| titleOfInvention | Industrial method for preparing and purifying 4, 4' -dimethoxy triphenylchloromethane |
| abstract | The invention discloses an industrial method for preparing and purifying 4, 4' -dimethoxytriphenylchloromethane, which takes anisole and trichlorotoluene as initial raw materials to prepare a DMT-Cl crude product through an F-C reaction, a hydrochloric acid hydrolysis reaction and a chlorination reaction, wherein the purity of the DMT-Cl crude product is more than 98.5 percent, the DMT-Cl crude product is crystallized by a solvent to obtain a DMT-CL finished product with the purity of more than 99.9 percent, and the yield of the DMT-CL finished product is more than 80 percent. The industrial method for preparing and purifying the 4, 4' -dimethoxy triphenylchloromethane has reasonable design, can avoid using a format reagent and a more expensive refined solvent, achieves the aim of producing the DMT-CL with high purity in a safe, environment-friendly and industrialized way, and meets the high-quality standard of biological nucleoside and nucleotide. |
