Abstract：
Renewable chemicals, which are made from renewable resources such as biomass, have attracted significant interest as substitutes for natural gas- or petroleum-derived chemicals to enhance the sustainability of the chemical and petrochemical industries. Polybutylene adipate terephthalate (PBAT), which is a copolyester of 1,4-butanediol (1,4-BDO), adipic acid (AA), and dimethyl terephthalate (DMT) or terephthalic acid (TPA), has garnered significant interest as a biodegradable polymer. This study assesses the non-biological production of PBAT monomers from biomass feedstocks via heterogeneous catalytic reactions. The biomass-based catalytic routes to each monomer are analyzed and compared to conventional routes. Although no fully commercialized catalytic processes for direct conversion of biomass into 1,4-BDO, AA, DMT, and TPA are available, emerging and promising catalytic routes have been proposed. The proposed biomass-based catalytic pathways toward 1,4-BDO, AA, DMT, and TPA are not yet fully competitive with conventional fossil fuel-based pathways mainly due to high feedstock prices and the existence of other alternatives. However, given continuous technological advances in the renewable production of PBAT monomers, bio-based PBAT should be economically viable in the near future.
摘要：
可再生化学品,由生物质等可再生资源制成，作为天然气或石油衍生化学品的替代品，以增强化学和石化行业的可持续性，引起了人们的极大兴趣。聚己二酸对苯二甲酸丁二醇酯(PBAT),它是1,4-丁二醇（1,4-BDO）的共聚酯，己二酸(AA),和对苯二甲酸二甲酯（DMT）或对苯二甲酸（TPA），作为可生物降解的聚合物已经引起了极大的兴趣。这项研究评估了通过非均相催化反应从生物质原料中非生物生产PBAT单体。分析每种单体的基于生物质的催化途径并与常规途径进行比较。虽然没有完全商业化的催化工艺将生物质直接转化为1,4-BDO，AA,DMT,和TPA是可用的，新兴和有希望的催化路线已被提出。提出的基于生物质的催化途径对1,4-BDO，AA,DMT,和TPA尚未与传统的基于化石燃料的途径完全竞争，主要是由于高原料价格和其他替代品的存在。然而,鉴于PBAT单体可再生生产的持续技术进步，生物基PBAT在不久的将来应该在经济上可行。
