    Microwave-assisted production of alkyl-polyglucoside from Sacha inchi oil and glucose
    (2023-07) Carvajal Ruiz, Uberney; Grisales Díaz, Victor Hugo; Caicedo, Carolina
    En este trabajo se han evaluado diferentes tiempos de reacción de microondas (0, 10, 20 y 30 min) para obtener un alquil poliglucósido de Sacha inchi (Plukenetia volubilis L.) y glucosa utilizando microondas a una potencia de 200 W y una temperatura de 70 °C. Las caracterizaciones de los respectivos resultados se realizaron por Espectroscopia Infrarroja Transformada de Fourier (FTIR) lo que permitió evidenciar el avance de la reacción. La cuantificación de glucosa residual se logró mediante el método colorimétrico de espectrometría mediante reacción con Antrona. El rendimiento de la reacción fue igual al 42.8%. Este estudio constituye un precedente importante para el desarrollo de tensoactivos en condiciones de reacción suaves.

    Sintesis y caracterización de alquilglucosido a partir de sacha inchi y glucosa asistido por microondas
    (Universidad Santiago de Cali, 2022-12-02) Carvajal Ruiz, Uberney; Grisales, Víctor Hugo; Caicedo Cano, Caicedo Cano
    A study on the production of an alkylglucoside type non-ionic surfactant is presented using microwaves at a power of 200 W with times of 10, 20 and 30 min and a temperature of 70 °C, the raw materials used for this reaction were sacha oil inchi and glucose, paratoluenesulfonic acid was used as catalyst. The characterizations of the respective products were carried out with fourier transform infrared spectroscopy (FTIR) and residual glucose quantification by means of the colorimetric method of spectrometry by reaction with Antrona. Positive results were obtained from the reaction, resulting in an amount of product equivalent to 24% by weight obtained.
