Novel route for the synthesis of methyl propionate from 3 - pentanone with dimethyl carbonate over solid bases / Zhi Chen in Industrial & engineering chemistry research, Vol. 50 N° 22 (Novembre 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 22 (Novembre 2011) . - pp. 12343-12348 Titre : Novel route for the synthesis of methyl propionate from 3 - pentanone with dimethyl carbonate over solid bases Type de document : texte imprimé Auteurs : Zhi Chen, Auteur ; Dudu Wu, Auteur Année de publication : 2012 Article en page(s) : pp. 12343-12348 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Methyl  Dimethyl  Carbonate Résumé : A novel and simple route for the synthesis of methyl propionate by the methoxycarbonylation of 3-pentanone with dimethyl carbonate in the presence of solid base catalysts was developed. Solid bases with moderate strength (such as MgO) facilitated the formation of methyl propionate, and the yield of methyl propionate could be linearly correlated with the amount of moderate basic sites. The function of basic catalysts was mainly attributed to the activation of 3-pentanone through the abstraction of the α-H by base sites.

Synthesis of dimethyl pimelate from cyclohexanone and dimethyl carbonate over solid base catalysts / Dudu Wu in Industrial & engineering chemistry research, Vol. 48 N° 13 (Juillet 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 13 (Juillet 2009) . - pp. 6287–6290 Titre : Synthesis of dimethyl pimelate from cyclohexanone and dimethyl carbonate over solid base catalysts Type de document : texte imprimé Auteurs : Dudu Wu, Auteur ; Zhi Chen, Auteur Année de publication : 2009 Article en page(s) : pp. 6287–6290 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Dimethyl  pimelate  Carbomethoxycyclohexanone  Solid  base  catalysts Résumé : The synthesis of dimethyl pimelate (DMP) was carried out from cyclohexanone and dimethyl carbonate in the presence of solid base catalysts. The results showed that the intermediate carbomethoxycyclohexanone (CMCH) was produced from cyclohexanone with DMC in the first step, and then CMCH further converted to DMP by reacting with methoxide group. The function of basic catalysts was mainly attributed to the activation of cyclohexanone via the abstraction of proton in the α position by base sites, and solid base with moderate strength, such as MgO, facilitated the formation of DMP.
