Aplicaciones de las fragancias

Las fragancias son compuestos orgánicos volátiles derivados de aceites naturales, como los aceites de cítricos, mediante el uso de resinas adsorbentes, o bien compuestos sintéticos producidos a través de rutas de catálisis o biocatálisis. Mientras que la mayoría de las esencias y fragancias se purifican por vía de destilación debido a su alta volatilidad, algunas requieren purificación por resinas cuando la volatilidad de la fragancia es próxima a la de sus impurezas. Cuando la destilación no proporciona la selectividad que necesita, los distintos productos químicos de resinas de intercambio iónico de Purolite le serán de ayuda.

Mientras que algunas fragancias y esencias son parte de la fórmula de perfumes y colonias, otras se agregan a detergentes de limpieza y aromatizantes de ambiente, como el linalool, que tiene aroma a pino y se puede purificar de su impureza más próxima, el gerol, por vía de adsorción. El linalool también se puede extraer del cilantro mediante el uso de la adsorción Purolite.

Moreover, the law sets limits for each pesticide, but sometimes in products from conventional agriculture, the total concentration of pesticides exceeds limits for commercial acceptance creating health and commercial problems. In the end, it is extremely difficult to manufacture citrus oils free from pesticides, even if fruits are grown in organic mode.

Specific ion-exchange resins manufactured by Purolite are able to eliminate or, at least, substantially reduce up to 90% pesticide content in citrus essential oils.

The system is based on an adsorption and ion exchange process in a column; citrus oils are percolated through cartridges loaded with specific ion exchangers. Through this system, it is possible to obtain an oil with greatly reduced pesticide content and with no significant change of other characteristics. Purolite can provide further information about operating conditions and expected results.

The resin system has been validated with very good results both with lemon oil and orange oil. Among common pollutants, just chlorpyrifos content remains unchanged, but considering that this pesticide has been recently banned in the European Union, it is a problem that will likely be resolved over time.
