Abstract:

Alcohol gel for hand-washing disinfection is a kind of daily chemical which has 75% alcohol. It belongs to the category of fine chemicals and is prepared by adjusting the viscosity of alcohol with a thickener. It has played an important role in the fight against the COVID-19 pandemic, and is familiar to people. The basic formula is simple and the ingredients are easy to obtain. Although the production process is simple, the experiment is still a bit difficult. Thus, the preparation process is very suitable for designing the teaching content of "Fine Chemical Laboratory" or similar courses. By setting up this experiment in applied chemistry specialty or related majors, the course can not only enhance students' professional interest in the fine chemical industry, but also cultivate theirs ability to design product formula and practical experience. At the same time, the course also contains many ideological and political elements, which is very suitable for carrying out ideological and political education in laboratory course. Through this course, we can enhance students' awareness of preventing COVID-19 infections, and strengthen their confidence to Chinese characteristic socialism.

Key words: Fine chemical laboratory, Alcohol gels, Experimental design, Ideology and politics education
