One day, the Swedish chemist Berzelius busy in chemistry laboratory experiments, in the evening, his wife Maria for her birthday and entertain friends and relatives. Berzelius immersed himself in the experiment and forgot all about it. Until Maria pulled him out of the lab, he realized that he was hurrying home. On entering the room, the guests have to congratulate him, he didn't wash took a cup of wine. As he poured himself second glasses of wine, he raised his brows and shouted, "Maria, how can you get me the vinegar?"!" Maria and guests are shocked. Maria looked at the bottle carefully, and poured out a cup to taste it. It was all right. It was really sweet peach wine! Berzelius handed down the cup of wine which he poured, and Maria took a drink, and almost vomited it all, and said, "how did the liqueur suddenly turn into acetic acid?"" The guests gathered and watched, wondering what had happened to the "magic cup".

Berzelius found that there was a small amount of black powder in the wine glass. He looked at his hand and noticed that his hands were stained with platinum black when he was grinding platinum in the laboratory. His cup of wine in the excitement of acid. It turns out that the power of wine to acetic acid comes from platinum powder, which accelerates the chemical reaction of ethanol (alcohol) and oxygen in the air, producing acetic acid. Later, people called this action "catalysis" or "catalysis". "Greek" means "solving the bondage".

In 1836, he published a paper in the journal physics and chemistry for the first time to propose the concept of "catalysis" and "catalyst" used in chemical reactions.
