It targets limitations of conventional homogeneous acid processes, which face catalyst inactivation in high-FFA waste cooking oil and generate large amounts of acidic wastewater during purification. Building on the benefits of sulfonic acid sites and the porous, tunable structure of MOFs, the work aims to enhance catalytic performance and reusability while improving process sustainability. Key preparation factors include sulfuric acid concentration, sulfonation time, and sulfonation temperature.","cbCaimDxeiAkSkMV","https://ap.wps.com/l/cbCaimDxeiAkSkMV","pdf",965698,1,1778619635,{"code":4,"msg":22,"data":23},"ok",{"site_id":24,"language":25,"slug":26,"title":13,"keywords":27,"description":14,"schema_data":28,"social_meta":62,"head_meta":64,"extra_data":66,"updated_unix":20},105,"en","dilute-sulfonic-acid-post-functionalized-metal-organic-framework-as-a-heterogeneous-acid-catalyst-for-esterification-to-produce-biodiesel","",{"@graph":29,"@context":61},[30,47],{"@type":31,"itemListElement":32},"BreadcrumbList",[33,37,41,44],{"item":34,"name":35,"@type":36,"position":19},"https://docshare.wps.com","Home","ListItem",{"item":38,"name":39,"@type":36,"position":40},"https://docshare.wps.com/document/","Document",2,{"item":42,"name":12,"@type":36,"position":43},"https://docshare.wps.com/document/research-report/",3,{"item":45,"name":13,"@type":36,"position":46},"https://docshare.wps.com/document/dilute-sulfonic-acid-post-functionalized-metal-organic-framework-as-a-heterogeneous-acid-catalyst-for-esterification-to-produce-biodiesel/31084",4,{"url":45,"name":13,"@type":48,"author":49,"headline":13,"publisher":51,"fileFormat":54,"description":14,"dateModified":55,"datePublished":55,"encodingFormat":54,"isAccessibleForFree":56,"interactionStatistic":57},"DigitalDocument",{"name":9,"@type":50},"Person",{"url":34,"name":52,"@type":53},"DocShare","Organization","application/pdf","2026-05-12",true,{"@type":58,"interactionType":59,"userInteractionCount":4},"InteractionCounter",{"@type":60},"ViewAction","https://schema.org",{"og:url":45,"og:type":63,"og:title":13,"og:site_name":52,"og:description":14},"article",{"robots":65,"canonical":45},"index,follow",{"doc_id":7,"site_id":24}]
