Looking for p-toluenesulfonic acid
The market is wide and there are many kinds of things. Yu Jiu wanted to buy p-toluenesulfonic acid (P-tolylsulfonic Acid), but he searched all over the city, but found no trace.

One day, I heard that Jia people often go to various places and collect strange goods. Yu then visited and explained in detail what he wanted. Jia people frowned and said: "Although this product is not rare, the supply of goods is quite tight recently, and the road to procurement is difficult, and the price is not cheap." Yu Xinxin said eagerly, "But if there is this product, it doesn't matter if the price is high." Jia people nodded and allowed to pay attention.

A few days later, Jia sent a boy to tell him that Yun had a clue that there was one in Yuanyi, or there was a sale of toluenesulfonic acid. Yu didn't give up and went on the journey immediately. When he arrived at his place, he saw that the owner of the house was an old man, kind and kind. I asked him if he had any toluenesulfonic acid, and the old man smiled and said, "The guest officer came by chance, and he just happened to have a little stock, but it wasn't much." Yu Daxi, looking at the goods, they were in good condition, so he agreed to price them and buy them all.

On the way home, my heart was very happy, and I got this pair of toluenesulfonic acid, and everything may be smooth. This time I asked for goods, there were many twists and turns, and fortunately I achieved success, which is really a blessing If you need it again in the future, you should make plans early to avoid the pain of running around.
