 butylcarbinol eingerührt, wobei sich das Urethan als weisse krystallinische Masse ausscheidet. Dieselbe wird nach beondigter Reaction von dem überschüssigen Carbinol abgesaugt und bei gewöhnlicher Temperatur getrocknet. Man erhält so das Urethan des Methylbutylcarbinols als weisse   Krystallnadeln   vom Schmelzpunkt 56 . 



   In analoger Weise verfährt. man zur Darstellung der anderen, in der   Hauptanmeldung   genannten Urethane.

 EMI2.1
 butylcarbinol stirred in, the urethane separating out as a white crystalline mass. After the reaction has taken place, the excess carbinol is sucked off and dried at ordinary temperature. The urethane of methylbutylcarbinol is thus obtained as white crystal needles with a melting point of 56.



   Proceed in an analogous manner. to represent the other urethanes mentioned in the main application.

PATENT-ANSPRUCH : Abänderung dos durch das Patent Nr. 4545 geschützten Verfahrens zur Darstellung von Urethanen secundärer aliphatischer Alkohole, darin bestehend, dass man die Chlor- kohlensaureester der betreffenden Alkohole mit Ammoniak behandelt, oder Harnstoffchlorid auf die Alkohole einwirken lässt. PATENT CLAIM: Modification of the process for the preparation of urethanes of secondary aliphatic alcohols, which is protected by patent no. 4545, consists in treating the chlorocarbonic acid esters of the alcohols concerned with ammonia, or allowing urea chloride to act on the alcohols.
