Synthesis of Furfural from Water Hyacinth(Eichornia croassipes)

Autor: R S Purbowatiningrum, Haq, FH Rafi’ah, Tri Windarti, Ngadiwiyana, Suyanti, M Hapsari, Ismiyarto

Publikováno v: IOP Conference Series: Materials Science and Engineering. 172:012027

Furfural has been prepared from hydrolysis of dried biomass of water hyacinth (Eichornia crassipes) by using diluted hydrochloric acid and sulphuric acid as catalysts. This process involved the conversion of the pentosane fraction in water hyacinth i
