Appearance: colorless liquid with a chloroform-like odor. Logarithm of the octanol / water partition coefficient: 2.88 Solubility: insoluble in water, soluble in alcohol, ether, etc. Most organic solvents. [3] is a colorless, transparent liquid factory direct tetrachlorethylene, with similar ether odor. Can dissolve a variety of substances (such as rubber, resins, fats, aluminum trichloride, sulfur, iodine, mercuric chloride). Miscible with alcohol, ether, chloroform, benzene. Was dissolved in about 10,000 times the volume of water. [4] The molecular structure of the data: 1 molar refractive index: 30.45 2, molar volume (m3 / mol): 100.3 3, isotonic hematocrit (90.2K): 245.0 4, surface tension (dyne / cm): 35.6 5, polarization rate (10-24cm3): 12.07 [5] of inorganic ions with biological probes substitute some other metal elements in the original bio-inorganic compounds of metal elements PCE uses bio-inorganic chemistry, which use a variety of spectroscopic methods to study and determine the Structure and function of the system. The use of metal ions called biological probes. Used as a probe of the original metal ions should have similar ionic radii tetrachlorethylene price, and can maintain a certain structural features and biological activity of the original system. For example, with a radius similar to zinc cobalt ions as a probe, instead of carboxypeptidase zinc, thereby infer carboxypeptidase zinc coordination environment based on the spectrum of cobalt-containing enzymes; manganese ions with a probe, based on manganese NMR spectrum carboxypeptidase carboxypeptidase identified zinc and a water molecule or a hydroxyl group attached.
