Colloids and Surfaces, A: Physicochemical and Engineering Aspects published new progress about 1589-47-5. 1589-47-5 belongs to ethers-buliding-blocks, auxiliary class Aliphatic hydrocarbon chain,Alcohol,Ether, name is 2-Methoxypropan-1-ol, and the molecular formula is C4H10O2, Name: 2-Methoxypropan-1-ol.

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.

Mortazavi, Saeideh-Sadat’s team published research in Applied Organometallic Chemistry in 34 | CAS: 1589-47-5

Applied Organometallic Chemistry published new progress about 1589-47-5. 1589-47-5 belongs to ethers-buliding-blocks, auxiliary class Aliphatic hydrocarbon chain,Alcohol,Ether, name is 2-Methoxypropan-1-ol, and the molecular formula is C4H10O2, Quality Control of 1589-47-5.

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.

4-(Benzyloxy)-3-methylphenol (cas: 100927-02-4) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

2-Methoxyethylamine (cas: 109-85-3) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Safety of 2-Methoxyethylamine

5-Methoxy-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzaldehyde (cas: 1132669-90-9) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Electric Literature of C14H19BO4

Reinisch, Jens et al. published their research in Industrial & Engineering Chemistry Research in 2016 | CAS: 112-59-4

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.SDS of cas: 112-59-4
