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.). 6, record 1, French, - ol%C3%A9um
