Catalytic Conversion of Dihydroxyacetone to Lactic Acid Using Metal Salts in Water
Rasrendra, Carolus B.; Fachri, Boy Arief; Makertihartha, I. Gusti B. N.; Adisasmito, Sanggono; Heeres, Hero J. (2016-08-31)We herein present a study on the application of homogeneous catalysts in the form of metal salts on the conversion of trioses, such as dihydroxyacetone (DHA), and glyceraldehyde (GLY) to lactic acid (LA) in water. A ... -
Experimental and modeling studies on the acid-catalyzed conversion of inulin to 5-hydroxymethylfurfural in water
Fachri, Boy Arief; Abdilla; Rasrendra, Carolus Borromeus; Heeres, Hero J. (2016-08-31)Inulin is considered as an attractive feed for the synthesis of 5-hydroxymethylfurfural (HMF), an important biobased platform chemical with high application potential. We here report a systematic study to optimize the ... -
Experimental and Modeling Studies on the Conversion of Inulin to 5-Hydroxymethylfurfural Using Metal Salts in Water
Fachri, Boy Arief; Rasrendra, Carolus Borromeus; Heeres, Hero J. (2016-08-31)Inulin, a plant polysaccharide consisting of mainly D-fructose units, is considered an interesting feed for 5-hydroxymethylfurfural (HMF), a top 12 bio-based chemical. We here report an exploratory experimental study on ... -
Experimental and modelling studies on the uncatalysed thermal conversion of inulin to 5-hydroxymethylfurfural and levulinic acid
Fachri, Boy Arief; Abdilla; Rasrendra; Heeres (2016-08-31)Background: 5-Hydroxymethylfurfural (HMF), an important biobased platform chemical, is accessible by the acid catalysed conversion of biopolymers containing hexoses (cellulose, starch, inulin) and monomeric sugars ... -
Experimental Study and Modeling on Supercritical CO2 Extraction of Indonesian Raw Propolis using Response Surface Method: Influence of Pressure, Temperature and CO2 Mass Flowrate on Extraction Yield
Fachri, Boy Arief; Sari, Puspita; Yuwanti, Sih; Subroto, Erna (Chemical Engineering Research and Design 153 ( 2020 ) 452–462, 2020-01-01)It is well-known that propolis shows potential as an antioxidant. A common method to extract propolis is organic solvent extraction which has drawbacks such as long extraction times and solvent residues. To overcome this, ... -
Flame Characteristics of Diffusion of Calophyllum inophyllum Methyl Ester on Mini Glass Tube
Bachtiar, Hemas Hafidh; Fachri, Boy Arief; Ilminnafik, Nasrul (2019-07-04)Combustion is a chain chemical reaction that is influenced by three factors, namely fuel, oxidizer, and heat. This study analyzes the effect variations of fuel flow rates (1 ml/h, 2 ml/h, and 3 ml/h) on the laminar burning ... -
