US Patent 11498046 Method and system for tetrachloromethane synthesis

Methods and systems are provided for photochemically synthesizing tetrachloromethane in an industrial scale using a plurality of arrays or channels of light emitting diodes. A wavelength output by an SLM lamp is customized to bias the photochemical reaction towards a target reaction and target product and away from a side reaction and side product. The higher yield of the target product improved efficiency and reduces the need for complex purification for removal of the side product.
