Abstract: This invention presents an electrochemical metallurgical technique for extracting metals and sulfur from metal sulfides, offering an adjustable composition and mechanical properties during electrode preparation. The metal sulfide anode, submerged in an electrolyte with a cathode made of materials like titanium, copper, stainless steel, lead, zinc, aluminum or graphite, undergoes electrolysis. This process oxidizes sulfur in the metal sulfide to the anode and releases metal ions into the electrolyte, where they're reduced at the cathode. The method yields metal at the cathode and sulfur at the anode, with minimal environmental impact, low investment, and straightforward process.

Abstract: A field of asymmetric catalytic synthesis, and in particular a preparation method for a high optical indoxacarb intermediate includes reacting 5-chloro-2-methoxycarbonyl-1-indanone ester (or indanone ester for short) with an oxidizing agent in the presence of a chiral Zr-salen polymer to obtain an indoxacarb intermediate (2S)-5-chloro-2,3-dihydro-2-hydroxy-1-oxo-1H-indole-2-carboxylic acid methyl ester. The yield is stabilized between 86% and 90%, and the S-enantiomer content is up to 99%. Such catalyst can replace catalysts such as cinchonine, and greatly increase the content of the effective S-enantiomer of the indoxacarb, so that the content of the hydroxyl intermediate S-enantiomer of the indoxacarb is raised from 75% to 99% or more. In addition, the chiral Zr-salen polymer catalyst is recycled without retreatment, and can be recycled at least 5 times or more, greatly reducing the production cost and laying a foundation for the industrial production of high quality indoxacarb.

The catalyst is prepared using 3-tert-butyl-5-(chloromethyl)salicylaldehyde and cyclohexanediamine as raw materials, where an original quinine catalyst such as cinchonine is replaced with the catalyst for application in the asymmetric synthesis of tert-butyl hydroperoxide and 5-chloro-2-methoxycarbonyl-1-indanone ester, greatly improving selection in the asymmetric synthesis process, with the S-enantiomer content increasing from 75% to over 98%, achieving the recycling of a high-efficiency chiral catalyst, and greatly reducing production costs. The synthesis process of the catalyst is simple and is favorable for industrialization, and lays good foundations for the production of high-quality indoxacarb.
