Synthesis of bio-derived 1,4-butanediol by succinic acid esterification and hydrogenation over CuFeAl catalysts

Abstract

Sustainability concern has led to the gradual expansion of the bio-derived 1,4-butanediol (BDO) monomer market, for the replacement of traditional plastics with biodegradable plastics. Herein, we reported a new environmentally...

Identifying the Active Site and Structure–Activity Relationship in Hydrodeoxygenation of Ester to Alcohols over an Al2O3@CuZn Core–Shell Catalyst

“…The activity of the Cu-based catalysts decreased due to the migration of Cu atoms. Li et al reported a Cu 1 Fe 1 Al 0.5 catalyst and confirmed that the strong interaction of Cu and Al could prevent Cu from aggregating during recycling. Cao et al prepared a Mo–Ni@Al 2 O 3 catalyst and demonstrated a high dispersion of metals on the surface of the core–shell catalyst.…”

A perspective on catalytic production of olefinic compounds from biomass

“…Each butanediol isomer (1,2-, 1,3-, 1,4-and 2,3-) can be obtained with an appropriate bacterial species. Chemical synthesis of butanediols from biomass-derived compounds is possible, such as hydrogenation of succinic acid [149][150][151][152] and hydrogenolysis of erythritol 6,124,153,154 and 1,4-anhydroerythritol. [155][156][157] The chemically synthesized butanediol is usually the 1,4-isomer, although some methods produce a mixture of isomers.…”
