Abstract: The present invention relates to a production method for a liquid high-purity organosilicon compound, the method comprising the steps of: adding, to a mixture containing an organosilicon compound selected from a group consisting of organomodified silcones and organomodified silanes and impurities, an organic wax having affinity with the impurities and having a higher melting point than the organosilicon compound, melting and mixing while heating, and introducing the impurities into the melted organic wax; obtaining a solidified product of the organic wax by cooling the organic wax; and performing solid/liquid phase separation on the organosilicon compound and the solidified product of the organic wax. With the present invention, it is possible to provide a useful method for producing a high-purity organosilicon compound stably and on a commercial scale.

Abstract: The present invention relates to a monoalkenyl-containing glycerin derivative with purity of not less than 92% and electrical conductivity of not greater than 50 μS/cm. The monoalkenyl-containing glycerin derivative can be manufactured by a manufacturing method comprising a step (A): a step of reacting a ketalized glycerin derivative and a monoalkenyl glycidyl ether in the presence of an inorganic base to obtain a ketal of monoalkenyl-containing glycerin derivative; a step (B): a step of purifying the ketal of monoalkenyl-containing glycerin derivative obtained in the step (A) by distillation; and a step (C): a step of hydrolyzing the ketal of monoalkenyl-containing glycerin derivative obtained in the step (B). The present invention is able to provide a high-purity monoalkenyl-containing glycerin derivative that was difficult in the past. It is further able to provide a glycerin derivative-modified silicone, and applications therefor, that is chemically stable, and further has excellent utility for its emulsifiability, and the like, and excellent formulation stability.

Abstract: A production method for a liquid high purity sugar derivative-modified silicone or a composition thereof is disclosed. The method comprises the steps of: 1) capturing hydrophilic impurities in solid particles by causing an impurity containing composition containing liquid sugar derivative-modified silicone and the hydrophilic impurities derived from a sugar derivative to contact the solid particles, the sugar derivative being a hydrophilic modifier of the sugar derivative-modified silicone, and the solid particles being able to capture the hydrophilic impurities; and 2) separating the sugar derivative-modified silicone and the solid particles. The method is useful for production of the liquid high purity sugar derivative-modified silicone and the composition thereof on a commercial scale.
