Learning objectives
The course is aimed at:
- provide in-depth knowledge on the most important chemical processes
- provide basic knowledge on chemical process plants: design, management, safety
- provide adequate knowledge on the economic evaluation of a chemical process
- provide comparative and critical evaluations on the environmental sustainability of the process
- provide in-depth knowledge on the main classes of chemical formulas
- provide in-depth knowledge on the ingredients of chemical formulations (synthesis and chemical-physical properties)
- provide a comparative and critical evaluation of the most known formulations on the market
The conceptual tools are provided for a critical understanding of industrial production processes with regard to:
- choice of the process, the plant and the technology to be applied to obtain a chemical intermediate
- choice of the process and the ingredients to be applied to obtain a chemical formulation
- evaluation of total costs
- environmental and safety issues
-problematic related to the packaging materials of intermediates and formulated
The links between the different parts of the course and with courses already followed by the students in previous years and in the current year are highlighted, with particular reference to the contents of physical, organic and industrial chemistry.
The student must be able to evaluate the choice of the process, of the industrial feedstock, of the catalysts, of the technology, of the operating conditions; to understand issues related to production, environmental and safety costs.
During the course, the autonomous judgment and the discussion on the issues are stimulated, with the use of online bibliographic research from accredited sources of primary literature.
The student have to develop autonomous skills that allow him to evaluate, compare, criticize and weigh negative and positive aspects of the industrial chemical processes analyzed, and to think about possible pilot-scale innovations on the market.
The acquisition of a formally correct language is required, the ability to express content in a clear and linear way is encouraged.

Teaching methods
The course takes place in 72 hours of lessons, which will be organized face to face with the possibility of attending the lessons in asynchronous mode at distance (lessons uploaded on the Elly page of the course and on teams); discussion and exercises will be organized for the students who follow remotely (in small groups by appointment on Teams platform).
The slides used during the lessons and other supporting material will be uploaded every week on the Elly platform. To download the slides you need to register for the online course. The slides are considered an integral part of the teaching material.
Non-attending students are reminded to check the teaching material available and the information provided by the teacher through the Elly platform. The teacher is available by appointment (e-mail) for clarification, both remotely and in person.
The course makes use of one or more expert seminars and possibly educational visits to chemical plants that will be promptly communicated to students.
Assessment methods and criteria
The acquired knowledge and the ability to understand the concepts treated are verified through an oral examination during which the student must demonstrate that he has understood the chemical processes treated and that he can compare and discuss them in an independent and critical way.
For formulations, a lesson will be or prepared by students, as flipped classroom, i about a topic assigned by the teacher during the lesson period; it is requested to explain by a critical and original presentation on a commercial formulation, analyzing the individual ingredients, their production and their environmental sustainability in relation to the cost and disposal of the product and its packaging.
The assessment of learning takes place with two separate exams that affect the final score in the following proportions:
Processes: up to a maximum of 15 points
Formulations: up to a maximum of 15 points (max 8 points for fliipped classroom lesson)
Process:
A oral test consisting of 9 questions concerning all the topics of the course. Each question has a specific maximum score ranging from 0 to 2.
Examples of questions and exercises will be discussed during lessons.
Formulations:
The student is asked to prepare a multimedial discussion on a commercial formulation, focusing on role issues, and chemical synthesis of ingredients, cost, life cycle, packaging and safety issues for the environment and the health, together with a written critical report, and to present then to the class. Some additional questions on the course programme will be done during the oral exam.
The laude is awarded in the case of the achievement of a score of 30 only if the candidate demonstrates the ability to argue critically and the ability to connect the different parts of the course. The skills of synthesis, use of a correct technical language and communication will be evaluated positively.
