| description | Procedure for the manufacture of a yellow-orange varnish and product obtained. The present invention relates to a process for the manufacture of a yellow-orange varnish characterized in that it comprises the following phases: (I) a mixture consisting of acetaldehyde and an aqueous solution of sodium sulphite is stirred for at least 75 minutes at 10º c, obtaining the aldol, (II) the aldol obtained in phase (I) is stirred for at least 12 hours, at room temperature obtaining the polyaldol (III) the polyaldol obtained in step (II) is dissolved in ether and washed, in a separating funnel, with water. The resulting organic extract is dried at least 30 minutes over anhydrous sodium sulfate and, subsequently, it is filtered and concentrated in a rotary evaporator, obtaining a colored oil, (IV) the colored oil obtained in step (III) is dissolved in acetone and also diluted with acetone, obtaining an orange yellow varnish. The proposed procedure allows to obtain a varnish with yellow-orange coloration without the use of dyes. (Machine-translation by Google Translate, not legally binding)
Procedimiento para la fabricación de un barniz amarillo-naranja y producto obtenido. La presente invención se refiere a un procedimiento para la fabricación de un barniz amarillo-naranja caracterizado porque comprende las siguientes fases: (i) Se procede a la agitación de una mezcla consistente en acetaldehído y una solución acuosa de sulfito sódico durante al menos 75 minutos, a 10°C, obteniendo el aldol, (ii) Se procede a la agitación del aldol obtenido en la fase (i) durante al menos 12 horas, a temperatura ambiente obteniendo el polialdol (iii) El polialdol obtenido en la fase (ii) se disuelve en éter y se lava, en embudo de decantación, con agua. El extracto orgánico resultante se deseca al menos 30 minutos sobre sulfato sódico anhidro y, posteriormente, se filtra y concentra en rotavapor, obteniéndose un aceite coloreado, (iv) El aceite coloreado obtenido en la fase (iii) se disuelve en acetona y diluye también con acetona, obteniéndose un barniz amarillo naranja. El procedimiento propuesto permite obtener un barniz con coloración amarillo-naranja sin necesidad de emplear colorantes. |
