A novel process was developed for the production of bio-based 1,5-pentanediol (1,5-PDO) from 3,4-dihydro-2H-pyran (DHP) and acetic acid (AA) in this work. The esterification of DHP and AA achieved a 59.8% DHP conversion and 91.2% tetrahydropyran-2-yl acetate selectivity (THPOAc) at 373 K for 1 h and DHP/AA molar ratio of 1 without catalyst. Then the 1,5-PDO with selectivity of 54.5% was obtained from THPOAc via hydrogenation over Cu/Zn/Al catalyst under the conditions of 453 K and 50 bar. The higher dispersion of Cu nanoparticles, the larger surface area of metallic Cu, the higher amount of Cu active sites and the lower acidity of Cu/Zn/Al catalyst were beneficial for the hydrogenation of THPOAc to 1,5-PDO.","PeriodicalId":12794,"journal":{"name":"Green Synthesis and Catalysis","volume":"143 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139980030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
