Figure 6From: Catalysis over zinc-incorporated berlinite (ZnAlPO4) of the methoxycarbonylation of 1,6-hexanediamine with dimethyl carbonate to form dimethylhexane-1,6-dicarbamateEffect of the ZnAlPO 4 /HDA ratio (mg/mmol) on HDA conversion, yield of dicarbamate and selectivity for reaction products. Reaction conditions: HDA, 200 mmol; DMC/HDA, 8; time, 8 h; temperature, 353 K. (Legend: (□) HDA conversion; (○) yield of dicarbamate; (■), (●) and (▲), selectivity for dicarbamate, monocarbamate and N-methylated-carbamate, respectively.)Back to article page
