N-(2-TOLYL)FORMAMIDE - Reference Information
| Production method | 1. It is obtained by the reaction of N-formanilide and dimethyl sulfate. N-formanilide and dimethyl sulfate are mixed, and potassium hydroxide solution is added dropwise under stirring and cooling, and the temperature is controlled below 15 ℃. After dropping, continue stirring at 20-25 ℃ for 1h, and the reaction mixture is slightly alkaline. Slowly add concentrated ammonia water to decompose excessive dimethyl sulfate. Then let it stand and stratify, take the upper oil and distill under reduced pressure, and collect the 130-133 ℃(2.13kPa) fraction, which is N-methylformanilide, with a yield of about 90%. 2. It is obtained by the reaction of N-methylaniline with formic acid. N-methylaniline, formic acid and toluene are mixed, heated and distilled, and the temperature rises to 108-110 ℃ to evaporate toluene. The residue is subjected to reduced pressure distillation to obtain the finished product. |
