摘要： 在甲基橙合成原型实验的基础上，将自制的“自动化加料和数字化控温”装置引入实验中，增加了实验安全性，避免了由人力加料导致的反应不均匀、副反应过多等问题，优化了实验流程，提升了实验安全性。在实现原教学目标基础上，使学生能专注于实验现象的观察以及对实验原理的理解，更侧重学生素质能力提升。

Abstract: Building upon the conventional methyl orange synthesis experiment, this study incorporates a self-developed “automated feeding and digital temperature control” system into the experimental procedure. This advancement substantially improves experimental safety by addressing issues such as uneven reaction distribution and excessive side reactions resulting from manual feeding, while simultaneously streamlining the workflow. In addition to fulfilling the original pedagogical objectives, this modified approach enables students to concentrate on observing experimental phenomena and understanding fundamental principles, thereby placing greater emphasis on developing students’ comprehensive competencies.

Key words: Automation technology, Temperature control, Digitalization of chemical experiments
