A pilot scale plant at Technology Readiness Level (TRL) 6 comprising an electrochemical ex-cell continuous production of sodium peroxodicarbonate and a thermal depolymerization plug flow reactor for kraft lignin conversion is established. Due to the labile nature "green" oxidizer peroxodicarbonate, special attention must be paid parameters in order optimize its use. simplified design model describing steady-state transient operations formulated finally validated against experimental data from electrolysis setup. Design trade-offs are visualized, their impact on specific energy consumption evaluated. The was operated 20-month period more than 1200 h on-stream. Optimized process conditions result vanillin yields 8 wt % thus prove successful scale-up.

Abstract Synthetic electrochemistry may establish direct routes to a preparation of plethora organic substances, which are hardly accessible by conventional experimental techniques. Herein, we present an electrochemically‐driven method for assembly broad range rare heterocyclic mesoionic entities –1,2,3‐triazole 1‐imines. These nitrogen heterocycles were prepared through transition‐metal‐ and exogenous oxidant‐free strategy using C/Ni electrode pair. Over 30 examples thus synthesized 1,2,3‐triazole 1‐imines illustrate selectivity practical utility this approach. Key solvent‐controlled reactivity patterns the formation triazole imine scaffold revealed indicating modulation ability developed findings additionally justified based on cyclic voltammetry (CV) data density functional theory (DFT) calculations. Moreover, according differential scanning calorimetry (DSC) data, some correspond thermally stable species with onset decomposition temperature up 190 °C.
