Adhiputra, Randy; Utami, Maisari; Suyono, Eko Agus; Budiman, Arief; Hariani, Poedji Loekitowati; Pratiwi, Ani Setyo; Wijaya, Karna published the artcile< Simultaneous extraction and in-situ transesterification of Chlorella vulgaris using microwave-assisted method for biodiesel production>, SDS of cas: 112-63-0, the main research area is extraction Chlorella microwave biodiesel.
This research aims to study the simultaneous extraction and transesterification of Chlorella vulgaris (C. vulgaris) using microwave irradiation with methanol as solvent and potassium hydroxide (KOH) as catalyst. The microwave-assisted insitu transesterification of C. vulgaris is assessed at various ratios of biomass-to-methanol, reaction times, and catalyst concentrations during the centrifugation and evaporation process. Gas chromatog.-mass spectrometry (GC-MS) anal. is performed to confirm fatty acid Me ester (FAME) composition Biodiesel preparation is carried out by simultaneous extraction and transesterification of microalgae from C. vulgaris. The product is then characterized using Fourier transform IR spectroscopy (FTIR) and proton NMR (1H-NMR); microalgae are observed using SEM (SEM). The highest amount of FAME is obtained at a biomass-to-methanol ratio of 1:12, reaction time of 40 min, and catalyst concentration of 2 wt%. Biodiesel shows conversion to about 77.64% of Me ester (Me myristate, Me palmitoleate, Me linoleate, Me oleate, Me arachidonate, and Me 5,8,11,14,17-eicosapentanoate).
