1894 in science

Diazomethane is an organic chemical compound with the formula CH2N2, discovered by German chemist Hans von Pechmann in 1894. It is the simplest diazo compound. In the pure form at room temperature, it is an extremely sensitive explosive yellow gas; thus, it is almost universally used as a solution in diethyl ether. The compound is a popular methylating agent in the laboratory, but it is too hazardous to be employed on an industrial scale without special precautions. Use of diazomethane has been significantly reduced by the introduction of the safer and equivalent reagent trimethylsilyldiazomet

overview of natural science-related events during the year of 1894

The Lurgrotte karst cave is the largest cave in the Eastern Alps of Styria, Austria. It is located about north of Graz and crosses the Tannenben karst region. The cave has two accessible entrances, one at the village of Semriach and the other at the village of Peggau. At the Semriach entrance, the Lurbach River sinks into the cave. At the Peggau entrance, the Schmelz River emerges from within the cave, flowing to the west and eventually joining the Mur River.
