Summary of "Thermotropic Phase Transitions in Butyltrimethylammonium Bis(Trifluoromethylsulfonyl)Imide Ionic Liquids Are Dependent on Heat Flux."

Transmission Infrared Spectroscopy (IR) and Differential Scanning Calorimetry (DSC) are used to identify and characterize multiple phase transitions of butyltrimethylammonium bis(trifluoromethylsulfonyl)imide ([N1114] [TFSI]). Phase dependent properties are analyzed using temperature-controlled transmission IR, in which we identify changes in the molecular arrangements at and around phase transition temperatures between -80° C and 30° C, which span crystallization and melting phase transitions. Our data report the dependence of phase transition behavior across multiple heat flow rates and the resulting molecular organizations that are formed. This is significant as temperature specific organizations and properties of ionic liquids contribute significantly to their application in separations and in devices. We also identify and discuss the relationship between phase transitions temperatures and classes of those transitions when various temperature ramp rates are applied. Our analysis indicates that these relationships of IL thermochemistry could be developed as a diagnostic for assigning phase transition types.

Medical and Biotech [MESH] Definitions

Salts that melt below 100 C. Their low VOLATILIZATION can be an advantage over volatile organic solvents.

Technique by which phase transitions of chemical reactions can be followed by observation of the heat absorbed or liberated.

A cyclin subtype that has specificity for CDC2 PROTEIN KINASE and CYCLIN-DEPENDENT KINASE 2. It plays a role in progression of the CELL CYCLE through G1/S and G2/M phase transitions.

The interval between two successive CELL DIVISIONS during which the CHROMOSOMES are not individually distinguishable. It is composed of the G phases (G1 PHASE; G0 PHASE; G2 PHASE) and S PHASE (when DNA replication occurs).

Functionalization of exogenous substances to prepare them for conjugation in PHASE II DETOXIFICATION. Phase I enzymes include CYTOCHROME P450 enzymes and some OXIDOREDUCTASES. Excess induction of phase I over phase II detoxification leads to higher levels of FREE RADICALS that can induce CANCER and other cell damage. Induction or antagonism of phase I detoxication is the basis of a number of DRUG INTERACTIONS.
