Urea → (4-Ethylphenyl) carbamate

Participants

Reaction Steps

The same method as step (6-1) of Example 6 was carried out with the exception of using 39.0 kg of 4-ethyl phenol (Tokyo Chemical Industry Co., Ltd., Japan) instead of 4-phenyl phenol, using 1057 g of urea and carrying out the reaction for 12 hours. When a portion of the reaction liquid was removed and analyzed by liquid chromatography, the formation of (4-ethylphenyl) carbamate was confirmed. The yield was about 88% based on the charged amount of urea.
