[Description of the course] In this course, the instructor will give instructions on basic tasks of chemical experiments for sophomore students who studied Chemical Engineering and Industrial Chemistry Laboratories I a/b and I b/a, to cultivate their skills in experimental tasks and their understanding of organic chemistry, inorganic chemistry, and analytical chemistry. From the viewpoint of a practical chemical industry education, two themes are set following Chemical Engineering and Industrial Chemistry Laboratory II a/b; (1) “synthesis and dyeing of azo compound”, for learning pigment synthesis as a model of dye industry, and (2) “synthesis and composition analysis of ferrite”, for learning synthesis of the magnetic material which was invented in our institute and has been studied as advanced materials today, and demonstration of magnetic recording.
[Aim of the course] For understanding the connection of basic chemistry and materials society, it is essential to deeply examine the experimental results obtained by synthesis reaction through analyses and comprehension. One must learn fundamental tasks with certainty and then approach the experiments with the underlying principles of reactions and safety. In this experiment, students first learn the essentials of fundamental tasks in a lecture and experimental presentation. Then, they practice fundamental tasks while going through the three themes. Examinations on basic knowledge and practical thinking as well as writing experimental reports for each theme will enable the students to acquire correct synthetic and analytical techniques and to cultivate discussion skills.
At the end of this course, students will be able to:
1) apply fundamental operations such as filtration, washing, drying, vacuum distillation, and so on to a number of unit processes.
2) complete a general style of the experimental report including results, discussions, and survey details.
3) explain historical background and practical materials related to each theme.
4) acquire systematic knowledge from experiments and to develop a plan for a safe and productive chemical experiment.
(synthesis and dyeing of azo compound) azo dye, diazotization reaction, diazo coupling, Lambert-Beer law, dyeing, ultraviolet and visible absorption spectrum, fiber (natural/artificial polymer),
(synthesis and composition analysis of ferrite) ferrite, Ellingham diagram, control of non-stoichiometry, magnetic susceptibility, thermogravimetric analysis, density measurement
|✔ Specialist skills||Intercultural skills||Communication skills||Critical thinking skills||✔ Practical and/or problem-solving skills|
In this course, all the students will start with (1) experimental presentation. Then, the students are divided into two groups to learn the following two experiments in turn: (2) synthesis of azo compound and dyeing, and (3) synthesis and composition analysis of ferrite. In the last day, exercise problems and interpretation of the answers will be given to assess the students’ level of understanding.

To enhance effective learning, students are encouraged to spend approximately 50 minutes preparing for class and another 50 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
Textbook for the Chemical Engineering and Industrial Chemistry Laboratory II 2019 (In Japanese), edited by committee for the chemical engineering and industrial chemistry laboratory (Tokyo Institute of Technology, School of Materials and Chemical Technology, Department of Chemical Science and Engineering). This textbook will be distributed during the first class.

Students will be assessed on their achievements of learning outcomes based on the quality of reports on two themes (83%) and examination (17%).
A student may fail the course if he/she repeatedly comes to class late or does not submit assignments too often.
The prerequisite to take this course is that you have acquired the credits of "Chemical Engineering and Industrial Chemistry Laboratory II a/b".
Without having acquired the credits of the above course, the credits of this course will not be counted as the necessary number of credits for graduation.
Students must have successfully completed both Chemical Engineering and Industrial Chemistry Laboratory I a/b (CAP.B201.R) and Chemical Engineering and Industrial Chemistry Laboratory I b/a (CAP.B202.R) or have equivalent knowledge.
