CAS 6153-56-6: Acide éthanedioïque hydraté (1:2)
Description :
Acide éthanedioïque hydraté (1:2), également connu sous le nom d'acide oxalique dihydraté, est un composé chimique avec la formule C2H2O4·2H2O. C'est un solide cristallin incolore qui est hautement soluble dans l'eau, formant une solution claire. Ce composé se caractérise par ses propriétés acides, car c'est un acide dicarboxylique, ce qui signifie qu'il contient deux groupes fonctionnels carboxyles (-COOH). La présence de molécules d'eau dans sa structure contribue à sa stabilité et à sa solubilité. L'acide éthandioïque hydraté est couramment utilisé dans diverses applications, notamment comme agent réducteur dans les réactions chimiques, dans l'industrie textile pour le blanchiment et dans la préparation de certains oxalates métalliques. Il est important de manipuler cette substance avec précaution, car elle peut être toxique et irritante pour la peau et les yeux. De plus, elle peut former des complexes avec des ions métalliques, ce qui est significatif en chimie analytique et dans les études environnementales. Des conditions de stockage appropriées sont nécessaires pour maintenir sa stabilité et prévenir la dégradation.

Oxalic acid dihydrate
CAS :Oxalic acid dihydrate is an organic compound with the molecular formula of (C2H2O4)2. It has a molecular weight of 226.07 g/mol and a melting point of 173°C. The intermolecular hydrogen bonding between the hydroxyl groups and the fatty acid chains creates an oxalic acid molecule that is able to exist in two different structures, alpha and beta. Alpha oxalic acid molecules have a particle phase transition temperature of -10°C, while beta oxalic acid molecules have a particle phase transition temperature of 30°C. Oxalic acid dihydrate is soluble in n-dimethylformamide (DMF) and hydrochloric acid (HCl). br>br> Oxalic acid dihydrate is used as an additive in metal-working fluids, which are used during machining processes to prevent corrosion. It also acts as a catalyst for transfer reactions between phosphorus pentoxideFormule :C2H2O4•(H2O)2Degré de pureté :Min. 95%Masse moléculaire :126.07 g/molOxalic Acid extrapure AR, 99.5%
