In 2010,Lv, Zhiguo; Wang, Hengsheng; Li, Juan; Guo, Zhenmei published 《Hydroesterification of ethylene oxide catalyzed by 1-butyl-3-methylimidazolium cobalt tetracarbonyl ionic liquid》.Research on Chemical Intermediates published the findings.Recommanded Product: 6149-41-3 The information in the text is summarized as follows:
In this paper, functional ionic liquid 1-butyl-3-methylimidazolium cobalt tetracarbonyl [Bmim][Co(CO)4] is prepared in a metathesis reaction between [Bmim]Cl and KCo(CO)4. The structure of [Bmim]+ is illustrated by 1H NMR, while [Co(CO)4]- is confirmed by IR(νCO) spectrum. Me 3-hydroxypropionate(3-HPM), an intermediate to 1,3-propanediol (1,3-PDO), can be prepared in high yield by hydroesterification of ethylene oxide in the presence of a [Bmim][Co(CO)4] catalyst. Under a pressure of 3.7 MPa and at 75°, the yield of 3-HPM can reach 90.8% in 10 h. Even after the catalyst is recycled three times, a yield of more than 80% can be obtained. A possible reaction mechanism has also been proposed. In the experiment, the researchers used many compounds, for example, Methyl 3-hydroxypropanoate(cas: 6149-41-3Recommanded Product: 6149-41-3)
Methyl 3-hydroxypropanoate(cas: 6149-41-3) belongs to esters with low molecular weight are commonly used as fragrances and found in essential oils and pheromones. 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.
