Course description and aims

[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.

Student learning outcomes

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.

Keywords

Class flow

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.
