Levulinic acid production from wheat straw.
TLDR
The coefficient determination (R(2)) was good for the second-order model and the optimal conditions for levulinic acid production from wheat straw were 209.3 degrees C, 3.5% acid concentration, 15.6 liquid:solid ratio and 37.6 min of reaction time resulted 19.86% yield.About:

Integrated two-stage chemically processing of rice straw cellulose to butyl levulinate.
TL;DR: Effectiveness of co-solvent treatment on rice straw for potential fermentable sugar release (glucose) was investigated by subjecting the respective post-reaction solid residues to enzymatic digestion using cellulase and yielded highest of 11% wt.

Optimisation studies on the conversion of oil palm biomass to levulinic acid and ethyl levulinate via indium trichloride-ionic liquids: A response surface methodology approach
TL;DR: In this paper, a response surface methodology based on a central composite design method was used to optimise the operating conditions of the conversions of oil palm empty fruit bunch and mesocarp fiber biomass to levulinic acid and ethyl levulinate via an eco-friendly indium trichloride-1-methylimidazolium hydrogen sulfate.
Journal ArticleDOI
Ball milling pretreatment and diluted acid hydrolysis of oil palm empty fruit bunch (EFB) fibres for the production of levulinic acid
TL;DR: In this paper, a wide angle X-ray diffraction analysis, particle-size distribution and scanning electron microscopy were performed on the pre-treated EFB fibres and the results showed that the effectiveness of the pretreatment was correlated with the yield of acid hydrolysis to produce levulinic acid (LA).
Journal ArticleDOI
Catalytic production of levulinic acid and ethyl levulinate from uniconazole-induced duckweed (Lemna minor).
TL;DR: This work provides a promising strategy for the production of value-added chemicals from phytoplankton that is able to purify the wastewater containing high content of P and N.
Journal ArticleDOI
Extractive separation of levulinic acid using natural and chemical solvents
TL;DR: In this paper, Levulinic acid separation from aqueous streams, different types of solvents (sunflower and groundnut oil), and various chemical solvent (benzene, iso-butanol, and iso-octanol) at 298.15 K were used.

A response surface approach for the comparison of lipase production by Candida cylindracea using two different carbon sources
TL;DR: Medium containing olive oil appears to a better medium for fermentative production of C. cylindracea lipase than yeast extract, malt extract, peptone and tween 80, based on experimental conditions.

Mechanism of levulinic acid formation
TL;DR: Based on the intermediates revealed by 13C-NMR spectroscopy, the mechanism of levulinic acid formation in acid catalysed hydrolysis of 2-hydroxymethylfurane (1) and 5-hexyl carbaldehyde (2-carbaldehyde) is proposed in this paper.

Experimental studies for levulinic acid production from whole kernel grain sorghum
Qi Fang,Milford A. Hanna +1 more
TL;DR: This study proposed a method of making levulinic acid using abundant and low cost whole kernel sorghum grain as the raw material and a linear regression model was capable of predicting the levulini acid yield with respect to effects of reaction temperature, mineral acid concentration and flour loading.
