In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 111-46-6, name is 2,2′-Oxybis(ethan-1-ol), the common compound, a new synthetic route is introduced below. name: 2,2′-Oxybis(ethan-1-ol)
To a solution of 2,2′-oxydiethanol (19.7 mL, 206.7 mmol, 3.0 eq.) in anhydrous THF (100 mL) was added sodium (0.1 g). The mixture was stirred until Na disappeared and then tert-butyl acrylate (10.0 mL, 68.9 mmol, 1.0 eq.) was added dropwise. The mixture was stirred overnight, and brine (200 mL) was added and extracted with EtOAc (3 × 100 mL). The organic layers were washed with brine (3 × 300 mL), dried over anhydrous Na2SO4, filtered, concentrated and purified by SiO2 column chromatography (1:1 hexanes/ EtOAc) to give to a colorless oil (8.10 g, 49.4% yield). MS ESI m/z calcd for C11H23O5 [M +H]+ 235.1467, found 235.1667.
The synthetic route of 111-46-6 has been constantly updated, and we look forward to future research findings.
