To explore the ways of organic chemistry experiment teaching reform in pharmacy specialty, and to update the experiment content and make multimedia teaching videos on the premise of ensuring the teaching quality. Strengthen qualitative experiment teaching methods; Select reagents with less toxicity to students and the environment for experiments, increase comprehensive experimental contents, and make full use of/test products. Cultivate students' innovative ability and environmental awareness. As a compulsory basic course for pharmaceutical students, organic chemistry experiment uses a lot of toxic and harmful chemical reagents. With the expansion of colleges and universities, the chemical reagents needed for experiments increase, and the "three wastes" produced by experiments are also increasing. In order to reduce the harm of chemical reagents to students and environmental pollution, the author reformed the organic chemistry experiment without affecting the teaching quality. Making multimedia teaching videos and strengthening qualitative experimental teaching methods. Choose reagents with less toxicity to students and the environment for experiments; Increase the content of comprehensive experiments and make full use of synthetic experimental products; Cultivate students' innovative ability and environmental awareness, and reduce environmental pollution. The experience of organic chemistry experiment reform in recent years is summarized. A, making teaching videos. There are many kinds of chemical reagents needed to reproduce organic qualitative experiments, most of which are toxic and flammable. The experiment takes a long time (the total time is about * * *), and it is difficult to treat the toxic and harmful substances and waste liquid produced by the experiment. Direct discharge will seriously pollute the environment. In order to protect the environment and cultivate students' awareness of environmental protection, we reformed the qualitative experiment teaching and applied for the application of multimedia technology in the experimental teaching of organic compounds. Making the experimental teaching of organic compounds into videos can not only consolidate the theoretical knowledge students have learned, but also reduce the pollution caused by "three wastes". The contents of organic qualitative experiments (qualitative analysis of elements, preparation of acetylene, properties of saturated and unsaturated hydrocarbons, properties of haloalkanes, alcohols, aldehydes and ketones, properties of sugars, amines, carboxylic acid derivatives, amino acids and protein) are recorded and edited by digital video camera. Under the wonderful explanations of teachers, audio-visual discs are made by multimedia technology and played in classroom teaching, which improves the teaching quality and is valued. Minimize the pollution of organic chemistry to the environment, infiltrate the educational concept of green chemistry into the whole process of organic chemistry teaching, and guide students to establish a high sense of responsibility for protecting the natural environment and the sustainable development of mankind. B, choose the experimental content that reflects environmental awareness. When choosing the teaching content of organic experiment, we should fully consider the toxicity of chemical reagents, intermediate products and final products, try not to use or use less experimental items that are toxic to reagents and difficult to treat the three wastes, and choose experimental items with low toxicity, little pollution and easy post-treatment for experimental teaching. For example, canceling the synthesis experiment of nitrobenzene and conducting vacuum distillation experiment with water as reagent can also enable students to master the technology of vacuum distillation. The synthesis experiment of cinnamic acid instead of aniline also enabled students to master the operation of steam distillation. The preparation experiment of cyclohexyl chloride with less toxicity was selected and the fractionation operation technology was practiced. Organic experiment teaching not only pays attention to cultivating students' operation skills, but also embodies the awareness of environmental protection. Waste utilization to cultivate students' awareness of environmental protection. Pay attention to cultivating students' awareness of environmental protection in organic experiment teaching, minimize the waste of resources and realize the recycling of resources. In the preparation of acetophenone, students are allowed to distill and recover the benzene waste liquid produced by themselves, which can be recycled after distillation. The hydrogen chloride gas produced in the process of synthesizing acetophenone and cyclohexyl chloride is absorbed by a simple gas absorption device to make it neutral and harmless. Recovering acetanilide synthesized by night university and correspondence students for recrystallization experiment. All intermediate products and final products synthesized by students are recycled, such as recycled cyclohexane and cinnamic acid for students' graduation design and teachers' scientific research. Set up comprehensive experiments, combine two or more synthetic reactions, embed toxic and harmful intermediates into non-toxic final products, and recover experimental products. While cultivating students' comprehensive skills, it also reduces environmental pollution. At the same time, comprehensive experiments can make students make full use of what they have learned, develop their knowledge potential and improve their ability to analyze and solve problems. In the glassworker's operation experiment, students are required to practice dropper and capillary B with corner waste of bent elbow. Collect qualified elbows, droppers and used rubber plugs for future experiments or for analytical chemistry and physical chemistry experiments. Collect the mercury in the thermometer broken by the students in a bottle filled with water and seal it. From basic courses to specialized courses, pharmaceutical students have experienced the continuity and cohesion of the whole experimental teaching and experimental skills in different disciplines, and their awareness of environmental protection has been consolidated and strengthened. D. Popularize new experiments and realize the reform of green chemistry. Green chemistry is a science that uses chemistry to prevent pollutants. Its research purpose is to reduce or eliminate the use and generation of harmful substances in the design, manufacture and application of chemical products through a series of principles and methods, so as to make the chemicals involved more friendly? . The opening of the new experiment is derived from the concept of green chemistry. In organic chemistry experiments, the dosage of reagents should be reduced as much as possible to reduce environmental pollution. Micro-chemical experiments provide a feasible direction for the reform of organic experiments with high toxicity, high reagent consumption and serious environmental pollution. Using as few reagents as possible to obtain accurate and obvious experimental results, cultivate students' observation ability and scientific and technological innovation ability, and also enhance students' awareness of environmental protection. By means of computer simulation, students can simulate experimental projects with high toxicity and difficult treatment of three wastes, such as the preparation of nitrobenzene and aniline. Students can not only observe the experimental phenomena and operations, but also avoid the discharge of toxic and harmful substances. In research experiments and design experiments, we should choose some research topics about the design of clean synthesis process, the synthesis of useful compounds in factories and the treatment of "three wastes". Infiltrating green chemistry education in organic chemistry experiment teaching is conducive to the improvement of students' comprehensive quality and experimental skills, and to the cultivation of students' environmental awareness. Higher education shoulders the heavy responsibility of cultivating innovative talents with the concept of sustainable development and being able to deal with the relationship between man and nature by using science and technology. In organic experiments, reducing environmental pollution as much as possible not only improves students' innovative ability, but also enhances students' awareness of environmental protection and social responsibility.
