“…The production of 1,4-butanediol from furan was possible with a bimetallic Ru-Re/C catalyst (Ru: 1 wt%; Re: 5 wt%) at 160 o C under 3 MPa H 2 , resulting in a 68% yield of 1,4-butanediol [70]. The 1,4-butanediol derived from furfural via succinic acid or furan intermediates must be further dehydrated to obtain butadiene [71][72][73]. Wang et al recently reported a 96.6% yield of butadiene by using a rare earth oxide catalyst such as ytterbium(III) oxide (Yb 2 O 3 ) at 360 o C and a WHSV of 0.44 h 1 [72].…”

Renewable biomass-derived chemicals have received considerable interest as a potential substitute for petroleum-derived chemicals. Hexamethylenediamine is a key intermediate in manufacturing nylon 66, a synthetic polymer that is broadly used in society. This article reviews the catalytic production of hexamethylenediamine from biomass-derived chemical feedstocks, and specifically the bio-based routes for obtaining hexamethylenediamine. While methods to directly convert biomass to hexamethylenediamine have yet to be commercialized, the use of heterogeneous catalytic systems via combined processes appears to be a promising and emerging chemical pathway to achieve this goal. Current proposed routes for the renewable production of hexamethylenediamine are not yet entirely competitive with petrochemical production techniques, predominantly because of low efficiency and high cost. However, many opportunities exist to advance technologies that exploit renewable and bio-based feedstocks to generate hexamethylenediamine. Thus, the commercialization of biomass-derived nylon monomers appears achievable in the near future.

“…Therefore, Wang et al [65] studied the production of BD by the dehydration of 3B1OL and 1,4-butanediol over rare earth oxides, such as Lu 2 O 3 and Yb 2 O 3 . The optimal result of the dehydration of 3B1OL was obtained with a high conversion of 99.6% and a good BD selectivity of 96.7% over the Yb 2 O 3 catalyst at 340 • C. Accordingly, the direct dehydration of 1,4-BDO to BD over Yb 2 O 3 also exhibited excellent a catalytic performance with a yield of 96.6% at 360 • C. Thus, producing BD from bio-derived C4 alcohols and especially unsaturated C4 alcohols via the dehydration process is a promising route, although a large amount of work still needs to be done, especially for improving catalyst life for industry usage.…”

“…Thus, it is concluded that the dehydration mechanism of 3B1OL to BD is quite different from the dehydration of 2B1OL and 3B2OL. Therefore, Wang et al [65] studied the production of BD by the dehydration of 3B1OL and 1,4-butanediol over rare earth oxides, such as Lu2O3 and Yb2O3. The optimal result of the dehydration of 3B1OL was obtained with a high conversion of 99.6% and a good BD selectivity of 96.7% over the Yb2O3 catalyst at 340 °C.…”

Synthetic rubbers fabricated from 1,3-butadiene (BD) and its substituted monomers have been extensively used in tires, toughened plastics, and many other products owing to the easy polymerization/copolymerization of these monomers and the high stability of the resulting material in manufacturing operations and large-scale productions. The need for synthetic rubbers with increased environmental friendliness or endurance in harsh environments has motivated remarkable progress in the synthesis of BD and its substituted monomers in recent years. We review these developments with an emphasis on the reactive routes, the products, and the synthetic strategies with a scaling potential. We present reagents that are primarily from bio-derivatives, including ethanol, C4 alcohols, unsaturated alcohols, and tetrahydrofuran; the major products of BD and isoprene; and the by-products, activities, and selectivity of the reaction. Different catalyst systems are also compared. Further, substituted monomers with rigid, polar, or sterically repulsive groups, the purpose of which is to enhance thermal, mechanical, and interface properties, are also exhaustively reviewed. The synthetic strategies using BD and its substituted monomers have great potential to satisfy the increasing demand for better-performing synthetic rubbers at the laboratory scale; the laboratory-scale results are promising, but a big gap still exists between current progress and large scalability.

Elastomers play an irreplaceable role in our society due to their unique properties. Natural rubber is directly obtained from plants and is widely used in tires, shoes, etc. Recently, modified natural rubbers are proposed to expand the application of natural rubber. However, these natural rubbers have a limited variety of molecular structures and may not be able to meet ever-demanding applications. Traditional synthetic elastomers have a variety of molecular structures and their properties are used in various fields, but mainly originate from fossil resources. This review deals with bio-based elastomers, and more specifically natural rubber and bio-based synthetic elastomers. Based on reprocessability, bio-based elastomers can also be divided into bio-based chemically cross-linked ones and thermoplastic ones. Compared to traditional fossil-based elastomers, bio-based ones may alleviate environmental pollution and promote the sustainable development of the elastomer industry.
