Solvants non polaires
Les solvants non polaires sont une classe de solvants qui dissolvent les composés non polaires en raison de leurs faibles constantes diélectriques et de l'absence de charges partielles significatives. Ils sont largement utilisés dans divers processus chimiques et applications, y compris la synthèse organique, les extractions et la chromatographie. Les solvants non polaires courants incluent des substances avec des anneaux à 6 membres et des Building Blocks tels que l'hexane et le toluène, qui sont cruciaux pour dissoudre les composés hydrophobes. Ces solvants jouent un rôle essentiel dans la préparation d'ingrédients pharmaceutiques actifs (APIs) et de composés de recherche connexes. De plus, les solvants non polaires sont utilisés en spectroscopie RMN, où ils aident à dissoudre les analytes non polaires sans interférer avec l'analyse spectrale. Ils sont également importants dans les processus impliquant des acides aminés, des composés organiques chlorés et divers Building Blocks. Leur efficacité à dissoudre les composés organiques rend les solvants non polaires indispensables dans les environnements de laboratoire et industriels.
