且说化学史上有一段长达一千多年的漫长而黑暗的时期,那就是炼丹和炼金时代。在我国先秦时期的一本叫《战国策》的古书中,就有方士们向荆王献“不死之药”的记载。这是关于炼丹的早期记录。电视剧《西游记·大闹天宫》中,有一段讲太上老君的兜率宫中炼丹的情景,可说是炼丹的形象写照。炼丹就是用硫黄、辰砂、水银等物质为原料,经过复杂的加工炼制过程,制得一种不仅能包治百病,还能使人长生不老的“金丹”,或叫“仙丹”。吃了 And that the history of chemistry for a long period of more than a thousand years of dark and long period, that is alchemy and alchemical era. In the ancient books called “Warring States Policy” in the pre-Qin period of our country, there were records of alchemists offering “undead medicine” to King Jing. This is an early record of alchemy. In the TV series “Journey to the West”, there is a passage in the palace that tells the story of Alchemy on the Taoist Lao Tzu. It is a portrayal of alchemy. Alchemy is the use of sulfur, cinnabar, mercury and other substances as raw material, after a complex process of refining and refining, not only can cure a hundred diseases, but also make people immortal “saver,” or “elixir.” have eaten
