• Resumen

  • This project is conducted by students during the second semester of their second year in our educational institution. This project constitutes an initiation into research and allows a broadening of knowledge, a development in autonomy, organization, team work, and initiative. It helps prepare the student-engineer for an internship in industry. The experiment is done in student pairs over 5 weeks (three, eight-hour days per week). We introduce experimental design to undergraduate students because such methodology is increasingly important in modern industrial research. The well-prepared chemist will need to apply these concepts easily. Other pedagogical goals include increasing experience in synthetic techniques, scientific rigor to obtain reproducibility in the yield, and using quantitative analysis methods. This project investigates optimizing the synthesis of benzyl-1-cyclopentan-1-ol using experimental design. It is carried out in three steps: first the factors that can have a potential influence on the reaction are screened; second, a factorial design is used to study the interactions between the factors; and finally, response surface methodology is used to optimize the yield.
