In 2019,Chinese Chemical Letters included an article by Ali, Mohammad Chand; Liu, Ruirui; Chen, Jia; Cai, Tianpei; Zhang, Haijuan; Li, Zhan; Zhai, Honglin; Qiu, Hongdeng. Application In Synthesis of 1,4,7,10,13-Pentaoxacyclopentadecane. The article was titled 《New deep eutectic solvents composed of crown ether, hydroxide and polyethylene glycol for extraction of non-basic N-compounds》. The information in the text is summarized as follows:
Here we firstly report a series of new deep eutectic solvents (DESs) induced by small amounts of crown ether complex and mainly formed by polyethylene glycol. These DESs not only presented the ultra-deep extraction of non-basic N-compounds from fuel oils, but also opened up the possibility of other new applications in chem. and materials science. The experimental part of the paper was very detailed, including the reaction process of 1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5Application In Synthesis of 1,4,7,10,13-Pentaoxacyclopentadecane)
1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5) is a member of crown ether Ligands. Crown-ethers are macrocyclic polyethers capable of forming host-guest complexes, especially with inorganic and organic cations. Crown-ethers can incorporate protonated primary amine compounds by formation of ion-dipole bonds with the oxygen atoms of the chiral selector. Crown-ethers have been widely used for the separation of several pharmaceuticals both in aqueous and non-aqueous media. Application In Synthesis of 1,4,7,10,13-Pentaoxacyclopentadecane
