Hydroxyacetonitrile - Safety
Open Data Verified Data
This product is highly toxic. Easily absorbed through the skin, because it is easy to decompose into formaldehyde and hydrogen cyanide, so it has almost the same degree of toxicity with hydrogen cyanide, can cause Head Pain, dizziness, Nausea, Vomit, weakness, ataxia, temperature increased. Cyanide is found in the blood. The oral LD50 for rats is about 8 mg/kg, and the toxicity is very strong, and even if it is not inhaled, it can be lethal to the human body when it is splash on the clothes. Workplace should have good communication

| use | organic synthetic raw materials. It can be used as an intermediate for the production of glycine, malononitrile, and indigo dyes |
| production method | 1. It is obtained by the reaction of formaldehyde and potassium cyanide. Slowly add 37% formaldehyde aqueous solution to potassium cyanide aqueous solution, and control the temperature not to exceed 10 ℃. After standing for 10min, stir below 10 ℃ and add dilute sulfuric acid to pH 1.9. Then add 5% potassium hydroxide solution dropwise to a pH of about 3.0, then add ether, and filter the produced potassium sulfate. The filtrate was extracted with ether. After drying, the ether is evaporated, the residue is distilled under reduced pressure, and the fraction at about 100 ℃(1.33kPa) is collected to obtain the finished product. 2. It is prepared by reacting formaldehyde and hydrocyanic acid in the presence of a catalyst. In addition, hydroxyacetonitrile can also be prepared by gas phase catalysis of ethanol and ammonia. |
