CAS 1333-82-0: Triossido di cromo
Descrizione:
Triossido di cromo, con il numero CAS 1333-82-0, è un composto chimico altamente tossico e corrosivo che appare come una polvere solida o cristallina di colore rosso scuro o nero. È principalmente noto per le sue forti proprietà ossidanti, rendendolo utile in varie applicazioni, tra cui la finitura dei metalli, l'elettrodeposizione e come reagente nella sintesi organica. Triossido di cromo è igroscopico, il che significa che assorbe facilmente l'umidità dall'aria, e può dissolversi in acqua per formare una soluzione altamente acida. Questo composto è classificato come cancerogeno e presenta rischi significativi per la salute, tra cui problemi respiratori e irritazione della pelle in caso di esposizione. A causa della sua natura pericolosa, Triossido di cromo è soggetto a rigorose normative riguardanti la sua manipolazione, stoccaggio e smaltimento. Oltre ai suoi usi industriali, svolge un ruolo nella produzione di sali di cromo e come catalizzatore in alcune reazioni chimiche. Misure di sicurezza adeguate, inclusi dispositivi di protezione individuale e ventilazione adeguata, sono essenziali quando si lavora con questa sostanza per mitigare i suoi effetti tossici.

CAS:It is widely used in chromium electroplating, and as protective coatings in corrosion/oxidation resistance of metals. It is also employed in CDs and DVDs. It is useful as an oxidant in Jones oxidation in acetic acid or acetone. It is used in the oxidation of primary alcohols into carboxylic acids, and secondary alcohols into ketones. With phosphoric acid, it is used as a stripping agent for anodic coatings of all types and in the production of syntheric rubies.
