英国化学家普利斯特利(J.Priestley)在1774年8月1日做了一个分解“水银灰”(汞的氧化物)的实验,他把透镜聚焦的阳光投射到“水银灰”上,分解出一种气体,比空气的助燃性强许多倍。他把这种气体称作“脱燃素空气”。同年,普利斯特利去法国旅行,把这个发现告诉了法国化学家拉瓦锡。拉瓦锡不相信燃素说,别有见解,但动手重复了这 The British chemist J. Priestley did an experiment on decomposing “Mercury” (mercury oxide) on August 1, 1774, projecting the lens-focused sunlight to the water Silver gray “, decomposition of a gas, many times stronger than the air combustion. He called this gas ”air of delignification ". In the same year, Priestley traveled to France to tell the French chemist Lavoisier about the discovery. Lavoisier does not believe the phlogiston says, do not have the opinion, but hands repeated this
