Fast screening of polycondensation catalyst, Determination of the kinetic data of catalyzed polycondensation in polyethylene terephthalate synthesis
Differential scanning calorimetry (DSC) belongs to the family of thermal analysis methods. In general thermal analysis is the determination of substance properties in dependence on temperature. Thermodynamic data (heat capacity, phase transition, enthalpy) and kinetic data can be determined by methods of thermal analysis. The greatest advantage of thermal analysis is the easy handling and the o...
متن کاملBone Formation from Porcine Dental Germ Stem Cells on Surface Modified Polybutylene Succinate Scaffolds
Designing and providing a scaffold are very important for the cells in tissue engineering. Polybutylene succinate (PBS) has high potential as a scaffold for bone regeneration due to its capacity in cell proliferation and differentiation. Also, stem cells from 3rd molar tooth germs were favoured in this study due to their developmentally and replicatively immature nature. In this study, porcine ...
متن کاملSafety assessment of modified terephthalate polymers as used in cosmetics.
The safety of 6 modified terephthalate polymers as cosmetic ingredients was assessed. These ingredients mostly function as exfoliants, bulking agents, hair fixatives, and viscosity-increasing agents-nonaqueous. Polyethylene terephthalate (PET) is used in leave-on products up to 100% and in rinse-off products up to 2%. The Cosmetic Ingredient Review Expert Panel (Panel) considered that the PET u...
متن کاملBis(2-hydroxyethanaminium) terephthalate
The asymmetric unit of the title salt, 2C(2)H(8)NO(+)·C(8)H(4)O(4) (2-), comprises one crystallographically independent 2-hy-droxy-ethanaminium cation and one half terephthalate anion. In the crystal, hydrogen bonds involving the hy-droxy and ammonium groups of the cations and the carboxyl-ate O atoms of the terephthalate anions result in the formation of a three-dimensional network structure.
متن کاملTetramethylammonium hydrogen terephthalate
The asymmetric unit of the title salt, C(4)H(12)N(+)·C(8)H(5)O(4) (-), contains one half of a tetra-methyl-ammonium cation and one half of a hydrogen terephthalate monoanion. The N atom of the ammonium cation lies on a twofold rotation axis and the centre of mass of the terephthalate anion is on a centre of inversion. In the crystal, the centrosymmetric terephthalate ions are linked by a very s...
