He received a Ph.D in Synthetic Organic Chemistry, where he researched innovative organic synthesis towards sustainable manufacture of Active Pharmaceutical Ingredients (API). Topics included visible light photocatalysis, radical chemistry, electrochemistry and flow chemistry. Based within the Global API Process Chemistry department at GlaxoSmithKline (GSK), he specialised in tools for reaction optimisation such as statistical modelling (DoE), parallel experimentation and automation.

Why do you use SAIDA’s reactor?
SAIDA’s reactor is a new commercial flow reactor which uses Microwave heating technology. This type of flow reactor is ideally suited to the safe operation of chemical reactions which, in batch, normally require elevated temperatures and extended reaction times.
What is the merit or strong point of SAIDA’s reactor compared to another reactors?
Firstly, whilst microwave-heated batch reactions are generally unsuited to scale-up, SAIDA’s reactor benefits from continuous flow technology. This allows high temperature reactions to be conducted in a controlled, scalable and safe manner. Uniform, autotunable microwave heating and flow processing mitigate the risks of thermal runaway and superheated hotspots, whilst the hazard is minimized due to the reacting volume being kept small at any one time.
Secondly, by virtue of microwave heating technology (rapid heating and cooling), SAIDA’s flow reactor can achieve stable, desired reaction temperatures faster than typical thermal flow reactors. This is particularly valuable to process chemists, since it expedites reaction optimisation (for example, accelerated data acquisition for Design of Experiments (DoE) analysis). In addition, the amount of material wasted during the interval periods is minimised.


Recommendation message for new customers
Comparing to a microwave batch reactor, in terms of control, safety and scalability; SAIDA’s microwave flow reactor is the superior choice. Furthermore, in its current state, SAIDA’s microwave flow reactor performs comparably with commercially available thermal flow reactors and exhibits fundamental, competitive advantages for elevated temperature chemical reactions.
I recommend SAIDA’s Microwave flow reactor to customers who are interested in safe and scalable operation of high temperature chemical processes and particularly to process chemists who are interested in rapid process optimisation.
