Synthesis of terpineol is generally carried out by separation of α-pinene compounds from crude turpentine through fractionation and then hydrated (addition of water) with the help of acid catalysts. However, direct turpentine hydration without pre-fractionation process can be more beneficial from economic and process point of views. This study aims to investigate the effect of both single and mixed/combined catalysts towards terpineol yield. Combined strong and weak acid catalysts were required to obtain high feed conversion and terpineol yield. The selectivity of terpineol is then correlated to the solubility of a weak/organic acid. In this study, the highest yield of terpineol was 54.0 ± 8.2%-w/w using combination of formic acid and sulphuric acid.© 2020 The Author(s)Chemical engineering; Natural product chemistry; Catalyst; Chemical reaction engineering; Industrial chemistry; Chemical synthesis; Turpentine; Terpineol; Hydration reaction; Acid catalysts.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Acid catalysts,Catalyst,Chemical engineering,Chemical reaction engineering,Chemical synthesis,Hydration reaction,Industrial chemistry,Natural product chemistry,Terpineol,Turpentine[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][{‘$’: ‘This work was supported by the 2020 KIST School Partnership Project between the Korea Institute of Science and Technology (KIST) and the Institut Teknologi Bandung (ITB), and was partially funded by the Indonesian Ministry of Research Technology/National Agency for Research and Innovation, and the Indonesian Ministry of Education and Culture under the World Class University (WCU) Program managed by Institut Teknologi Bandung .
