深圳外国语学校高三学生李宜临在第40届中国化学奥林匹克初赛中获得广东省一等奖，全省排名第34名1。此次竞赛吸引了全省2800多人参加1。
李宜临对化学的热情源于初三的一堂实验课1。当时一个过氧化氢分解实验激发了他对这门学科的浓厚兴趣，随后他用三年时间进行了系统的学习与实践。在备赛阶段，他通过多种方式深化专业知识，包括在家自制实验、赴高校实验室实操，以及前往重庆、济南、成都、杭州等地参加外培1。其中在四川大学有机实验室，他进行了格氏反应、酯化反应、重结晶等三大经典实验，其中格氏反应在失败两次后终于在第三次成功1。备赛期间，李宜临通读了约十本大学本科和研究生级别的教材1。
在学习方法上，李宜临总结出以错题反思、知识体系构建、精读教材为核心的竞赛学习策略1。他建议学生重视错题背后的原理、搭建完整的知识网络、坚持阅读教材1。展望未来，李宜临计划深耕有机化学与材料化学领域，专注于柔性屏幕、高效电池等前沿材料的研究1。
Li Yilin, a senior at Shenzhen Foreign Language School, achieved first place in Guangdong Province at the 40th Chinese Chemistry Olympiad preliminary round, ranking 34th across the entire province among over 2,800 participants 1. His passion for chemistry was ignited during a junior high chemistry class when he witnessed a hydrogen peroxide decomposition experiment 1.
Over three years of systematic study and practice, Li developed a rigorous learning methodology centered on analyzing mistakes, constructing knowledge frameworks, and thoroughly studying textbooks 1. During his preparation, he read approximately ten university-level and graduate-level chemistry textbooks 1. To gain hands-on experience, he conducted self-made experiments at home and worked in organic chemistry laboratories at universities 1. At Sichuan University's organic laboratory, he performed three major experiments including Grignard reactions, esterification, and recrystallization; the Grignard reaction failed twice before succeeding on the third attempt 1. His training took him to multiple cities including Chongqing, Jinan, Chengdu, and Hangzhou 1.
Looking forward, Li intends to pursue research in organic chemistry and materials science, with interests in areas such as flexible screens and high-efficiency batteries 1.
