Silicone materials are a new type of chemical products with a wide variety, excellent performance and wide application. The synthesis of gas-solid fluidized monomer is one of the key technologies in the production of methylchlorosilane, which plays an important role in the industrialization of silicone. Methylchlorosilane is one of the most valuable and used silicone monomers, and it is the foundation and pillar of the whole silicone industry. Studying the bulk polymerization process of amino silicone oil is helpful to confirm the reaction mechanism and determine the structure of the product at each stage, and can also effectively control the reaction and make it proceed in the expected direction. Nuclear magnetic resonance (NMR) spectroscopy is a very powerful analytical technique, which is usually used to analyze the reaction mixture. Using NMR tracking technology to study the reaction process has the advantages of high speed, good repeatability and no termination of the reaction. In this paper, NMR is proposed to track the solution model reaction, and the structures of intermediate products and final products can be determined according to the corresponding NMR spectra, thus guiding the organic synthesis of the interface.
