In 2011,Guo, Zhenmei; Wang, Hengsheng; Lv, Zhiguo; Wang, Zhihui; Nie, Tao; Zhang, Weiwei published 《Catalytic performance of [Bmim][Co(CO)4] functional ionic liquids for preparation of 1,3-propanediol by coupling of hydroesterification-hydrogenation from ethylene oxide》.Journal of Organometallic Chemistry published the findings.Computed Properties of C4H8O3 The information in the text is summarized as follows:
In this paper, synthesis of 1,3-propanediol (1,3-PDO) through coupling of hydroesterification-hydrogenation from ethylene oxide (EO) catalyzed by 1-butyl-3-methylimidazolium cobalt tetracarbonyl [Bmim][Co(CO)4] functional ionic liquid which was prepared by metathesis reaction between [Bmim]Cl and KCo(CO)4 has been studied. The structure of [Bmim][Co(CO)4] was characterized by FT-IR and 1H NMR. Using [Bmim][Co(CO)4] as catalyst and [Bmim]PF6 as solvent, 1,3-PDO was prepared for the first time by coupling of hydroesterifaction of EO and hydrogenation of Me 3-hydroxypropionate (3-HPM). The yield of 3-HPM can reach 90.8%, while the yield of 1,3-PDO up to 82.9%. The catalyst can be separated from the product mixture by extraction with deionized water and recycled several times without significant loss of catalytic efficiency. A possible reaction mechanism has also been proposed. The results came from multiple reactions, including the reaction of Methyl 3-hydroxypropanoate(cas: 6149-41-3Computed Properties of C4H8O3)
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.
