Solventi non polari
I solventi non polari sono una classe di solventi che dissolvono composti non polari grazie alle loro basse costanti dielettriche e alla mancanza di cariche parziali significative. Sono ampiamente utilizzati in vari processi chimici e applicazioni, tra cui la sintesi organica, le estrazioni e la cromatografia. I solventi non polari comuni includono sostanze con anelli a 6 membri e Building Blocks come l'esano e il toluene, che sono cruciali per dissolvere composti idrofobici. Questi solventi svolgono un ruolo essenziale nella preparazione di ingredienti farmaceutici attivi (API) e composti di ricerca correlati. Inoltre, i solventi non polari sono utilizzati nella spettroscopia NMR, dove aiutano a dissolvere analiti non polari senza interferire con l'analisi spettrale. Sono anche importanti in processi che coinvolgono amminoacidi, composti organici clorurati e vari Building Blocks. La loro efficacia nel dissolvere composti organici rende i solventi non polari indispensabili sia in ambienti di laboratorio che industriali.
