Influenza della temperatura di pirolisi e del tempo di residenza sulle proprietà fisico-chimiche del biochar prodotto da pollina

2013

La pollina è tradizionalmente utilizzata in agricoltura come fertilizzante organico grazie al suo alto contenuto in nutrienti immediatamente disponibili per le piante (principalmente azoto, potassio e fosforo). Nonostante i vantaggi apportati alle colture, l’eccessivo uso della pollina come ammendante del suolo può causare gravi problemi ambientali, tra cui rischi per la salute umana e lisciviazione di nitrati o altri inquinanti nelle acquee sotterranee. Per diminuire i rischi legati al suo utilizzo, una soluzione alternativa potrebbe essere il ri-utilizzo energetico della pollina tramite la sua conversione in biochar. Il biochar è una sostanza carboniosa derivante dalla pirolisi di qualsia…

Clerodane diterpenoids from Salvia splendens.

2006

Four new clerodane diterpenoids, salvisplendins A-D (1-4), have been isolated from an acetone extract of the flowers of SalVia splendens, together with an artifact (5), arising from salvisplendin D (4) by addition of diazomethane, and the already known clerodane olearin (6). The structures of the new compounds (1-5) were established mainly by 1D and 2D NMR spectroscopic studies and, in the case of salvisplendin A (1), by chemical correlation with splenolide B (7). Complete 1H and 13C NMR assignments for olearin (6), not published hitherto, are also reported.
