13synthesis methods

Product Name:Benzyl carbamate
CAS Number:621-84-1
Molecular formula:C8H9NO2
Molecular Weight:151.16

Benzyl carbamate is prepared by reacting benzyl chloroformate with ammonia. Benzyl chloroformate was slowly added to 5 times the volume of cold ammonia water (relative density 0.90) under vigorous stirring, the reaction mixture was placed at room temperature for 30 minutes, the precipitate was filtered out, washed with water and dried to obtain the finished product of benzyl carbamate.

Reaction Conditions:

with alumina supported nickel oxide-bismuth oxide oxide catalyst at 110; for 10 h;Sealed tube;

Steps:

4.B B. Preparation of benzyl carbamate
540g of urea, 3000mL of benzyl alcohol and 5.4 catalyst C were introduced into a 10L reaction kettle in sequence, sealed, heated to 110°C and reacted at this temperature for 10 hours to obtain benzyl carbamate.After testing, the yield of benzyl carbamate was 99.00%, and no benzyl carbamate was detected in the benzyl carbamate (exceeding the detection limit of 0.00001%).
