Description
Verfahren zur Herstellung eines N-substituierten cyclischen Amidins. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines N-substi- tuierten c yclischen Amidins, welches dadurch gekennzeichnet ist, dass man '-Nlelamin mit, Oetodecylamin im lIolel@ularverhältnis 1:
2 urnetzt, wobei die eine der beiden Kompo nenten als mineralsaures Salz zur Verwen- duilg kommt.
Das so erhaltene, bisher noch nicht bekannte N,N'-Distearylmelamin ist ein farbloses, kri stallines Pulver vom Schmelzpunkt 7 2 bis <B>75'</B> C und soll zur Herstellung von harz artigen Kondensationsprodukten Verwendung finden.
Beispaiel: 1ss Gewichtsteile Melamin und 61 Ge- tviehtste',le Octodecylaminclilorhydrat (Mo- lelkalarvei-hältnis <B>1:</B> ?) werden vermahlen und etwa vier Stunden auf etwa 200 bis 210' C erh',zt. Die Schmelze wird zerkleinert, mit wässeriäem Ammoniak verrührt, abgesaugt und mit Wasser gewaschen. Sodann kocht man mit Alkohol aus, filtriert von unverän dertem 1VIelamin ab und kühlt das Filtrat ab.
Man erhält daraus das N,N'-Distearylmelamin in guter Ausbeute.
Process for the preparation of an N-substituted cyclic amidine. The present patent relates to a process for the preparation of an N-substituted cyclic amidine, which is characterized in that '-Nlelamine is mixed with, oetodecylamine in a lolel @ ular ratio of 1:
2 urnetz, whereby one of the two components is used as a mineral acid salt.
The previously unknown N, N'-distearylmelamine obtained in this way is a colorless, crystalline powder with a melting point of 72 to 75 ° C and is intended to be used for the production of resinous condensation products.
Example: 1ss parts by weight of melamine and 61 weighted portions of octodecylamine chlorohydrate (molel kalarvei ratio <B> 1: </B>?) Are ground and raised to about 200 to 210 ° C for about four hours, partly. The melt is comminuted, stirred with aqueous ammonia, filtered off with suction and washed with water. It is then boiled with alcohol, unaltered 1VIelamin is filtered off and the filtrate is cooled.
The N, N'-distearylmelamine is obtained therefrom in good yield.
