1. Obtained from the reaction of N-formanilide and dimethyl sulfate. Mix N-formanilide and dimethyl sulfate, add potassium hydroxide solution dropwise while stirring and cooling, and control the temperature below 15°C. After the dropwise addition is completed, continue stirring for 1 hour at 20-25°C. The reaction mixture becomes slightly alkaline. Slowly add concentrated ammonia solution dropwise to decompose excess dimethyl sulfate. Then let it stand for layering, take the upper oil and distill it under reduced pressure, and collect the 130-133°C (2.13kPa) fraction, which is N-methylformanilide, with a yield of about 90%.

2. Obtained from the reaction of N-methylaniline and formic acid. Mix N-methylaniline, formic acid and toluene, heat and distill, and after steaming out the water, raise the temperature to 108-110°C to steam out the toluene. The residue is distilled under reduced pressure to obtain the finished product.

1. Ethanol alkylation method: Fill a fluidized bed reactor with a capacity of 400 parts with H3PO4-SiO2 catalyst, with an internal surface area of 400m²/g and a H3PO4 content of 10%. In the quartz evaporator installed at the lower part of the fluidized bed, evaporate 110 parts of the mixture of the following composition at 250°C, namely 66% o-toluidine and 34% ethanol [ratio 1:1.2 (molar ratio)]. The fluidized bed is heated to 330°C. 108 parts of condensate were obtained per hour, in which the content of N-ethyl o-toluidine was 60.0 parts, the content of N,N-diethyl o-toluidine was 10.7 parts, and the content of N, N-diethyl o-toluidine was 10.7 parts, and it also contained 14.5 parts of o-toluidine. The conversion rate was 80%, 82.5% of the reacted o-toluidine was converted into N-ethyl o-toluidine, and 13.1% was converted into N, N-diethyl o-toluidine. Alkylating agent ethanol is converted into ethylene by 5%.

2. Ethyl bromide alkylation method: Add 40 mL (0.37 mol) of o-toluidine (0.37 mol) and 14 mL (0.185 mol) of ethyl bromide to a 250 mL three-necked flask. After heating and refluxing for 2 hours, oxidize with 40% hydrogen. Sodium solution is alkalized. Then add a solution of 18.5g zinc chloride (0.136mol) and 20mL of water, and stir for 2.5h. Filter, and continuously extract the filtered solid with petroleum ether in a Soxhlet vessel. Wash the extract with dilute ammonia and distilled water, evaporate the petroleum ether, and distill the residual liquid under reduced pressure. Collect the 105~110°C (4.67kpa) fraction to obtain 21.1g. The yield of the finished product is 85% based on ethyl bromide.
