La recuperación mejorada de petróleo (EOR) en yacimientos no convencionales requiere el desarrollo de tensoactivos con alta estabilidad térmica y química en condiciones extremas. En este trabajo se reporta la síntesis de un novedoso tensoactivo tipo Gemini a base de polidimetilsiloxano (PDMS) con un rendimiento del 60%. La síntesis se realizó en un solo paso sin catalizador metálico, ofreciendo una ruta simplificada frente a métodos convencionales, a partir de PDMS con grupos terminales diglicidil éter (PDMS-DGE) y 1-octanol. La estructura fue confirmada mediante Resonancia Magnética Nuclear de protón (1H-RMN) y espectroscopia infrarroja (FT-IR). Las propiedades superficiales, evaluadas por el método de ángulo de contacto sésil, determinaron una Concentración Micelar Crítica (CMC) de 0.88 mM. Este valor indica una alta eficiencia o rendimiento en la formación de micelas y en la reducción de la tensión interfacial utilizando bajas concentraciones del tensoactivo.
