Chemists are more likely to develop novel materials and processes, while chemical engineers are more likely to take these materials and processes and upscale them to make them larger or more efficient.
Actually chemistry deals with the mechanistic approach of synthesis of either organic or Inorganic compounds . Chemical Engineering converts this art of synthesis into industrial scale or larger scale by using various industrial equipments known commonly known as Unit operations .
Chemisty is one of the main physical sciences,i.e., organic,inorganic,physical chemistry, and so on, which depends upon basic principles; of exact (empirical/Theoretical) solutions,exact mass/energy balance of not only pure matters, but also matters in different phases, i.e. gas,liquid, and solid.
In contrast, chemical engineering is one of the applied branches of physical sciences which dependes upon applied technologies of finding; approximate solutions of mass/energy balance of not only pure matters, but also matters in different phases, i.e. gas,liquid, and solid.
Chemistry deals with study of structure and properties of various chemicals whereas, chemical engineers utilise them in technology (production of useful final product, solving numerous issues in terms of heterogeneous catalysis and many more to count).
The fundamental difference between chemistry and chemical engineering is depending on originality and scale. Chemistry is mainly deal to develop novel materials and processes, while chemical engineering more likely focused on taking these materials and methods and upscale them to make them larger or more cost-efficient for people.
Most certainly. Chemistry is a basic science and chemical engineering is set of procedures and operations required to make the chemistry happen in a large or industrial scale. Chemistry let us know if say a chemical reaction is feasible and under what conditions. Chemical engineering operationalizes it. If chemistry proves that something is not feasible thermodynamically or kinetically then no amount of chemical engineering is going to help. Not all processes achievable in the lab can be scaled up to be a manufacturable product.
