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:

Conversion of wheat straw into formic acid in NaVO3–H2SO4 aqueous solution with molecular oxygen
TL;DR: In this paper, the production of FA from wheat straw, an abundant lignocellulosic biomass, in NaVO3-H2SO4 aqueous solution with molecular oxygen (O2) was studied.

Kinetic Studies on Wheat Straw Hydrolysis to Levulinic Acid
TL;DR: In this paper, the kinetics of levulinic acid accumulation in the hydrolysis process of wheat straw was investigated using dilute sulfuric acid as a catalyst, and the kinetic experiments were performed in a temperature range of 190-230°C and an acid concentration range of 1%-5% (by mass).

A new functionalized ionic liquid for efficient glucose conversion to 5-hydroxymethyl furfural and levulinic acid
TL;DR: In this article, three types of functionalized ionic liquids (FILs) were used as catalysts in the conversion of glucose to 5-hydroxymethyl furfural (5-HMF) and levulinic acid (LA) using ionic liquid is a promising method for producing liquid fuels from renewable resources.
Journal ArticleDOI
Behaviors of glucose decomposition during acid-catalyzed hydrothermal hydrolysis of pretreated Gelidium amansii
TL;DR: From the results, H(2)SO(4) was the most suitable catalyst for glucose production, but glucose decomposition occurred during the hydrolysis, which resulted in a low glucan yield and formic acid and levulinic acid.
Journal ArticleDOI
Optimization of Biomass Conversion to Levulinic Acid in Acidic Ionic Liquid and Upgrading of Levulinic Acid to Ethyl Levulinate
TL;DR: In this paper, the optimization of LA production from glucose and oil palm fronds (OPF) catalyzed by an acidic ionic liquid; 1-sulfonic acid-3-methyl imidazolium tetrachloroferrate ([SMIM][FeCl4]) have been investigated.

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.
