Specification
The Yttrium Nitrate Hexahydrate, with the CAS registry number 13494-98-9 and EINECS registry number 233-802-6, has the systematic name of yttrium nitrate hydrate (1:3:6). It is a kind of white adhering crystals or crystalline powder, and belongs to the following product categories: Metal and Ceramic Science; Salts; Yttrium Salts. And the molecular formula of this chemical is YN3O9.6H2O. What's more, it should be stored at 0-6°C.
The physical properties of Yttrium Nitrate Hexahydrate are as followings: (1)ACD/LogP: -0.13; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -0.13; (4)ACD/LogD (pH 7.4): -0.13; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)#H bond acceptors: 4; (8)#H bond donors: 1; (9)#Freely Rotating Bonds: 0; (10)Polar Surface Area: 66.05 Å2; (11)Enthalpy of Vaporization: 37.72 kJ/mol; (12)Boiling Point: 83 °C at 760 mmHg; (13)Vapour Pressure: 49.8 mmHg at 25°C.
The preparation of Yttrium Nitrate Hexahydrate: Excessive Y2O3 react with hot concentrated nitric acid. After filtration, remove unreacted oxide, then by cooling crystallization, suction filtration and drying, you can get the product.
