Vanadyl acetylacetonate Specification
The Oxobis (acetylacetonato) vanadium Ⅳ, with the cas registry number 3153-26-2, has the systematic name of oxovanadium(2+) bis[(2Z)-4-oxopent-2-en-2-olate]. This chemical is practically insoluble and it is sensitive to air and incompatible with strong oxidizing agents. Besides, its product categories are various, including Classes of Metal Compounds; Environmentally-friendly Oxidation; Synthetic Organic Chemistry; Transition Metal Complexes (Environmentally-friendly Oxidation); Transition Metal Compounds; V (Vanadium) Compounds. As to its usage, it is used as organic chemistry reagent. This chemical could be derived from the following equation: 2 V2O5 + 9 C5H8O2 → 4 VO(C5H7O2)2 + (CH3CO)2CO + 5 H2O.
The physical properties of this chemical are as follows: (1)ACD/LogP: 0.29; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 0.29; (4)ACD/LogD (pH 7.4): 0.25; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)ACD/KOC (pH 5.5): 34.16; (8)ACD/KOC (pH 7.4): 31.16; (9)#H bond acceptors: 2; (10)#H bond donors: 1; (11)#Freely Rotating Bonds: 2; (12)Polar Surface Area: 37.3; (13)Flash Point: 71.9 °C; (14)Enthalpy of Vaporization: 49.32 kJ/mol; (15)Boiling Point: 187.6 °C at 760 mmHg; (16)Vapour Pressure: 0.174 mmHg at 25°C.
When you are dealing with this kind of chemical, you should be much more careful and then take some measures to protect yourself. For one thing, it is irritating to eyes, respiratory system and skin. For another thing, it is harmful which may cause damage to health. If by inhalation, in contact with skin and if swallowed, it will be very dangerous. Therefore, you should wear suitable protective clothing, gloves and eye/face protection while using this chemical and do not breathe dust. If in case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
