Síntesis de nopol a partir de trementina: revisión del estado del arte

Abstract: MSC: 92.E20 ResumenEn esta contribución se hace una revisión de los métodos para la síntesis del nopol. Los procesos convencionales abarcan la síntesis térmica y la catalíti-ca con ZnCl2 y los emergentes corresponden a los catalíticos heterogéneos. Se destaca el uso de catalizadores de Sn soportado en materiales mesoporosos producto de las investigaciones de la última década en el Grupo Catálisis Ambiental. La evaluación de las tecnologías existentes de producción de nopol muestra ventajas de la síntesis térmi… Show more

“…Using a more efficient catalyst such as Sn-MCM-41 for the transformation of β-pinene, is possible to reduce the temperature of the process below 100 C with the additional advantage of ease separation and reuse of the catalyst. Over Sn-MCM-41, yields between 90 and 100% have been reported [12,13,14,15], values that exceed the optimum yield reported (71%) with the homogeneous catalyst ZnCl 2 [4]. The mesoporous properties (large surface area with pores diameters between 1.5 to 10 nm [16] and a thin pore-walls of 1-1.5 nm [17]) of the MCM-41 allow the diffusion of the β-pinene molecule into the large pore sizes that facilitate they reach the active tin species.…”

“…PF is typically used as HCHO source when anhydrous reaction conditions are mandatory; for instance, for obtaining homoallylic alcohols from the Prins condensation of alkenes and HCHO [4]. This reaction has been widely studied to obtain nopol from b-pinene and PF over tin catalyst supported on mesoporous materials [5]. According to Table 1, nopol yield could be strongly affected by the specific properties of PF, in contrast to PF commercialized in powder, the nopol yield using PF commercialized in prills was lower and significantly affected by particle size.…”
