = benzene-1,4-dicarboxylate; BPY = 4,4?-bipyridine). The optimal conditions involved the use of inexpensive NaHCO3 base and oxygen as terminal oxidant in toluene solvent at 80C. Reactions proceeds efficiently, and high selectivity with only trace amount of diynes as well as good yields were achieved in a short reaction time. The Cu2(BDC)2(BPY) exhibited excellent catalytic activity and selectivity as compared to other Cu-MOFs on a broad reaction scope. Interestingly, the presence of bipyridine ligand was shown to enhance the catalyst stability. Thus, the Cu2(BDC)2(BPY) could be facilely separated from the reaction mixture by simple centrifugation and could be reused several times with only a slight decrease in catalytic activity.

Thermal degradation comparison of amino acid salts, alkanolamines and diamines in CO2 capture

In the selection of candidates for post-combustion CO2 absorption, solvent degradation has become a general concern due to the significant impact on operational cost and the intention to use thermal compression from high temperature stripping to minimize the overall process energy. In this research, structural analogs of amino acid salts, alkanolamines and diamines were thermally degraded in order to explore their thermal stability from a structural standpoint. Functional groups, amine orders and steric effect were investigated for their impact on amine thermal degradation. Primary amines with chain structures showed a thermal stability trend as diamine > alkanolamine > amino acid salt. For alknolamine and diamine structural isomers, the primary amines are more stable than the secondary amines. Steric hindrance around the amine group was shown to play a positive role in protecting amines against thermal degradation.

Applications of the chiral auxiliaries DIOZ and TRIOZ for conjugate additions and comparison with other auxiliaries

A number of N-acryloyl-, N-crotonoyl-, N-(3,3,3-trifluorocrotonoyl)-, N-cinnamoyl-, and N-(3-nitroacryloyl)-4-isopropyl- or -4-phenyl-oxazolidin-2- ones with geminal diphenyl substitution, i.e., 7-15, have been prepared and used for conjugate additions of organocuprate reagents (Me, iPr, Ph, 4-MeOPh) in the beta-carbonyl (Table 2) and in the alpha-carbonyl position (NO2-derivative 11 in Scheme 3). The yields and diastereoselectivities are compared with previously tested enoyl-oxazolidinones (Table 2). Highest diastereoselectivities (>90%) are always observed with the 4-Ph derivatives (Hruby effect). Nitroacryloyl-oxazolidinones and a corresponding phenylmenthol ester undergo less diastereoselective additions (Scheme 3). A 3-(1-methylethyl)-5,5-diphenyloxazolidin-2-one (DIOZ)-derived Li2-enolatenitronate was also tested for alpha-carbonyl alkylation (Scheme 4). The X-ray crystal structures of three acryloyl-oxazolidinones and of four adducts are described (Tables 1 and 3), and they serve for configurational assignments and description of the stereochemical courses of the additions and alkylation. Possible applications of the nitro compounds for the preparation of beta2-amino acids are discussed (Scheme 2).

Substituted cis-hydrindan-4-ones by sequential cycloadditions

The synthesis of substituted cis-hydrindan-4-ones is reported. Particular emphasis was placed on the diastereoselective construction of quaternary stereogenic ring carbon atoms. An intermolecular asymmetric Al(III)-promoted (4+2)-cycloaddition served as the principal C/C-connecting tool. Opportunities for the further structural elaboration of the (4+2)-cycloadducts were explored.
