Description
<EMI ID=1.1>
L'invention concerne un procédé pour la préparation de
<EMI ID=2.1>
<EMI ID=3.1>
<EMI ID=4.1>
grand que 5.
<EMI ID=5.1> <EMI ID=6.1> <EMI ID=7.1> <EMI ID=8.1>
en refroidissant convenablement. Pendant la réaction, on peut encore ajouter un peu i'aloali, pour rendre celle-ci oomplète.
