The burgeoning interest in new electrochemical methods holds promise to provide a plethora of strategic disconnections for pharmaceutical compounds that are safer, less wasteful, and more streamlined than traditional chemical strategies. use organic electrochemistry the commercial production pharmaceuticals is exceedingly rare due lack modular infrastructure. Herein we describe cascading continuous stirred tank reactors with individual cell potential control applied over reaction "stages" which demonstrate balance between high selectivity throughput necessary be viable strategy space. Using degree afforded by this reactor design, 1 kg demonstration was achieved 9 h yield (2.6 kg/day throughput).

Electrochemically generated green platform oxidizers like peroxodicarbonate (PODIC) constitute a game-changing technology in terms of sustainable chemistry while serving as an alternative counterreaction the electrochemical hydrogen evolution. Peroxodicarbonate avoids storage and shipping concentrated peroxide solution. We herein disclose efficient method for N-oxidation quinolines, pyridines, complex tertiary amines. The use phenoyloxy succinimide (POSI) is decisive factor obtaining N-oxides (28 examples) isolated yields up to 98%.

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.

Lampung is the third largest producer of nutmeg (Myristica fragrans) in Sumatra Island, Indonesia. Most essential oil refining industries process seeds, but not many distill leaves. Therefore, it necessary to identify chemical compounds determine potential for further processing products and quality oil. The leaf samples were obtained from a industry Pesawaran, Lampung, oils identified using gas chromatography-mass spectrometry. Nutmeg was then evaluated according SNI 06-2388-2006 as standard testing data analyzed descriptively. results 28 active Compounds with high relative abundance streptamine (76.46%), aquinolizine (4.67%), boron (3.73%), kaurene (2.03%), pyrrole (1.95%), naphthalene.
