12. Conclusions
An energy balance & transfer functions were utilized to control temperature and time in the process via feedback control
The transfer function was modeled in Simulink & displays a graph that demonstrates the desired results for the temperature over time
This process control allows for the use of ethyl 3-(cyclohex-1-en-1- yl)propionates to improve fragrance formulation
