Dichloromethane (DCM) was a most reliable solvent for ROMP however for ROMP preformed in higher temperatures dichlorobenzene (DCBz) was found to be the best choice having a high boiling point and high dielectric constant ROMP preformed at higher temperatures up to 70 C gave better results in cases were low yields were obtained increasing the polymerization yields This was ascribed

However it usually is removed fairly easily from the manufacturing process using some high temperature vacuum since it has a much much lower boiling point than salicylic acid Furthermore unless some further purification is added to the process a small quantity (it can be as low as 0 05%) of 4-hydroxyisophthalic acid ( 4 ) is generated during the Kolbe-Schmitt reaction [1] (see again

Molecular engineering of G

Abstract Because various non-parallel G-quadruplexes of human telomeric sequences in K + solution can be converted to a parallel G-quadruplex by adding polyethylene glycol (PEG) as a co-solvent we have taken advantage of this property of PEG to study the covalent attachment of a PEG unit to a G-quadruplex ligand 3 6-bis(1-methyl-4-vinylpyridinium) carbazole diiodide (BMVC)

Pretreatment efficacy and lignin solubility of organic

For high-boiling point solvents the economic benefits of removing less water are remarkable (Chrisandina et al 2019) At 200 C and 2 h the pretreatment severity provided a wide delignification efficacy range and was more severe than standard kraft cooking Any greater severity would be impractical within an LVPP framework Another finding of note was the connection between a high
