oléum : Nom commercial de l'acide sulfurique plus ou moins chargé d'anhydride SO3 [...]

CONT

On donne le nom d'oléum à tous les acides sulfuriques contenant plus d'anhydride SO3 que l'acide normal H2SO4, en raison de leur aspect huileux. [...] Ce sont des liquide épais, habituellement colorés en brun par les poussières organiques qui s'y trouvent carbonisées : ils laissent souvent déposer des cristaux d'acide pyrosulfurique H2S2O7. Les oléums servent principalement dans les réactions de sulfonation et de nitration (industries des matières colorantes, des explosifs, des plastiques, etc.).
