摘　　要：立足课堂教学中化学学科核心素养的落实,基于“结构决定性质”的学科思想观念,以探究防晒霜的有效成分为主题,从肉桂酸的防晒性能入手,探究肉桂酸的结构、修饰其结构、完善其性能、设计与评价对甲氧基肉桂酸-2-乙基己酯的合成路线。使学生切身体会到化学学科知识的应用价值,增强学生应用化学知识解决实际问题的能力。Based on the implementation of the core quality of chemistry in classroom teaching and the idea of"structure determines nature",this paper studies the effective components of sun-screen,and starts with the sunscreen performance of cinnamic acid,to study the structure of cin-namic acid,modify its structure,improve its properties,design and evaluate the synthesis of p-methoxycinnamic acid-2-ethylhexyl ester.It makes the students realize the applied value of chem-ical subject knowledge,and enhances the students'ability to solve practical problems with chem-ical knowledge.
