Annotation
In this work, a study was conducted on the synthesis of high molecular weight organosilicon oligomers such as oligoethylsiloxane based on 1,2-dichloroethane and sodium metasilicate. The synthesis was carried out via a three-step nucleophilic displacement and condensation reaction in the presence of ethylene glycol, in a dimethylsulfoxide (DMSO) solvent, and in an autoclave using potassium hydroxide as a catalyst. The structure of the resulting oligomer was confirmed by FTIR analysis, and its thermal stability was determined by TGA/DTA. The resulting oligomer has hydrophobic properties and can be used in the separation of oil-water mixtures and in the biomedical field.
