Chromic acetate Consensus Reports

Chromic acetate Specification

The Acetic acid,chromium(3+) salt (3:1), with the CAS registry number 1066-30-4 and EINECS registry number 213-909-4, has the systematic name of chromium(3+) triacetate. It is a kind of grayish green to bluish green powder, and belongs to the product category of Organic-metal salt. And the molecular formula of this chemical is C₆H₁₂CrO₆. What's more, it is usually used as analytical reagent, mordant and catalyst.

The physical properties of Acetic acid,chromium(3+) salt (3:1) are as followings: (1)ACD/LogP: -0.29; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -1.07; (4)ACD/LogD (pH 7.4): -2.86; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)ACD/KOC (pH 5.5): 2.73; (8)ACD/KOC (pH 7.4): 1; (9)#H bond acceptors: 2; (10)#H bond donors: 1; (11)#Freely Rotating Bonds: 0; (12)Polar Surface Area: 37.3 Å²; (13)Flash Point: 40 °C; (14)Enthalpy of Vaporization: 23.7 kJ/mol; (15)Boiling Point: 117.1 °C at 760 mmHg; (16)Vapour Pressure: 13.9 mmHg at 25°C.

Preparation: Add weak aqua ammonia to the Cr(H₂O)₆Cl₃ solution, and then boil it, then you can get chromic hydroxide. Add superfluous acetic acid, and the reaction will give off a lot of heat. After several hours, it will separate crystals out. Wash it with acetone and ether, and then put it into the sulphuric acid desiccator to make it dry.

You should be cautious while dealing with this chemical. It irritates to eyes, respiratory system and skin. Therefore, you had better take the following instructions: Wear suitable protective clothing, gloves and eye/face protection, and in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice.

You can still convert the following datas into molecular structure:
(1)SMILES: [Cr+3].O=C([O-])C.[O-]C(=O)C.[O-]C(=O)C
(2)InChI: InChI=1/3C2H4O2.Cr/c3*1-2(3)4;/h3*1H3,(H,3,4);/q;;;+3/p-3
(3)InChIKey: WYYQVWLEPYFFLP-DFZHHIFOAC
