Zhang, Jiawei published the artcileNano metal oxides as efficient catalysts for selective synthesis of 1-methoxy-2-propanol from methanol and propylene oxide, COA of Formula: C4H10O2, the publication is RSC Advances (2018), 8(8), 4478-4482, database is CAplus.

Nano metal oxides such as Fe₂O₃, Fe₃O₄, CuO, NiO, ZnO and SnO₂ were prepared and characterized using XRD, SEM and TEM anal. These as-prepared metal oxide materials were used as catalysts for the etherification of methanol with propylene oxide (PO). The results showed that α-Fe₂O₃ exhibited outstanding catalytic performance with 97.7% conversion and 83.0% selectivity to MP-2 at 160 °C for 8 h. Furthermore, the relationship between the catalytic activity or selectivity and surface basicity or energy gap was investigated. This catalyst could be easily recovered and reused due to its heterogeneous catalytic nature.

De, Chunyan published the artcileHighly selective synthesis of propylene glycol ether from methanol and propylene oxide catalyzed by basic ionic liquid, Related Products of ethers-buliding-blocks, the publication is Journal of Chemical Technology and Biotechnology (2011), 86(1), 105-108, database is CAplus.

Propylene glycol ether is expected to be a safe substitute for toxic ethylene glycol ether usually used in industry owing to its negligible toxicity. Although catalysis of solid acids or bases for the synthesis of the ether can avoid separation of catalysts, liquid waste treatment and corrosion problems, it suffers from drawbacks, e.g. lower activity and selectivity to target product, high reaction pressure and temperature In order to solve these problems, a basic ionic liquid, namely choline hydroxide was prepared and used as a catalyst for synthesis of the ether via atom-economy reaction from propylene oxide and methanol. The ionic liquid showed excellent catalytic performance exhibiting 95.4% conversion of propylene oxide (PO) and 94.6% selectivity to 1-methoxy-2-propanol. It is also an effective catalyst for the reaction of PO with other primary alcs. to yield corresponding ethers. In addition this catalyst can be recovered and reused. The high activity and selectivity can probably be ascribed to its basicity and/or the strong polarity and electrostatic field of the reaction medium caused by the ionic liquid

A series of basic and acidic ionic liquids, 1-butyl-3-methylimidazolium hydroxide (BMIMOH), 1-acetyl-3-methylimidazolium chloride (AcMIMCl) and AcMIMCl-FeCl₃, or analogs of AcMIMCl, namely 1-potassium acetate-3-methylimidazolium chloride (KAcMIMCl), 1-potassium (sodium, ammonium) acetate-3-methylimidazolium hydroxides (KAcMIMOH, NaAcMIMOH and NH₄AcMIMOH), were prepared and used as catalysts for catalytic synthesis of propylene glycol ether via reaction of propylene oxide (PO) with methanol under mild reaction conditions. KAcMIMOH exhibited outstanding catalytic performance with 94.2% of conversion of PO and 99.1% of selectivity to 1-methoxy-2-propanol (MP-2) at 60°C and ambient pressure for 4 h. However, AcMIMCl-FeCl₃ showed a good catalysis performance with high selectivity to 2-methoxy-1-propanol (MP-1). The tunable synthesis of MP-2 or MP-1 catalyzed by basic compound KAcMIMOH or acidic ionic liquid AcMIMCl-FeCl₃ was realized.

Elamin, Khalid published the artcileGlass transition and relaxation dynamics of propylene glycol-water solutions confined in clay, Related Products of ethers-buliding-blocks, the publication is Journal of Chemical Physics (2014), 141(3), 034505/1-034505/8, database is CAplus and MEDLINE.

The mol. dynamics of aqueous solutions of propylene glycol (PG) and propylene glycol methylether (PGME) confined in a two-dimensional layer-structured Na-vermiculite clay has been studied by broadband dielec. spectroscopy and differential scanning calorimetry. As typical for liquids in confined geometries the intensity of the cooperative α-relaxation becomes considerably more suppressed than the more local β-like relaxation processes. In fact, at high water contents the calorimetric glass transition and related structural α-relaxation cannot even be observed, due to the confinement. Thus, the intensity of the viscosity related α-relaxation is dramatically reduced, but its time scale as well as the related glass transition temperature T_g are for both systems only weakly influenced by the confinement. In the case of the PGME-water solutions it is an important finding since in the corresponding bulk system a pronounced non-monotonic concentration dependence of the glass transition related dynamics has been observed due to the growth of hydrogen bonded relaxing entities of water bridging between PGME mols. [J. Sjostrom, J. Mattsson, R. Bergman, and J. Swenson, Phys. Chem. B 115, 10013 (2011)]. The present results suggest that the same type of structural entities are formed in the quasi-two-dimensional space between the clay platelets. It is also observed that the main water relaxation cannot be distinguished from the β-relaxation of PG or PGME in the concentration range up to intermediate water contents. This suggests that these two processes are coupled and that the water mols. affect the time scale of the β-relaxation. However, this is most likely true also for the corresponding bulk solutions, which exhibit similar time scales of this combined relaxation process below T_g. Finally, it is found that at higher water contents the water relaxation does not merge with, or follow, the α-relaxation above T_g, but instead crosses the α-relaxation, indicating that the two relaxation processes are independent of each other. This can only occur if the two processes do not occur in the same parts of the confined solutions Most likely the hydration shell of the interlayer Na⁺ ions is causing this water relaxation, which does not participate in the α-relaxation at any temperature (c) 2014 American Institute of Physics.

Mortazavi, Saeideh-Sadat published the artcileA new Bronsted acid MIL-101(Cr) catalyst by tandem post-functionalization; synthesis and its catalytic application, Quality Control of 1589-47-5, the publication is Applied Organometallic Chemistry (2020), 34(8), e5717, database is CAplus.

A new heterogeneous Bronsted solid acid catalyst was prepared by tandem post-functionalization of MIL-101(Cr) and utilized for acetic acid esterification and alcoholysis of epoxides under solvent-free conditions. First, MIL-101(Cr) was functionalized with pyrazine to achieve MIL-101(Cr)-Pyz. Afterwards, the nucleophilic reaction of MIL-101(Cr)-Pyz with 1,3-propane sultone and next acidification with diluted sulfuric acid gave MIL-101(Cr)-Pyz-RSO₃H Bronsted solid acid catalyst. Various characterization methods such as Fourier transformation IR (FT-IR) spectroscopy, X-ray diffraction (XRD), elemental anal. (CHNS), XPS, SEM (SEM), energy-dispersive X-ray (EDX) spectroscopy, thermal anal. (TGA/DTA), acid-base titration, and N₂ adsorption/desorption anal. were employed to fully characterize the prepared catalyst. The catalyst showed high activity compared to unmodified MIL-101(Cr) in both catalytic acetic acid esterification and alcoholysis of epoxides. It can also be readily isolated from the reaction mixture and reused three times without major decrease in its activity.

Mortazavi, Saeideh-Sadat published the artcileInfluence of -SO₃H groups incorporated as Bronsted acidic parts by tandem post-synthetic functionalization on the catalytic behavior of MIL-101(Cr) MOF for methanolysis of styrene oxide, Name: 2-Methoxypropan-1-ol, the publication is Colloids and Surfaces, A: Physicochemical and Engineering Aspects (2020), 124703, database is CAplus.

Two kinds of Bronsted solid acid catalyst based on MIL-101(Cr) support were prepared by tandem post-synthetic functionalization. Covalent attachment of piperazine and DABCO (DABCO = 1,4 diazabicyclo[2.2.2]octane) followed by reaction with 1,3-propane sultone led to achieving MIL-pip-SO₃H and MIL-DABCO-SO₃H, resp. The obtained catalysts were characterized using several techniques which confirmed the presence of SO₃H groups in the MIL-101(Cr) framework. The catalytic behavior of the functionalized MIL-101(Cr) were evaluated and compared in the methanolysis of styrene oxide. Both solid acid catalysts showed superior catalytic efficiency compared to pristine MIL-101(Cr) under identical reaction conditions due to the presence of SO₃H groups, indicating the effect of post-synthetic modification on MIL-101(Cr) MOF.
