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:

Investigation of Extraction of 4-Oxopentanoic Acid by N,N-Dioctyloctan-1-amine in Six Different Diluents: Equilibrium Study
TL;DR: In this paper, the effect of acid concentration and type of diluent on the recovery of 4-oxopentanoic acid from aqueous solution was investigated. But the results were limited to 1:1 and 2:1 complexes between acid and TOA.

TL;DR: In this article, the microwave-assisted hydrolysis of bamboo (Phyllostachys nigra “Boryana”) to 5-hydroxymethylfurfural (HMF) and furfural in a dilute acid/methyl isobutyl ketone (MIBK) biphasic system is investigated.

One-pot catalytic conversion of Nordic pulp media into green platform chemicals
TL;DR: In this article, both sulphite and sulphate (Kraft) cellulose from Nordic pulp mills were used as raw materials in the catalytic one-pot synthesis of green platform chemicals, levulinic and formic ac...

TL;DR: It has been found that levulinic acid has a high capacity to dissolve kraft lignin at room temperature, and its efficiency is not compromised when diluting the acid with water (up to 40 wt% water content), and the Kamlet-Taft π⁎ parameter was estimated and found to correlate well with their solubility performance.

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.
