Abstract: A process is described herein for producing a low-volatile-matter organosilicon linear body. The process can include: removing chlorine ions from a dimethyl dichlorosilane hydrolysate, and reducing volatile matters at 180-280° C. and ?0.0955 to ?0.0998 MPa. The obtained organosilicon linear body can have volatile matters of less than 0.5%, a viscosity of 50-150 mm2/s and a content of chloride ions of lower than 1 ppm. The process can be widely applied to the production of organosilicon subsequent products such as low-ring-body-content 107 glue, low-ring-body-content amino silicone oil, low-ring-body-content methyl silicone oil, and low-ring-body-content vinyl silicone oil, and can meet requirements of the European Union on content limitations of ring bodies in a polymer.
