Acidic potassium permanganate reaction of olefins

Olefin acidic potassium permanganate will break down to form oxygen-containing compounds under relatively strong conditions, such as acidic conditions or heating conditions. Can produce acetone and propionic acid. Potassium permanganate is widely used in the pharmaceutical industry. For example, for patients with hemorrhoids, a 1:5000 potassium permanganate solution can be used for sitz baths. In addition, potassium permanganate solution can also be used for cleaning after each bowel movement.

When olefins and potassium permanganate are exposed to strong conditions (acidic or heated), the double bonds are completely broken, and at the same time, the CH on the double-bonded carbon atom is also oxidized and broken to form oxygen-containing compounds.

According to the above theory, for CH3-CH=C-CH3, the double bond in the middle is broken, so the products generated are acetone and propionic acid.

Therefore, 1: Whether the product is a carboxylic acid ketone compound or carbon dioxide depends on the position of the double bond.

Potassium permanganate can be used to treat hemorrhoids

External hemorrhoids usually grow at the edge of the anus and can cause swelling due to friction or moisture. After standing or walking for a long time, people often feel that there is a foreign object outside the anus. When defecating or exercising vigorously, the venous plexus may rupture and form a blood clot. At this time, the anus will be extremely painful and a purple-red swelling will appear. The slightest touch will cause pain. The pain will be aggravated by defecation, sitting, walking, or even coughing.

Therefore, patients with hemorrhoids should keep their bowel movements smooth, develop the habit of defecating on time every day, and eat less spicy and irritating foods; when hemorrhoids occur, they should go to the hospital for treatment in time, do not use medicine indiscriminately, and do not easily believe in certain folk remedies. It is also necessary to treat chronic diseases that can increase abdominal pressure, such as habitual constipation, chronic cough, etc. as soon as possible, reduce strenuous exercise and get adequate rest.

You can take a sitz bath with 1:5000 potassium permanganate solution every night before going to bed or after defecation, or use 60 grams each of Sophora flavescens and Houttuynia cordata, decocted in water and then fumigated and washed, both of which have good effects. If internal hemorrhoids prolapse, they should be immediately pushed back by hand. Generally, proper rest and hot compresses or warm water baths in the anus can relieve the pain. After about a week, the blood clots will be gradually absorbed and the pain will be relieved.
