Thermal decomposition reaction of acetylacetonato zinc monohydrate in humidity atmosphere

TA-5009: Thermal decomposition reaction of acetylacetonato zinc monohydrate in humidity atmosphere

 

User can study the detail of influenced heating process of raw material by changing water vapor partial pressure in the atmosphere employed TG-DTA connected to the humidity generator.

The traditional TG-DTA can be measured by controlling temperature with time as parameter which has no relation with sample change, on the other hand, SCTG (Dynamic TG ) can be measured by controlling temperature with sample amount change as parameter. Compared Dynamic TG to traditional TG-DTA, it is available to measure with enhancing the resolution and prompting gradual reaction of sample.

We studied the thermal behavior of acetylacetonato zinc monohydrate(C₁₀H₁₄Zn·H₂O)in N₂ atmosphere which controlled various water vapor concentrations by TG-DTA measurement.

TG-DTA is a hyphenated technology generally referred to as simultaneous thermal analysis (STA).

 

 

DSC is a thermal analysis technique that quantifies the amount of energy in a reaction.

Quantifies the energy changes in reactions such as melting, transition, crystallization and glass transition temperature.

DSC8271 is a high-temperature type DSC with a maximum temperature of 1,500°C.

TMA is the measurement of a change in dimension or mechanical property of the sample while it is subjected to a controlled temperature program.

 

The compact humidity generator (HUM-1) is connected to the TG-DTA for measurements under constant relative humidity water vapor atmosphere.

 

TMA/HUM measures change in dimension or mechanical property of a sample while subjected to a temperature regime under water vapor atmosphere with a constant relative humidity.

Thermo Mass Photo combines simultaneous thermal analysis with mass spectrometry. This technique is suitable for the qualitative analysis of  evolved gases coincident with the STA signal.

In TG-FTIR, gases evolved by volatilization or thermal decomposition are qualitatively analyzed, which allows you to track changes in the generated amount along with the temperature change.
