Fine Chemicals from Lignosulfonates. 1. Synthesis of Vanillin by Oxidation of Lignosulfonates
TLDR
In this article, a multivariate mathematical and statistical design and modelling has been used for the process optimisation has led to the development of a multiivariate mathematical model which describes the oxidation process with high predictive capacity, an increase of the vanillin yield from 4.1% of the current procedure to 7.2% is obtained.About:

Lignin depolymerization (LDP) in alcohol over nickel-based catalysts via a fragmentation–hydrogenolysis process
Qi Song,Qi Song,Feng Wang,Jiaying Cai,Jiaying Cai,Yehong Wang,Junjie Zhang,Junjie Zhang,Weiqiang Yu,Jie Xu +9 more
TL;DR: In this article, the authors showed that lignin can be selectively cleaved into propylguaiacol and propylsyringol with total selectivity >90% at a lignins conversion of about 50%.

Vanillin Production from Lignin and Its Use as a Renewable Chemical
TL;DR: The use of vanillin as a building block for the chemical industry is discussed in this article, where vanillin is one of the only molecular phenolic compounds manufactured on an industrial scale from biomass and has the potential to become a key intermediate for the synthesis of bio-based polymers, for which aromatic monomers are needed to reach good thermo-mechanical properties.

Use of Half-Normal Plots in Interpreting Factorial Two-Level Experiments
TL;DR: In this article, the empirical cumulative distribution of the usual set of orthogonal contrasts computed from a 2 p experiment on a special grid may be used to estimate the error standard deviation and to make judgments about the reality of the observed effects.
