Carbamyl chloride - Preparation Method
Open Data Verified Data
results from the interaction of methylamine with phosgene. The 40% methylamine aqueous solution was vaporized, dried and mixed with phosgene at a ratio of 1:1.3, methylamine at 4 m3 /h and phosgene at a ratio of 8. The speed of 6 r13/h (content of 60% ~ 70%) respectively into the preheater preheating, methyl amine preheating temperature control in 220~260 ℃, phosgene control in 200~240 ℃, the two preheated gases enter the Venturi and are synthesized at 280-300 °c to give methyl carbamoyl chloride. Then, carbon tetrachloride (or chlorobenzene solution) is recycled and absorbed at 0-20 ° C. To obtain about 10% of the carbamoyl chloride in carbon tetrachloride (or chlorobenzene) solution, which is distilled to obtain the finished product.

Carbamyl chloride - Reference Information
| Use | Used as an intermediate for carbamate pesticides |
| Production method | is obtained by the interaction of methylamine and phosgene. The 40% methylamine aqueous solution is vaporized, and after drying, it is mixed with phosgene at a ratio (volume) of 1:1:3, methylamine at 4 m3/h, and phosgene at a speed of 8.6 m3/h (content 60% ~ 70%). The preheating temperature of methylamine is controlled at 220~260 ℃, and the phosgene is controlled at 200~240 ℃. The two preheated gases enter the venturi tube, the gas methylcarbamoyl chloride was synthesized at 280~300 ℃. Then carbon tetrachloride (or chlorobenzene solution) is used for cyclic absorption at 0~20 ℃ to obtain about 10% carbon tetrachloride (or chlorobenzene) solution of methylcarbamoyl chloride, which is distilled and rectified to obtain the finished product. |
