Reaction calorimeter - High pressure laboratory reactor with in situ FTIR and probe for in-process particle characterization

Name / equipment: RC1e Reaction calorimeter  

Manufacturer / Brand: Mettler Toledo  

Model:   RC1e – Reaction calorimeterFTIR – ReactIR 45mFBRM – Lasentec D600 tip L

Scope of usage: RC1e is a high performance thermostat allowing the development of chemical processes under the same conditions as in production. RC1e is software controlled. Temperature of entire process is precisely controlled and measured, dosing is balance controlled and pressure is controlled by automatic valve. Thermal interval for synthesis depends of thermostatic liquid and reaction vessel that is used and is from -90 ° C to +250 ° C. In addition to controlling the process parameters RC1e allows us measurements of thermodynamic properties of products and processes (exothermicity, endothermicity of process, cp of reactants and products).

Chemical processes and thermodynamic parameters can be studied on the following reactors:

-        AP01-2: 2,5L glass reactor vessel with a working volume between 0,5-2,0L, temperature range is between -53°C and +200°C reactor pressure between 0,05 bar to normal

-        AP01-2-RTC:  2,47L glass reactor vessel with a working volume between 0,6-2,0L, temperature range from -50°C to +162°C and reactor pressure from 0,05 bar to ambient

-        HP60: 1,8L stainless steel reactor vessel with a working volume between 0,5-1,5L, temperature range between -10°C and +250°C and reactor pressure from high vacuum to maximum 60 bar.

-        AP00-0.1: 100mL glass reactor vessel with working volume between 30-80mL, temperature range from -53°C to +200°C and reactor pressure from 0,05 bar to ambient

In case of removal or partial removal of solvents distillation / reflux set can be used on any of abovementioned vessels. Chemical reactions can be monitored in situ with ATR FTIR spectroscopy with by in vessel immersed probes:

-        K6 Dicomp 16mm probe for HP60 reactor vessel (usable detection intervals 650–1800 cm-1 and 2400–4000 cm-1)

-        K6 Sicomp 16mm probe for AP01-2 or AP01-2-RTC reactor vessels (usable detection intervals 650–4000cm-1)

-        Optical fiberglass AgX 9,5mm Dicomp probe for AP01-2, AP01-2-RTC in AP00-0.1 vessels (usable detection intervals 650–1800 cm-1)

Physical processes of particle changing (exp. crystallization or dissolution) can be monitored in situ by FBRM method (Focused Beam Reflectance Measurment). There are some restrictions of FBRM analysis due to measurement technique: measurement interval is between 500nm and 3mm of particle size.  

Examples of application for polymer analysis / information that can be obtained by this method for polymers: RC1e is useful and a powerful tool for chemical and technological studies of processes and chemical reactions, industrial scale up, reaction mechanisms, process optimizations…
