Paragraph 0015-0017, (2020/05/30)
The invention discloses a synthesis process of indoxacarb. The method comprises the following steps: reacting m-chlorobenzaldehyde serving as a raw material with malonic acid to remove monomolecular water and carbon dioxide to generate an intermediate SRCA, performing a hydrogenation reduction on the intermediate SRCA in an autoclave in the presence of a catalyst to obtain an intermediate SRCH, and cyclizing the SRCH by using hydrogen fluoride as a dehydrating agent to obtain the final product indoxacarb. The synthesis process is simple and easy to implement, energy is saved, consumption is reduced, the yield is increased, and good economic and environmental benefits are obtained.

Paragraph 0022; 0023, (2017/06/02)
The invention discloses a method for separation purification of an indoxacarb S-isomer from an indoxacarb mixture by solvent recrystallization. An organic solvent used by the method is an acetonitrile, alcohol, hydrocarbon, ether or ester solvent or their mixture having any ratio. A temperature of recrystallization is in a range of -10 to 10 DEG C. The indoxacarb S-isomer finished product has indoxacarb S-isomer purity greater than 98% and satisfies market demands of the indoxacarb S-isomer.
