Properties and stability

This product is highly toxic. It is easily absorbed through the skin and is easily decomposed into formaldehyde and hydrocyanic acid, so it is almost as toxic as hydrocyanic acid and can cause headaches, dizziness, nausea, vomiting, weakness, ataxia, and elevated body temperature. Cyanide can be found in the blood. The oral LD50 for rats is about 8 mg/kg. It is very toxic to the human body. Even if it is not inhaled, it can be fatal when it is splashed on clothes. The workplace should have good ventilation, equipment should be sealed, and operators should wear protective equipment.

Storage method

This product is stored and transported according to the regulations on toxic and dangerous goods.

Synthesis method

1. Obtained from the reaction of formaldehyde and potassium cyanide. Slowly add 37% formaldehyde aqueous solution dropwise to the potassium cyanide aqueous solution, and control the temperature not to exceed 10°C. After standing for 10 minutes, while still stirring below 10°C, add dilute sulfuric acid until the pH is 1.9. Then add 5% potassium hydroxide solution dropwise until the pH is about 3.0, then add diethyl ether, and filter out the generated potassium sulfate. The filtrate was extracted with diethyl ether. After drying, the ether is evaporated, the residue is distilled under reduced pressure, and the fraction at about 100°C (1.33kPa) is collected to obtain the finished product. 2. Produced by the reaction of formaldehyde and hydrocyanic acid in the presence of a catalyst. In addition, hydroxyacetonitrile can also be produced from ethanol and ammonia through gas phase catalysis.

Purpose

Organic synthetic raw materials. It can be used as an intermediate for the production of glycine, malononitrile and indigo dye.
