Reaction Steps

The same method as step (6-1) of Example 6 was carried out with the exception of using 8040 g of p-heptyl phenol instead of 4-phenyl phenol, using 378 g of urea and carrying out the reaction for 16 hours. When a portion of the reaction liquid was removed and analyzed by liquid chromatography, the formation of (p-pentylphenyl) carbamate was confirmed. The yield was about 90% based on the charged amount of urea.
