Enthalpy /ˈɛnθəlpi/ , a property of a thermodynamic system, is equal to the system's internal energy plus the product of its pressure and volume. In a system enclosed so as to prevent mass transfer, for processes at constant pressure, the heat absorbed or released equals the change in enthalpy.

Characterization method for ionic liquid dissolvability

InactiveCN101470063AImprove solubilityReliable dataWeighing by absorbing componentSolubilityDissolution

A characterization method for the solubility of ionic liquid is applied under atmospheric pressure for testing the function among ionic liquid and gas/gas molecules of volatile organic solvent, which is characterized by comprising: using an object ionic liquid as the sensitive film coat material of a resonator induction zone of a mass sensitive piezoelectric crystal detector; coating an ionic liquid film on the surface of the resonator induction zone; detecting the frequency change of the detector before and after acting with researched gas molecules to represent the function between the researched ionic liquid and the gas. The ionic liquid characterization method can obtain the solubility of ionic liquid in gas/volatile organics, and thermodynamic parameters as enthalpy, entropy, free energy change and the like in dissolution; and can research the function approach between ionic liquid and gas molecules. The measurement method is simple, fast and reliable, which can accelerate the development and application of ionic liquid.

Method for preparing halogen-free low-temperature fire-retardant fiber

InactiveCN103590142ALower decomposition temperatureImprove flame retardant performanceInorganic material artificial filamentsFiberDecomposition

The invention discloses a method for preparing a halogen-free low-temperature fire-retardant fiber, and relates to a method for preparing a self-assembled low-temperature fire-retardant fiber at a room temperature. The invention aims at solving the technical problem that the fire-retardant temperature of the current fire retardant is relatively high. The method comprises the following steps: 1, dissolving titanyl sulfate into water containing sulfuric acid; 2, respectively collocating a copper sulfate solution and a calcium nitrate solution; 3, adding the copper sulfate solution into a titanyl sulfate mixed solution for uniformly stirring, and then adding the calcium nitrate solution for uniformly stirring; 4, standing; 5, filtering; 6, washing; 7 drying. The decomposition temperature of the sulfur-free halogen-free fire-retardant fiber is near 150 DEG C, and the enthalpy value is high. When the sulfur-free halogen-free fire-retardant fiber is used on cotton fabrics, the limiting oxygen index is increased by 30 percent, and the amount of release of smoke is reduced by more than 40 percent. The method belongs to the filed of preparation of fire-retardant fibers.
