IMPROVEMENTS IN THE MANUFACTURE OF 4-CHLORO-2-BUTYNYL-¹n-(3-CHLOROPHENYL) CARBAMATE |
| abstract |
In the process for manufacturing 4-chloro-2-butynyl m-chlorocarbanilate (the herbicide barban) from the corresponding 4-hydroxy-2-butynyl m-chlorocarbanilate it has been discovered that yields and product quality are improved by employing dimethylformamide as reaction promoter in combination with thionyl chloride or phosgene as chlorinating agent.n[US4012433A] |
