I have begun to look at the patents again. Patents 4,937,383 and 4,827,031 look good.
HOWEVER, I still am wary about the isomerization, but they look easy to test. # 4,827,031 doesn't look as promising, the pressures are higher, it quotes use for compounds 2-8 carbons long, and uses slightly higher temperatures.
# 4,937,383 looks more promising. The pressures seem attainable. The yields are well below 50% though.
US Patents # 5,107,027 and # 5,900,508 seem not too good. The zeolites, if you can get them, are pretty acidic and might cause ether cleavage and will cause some polyermization. The patents do state however that they can aminate compounds 2-10 carbons long, even with aryl groups. The patent DO NOT tell you weather the addition id Markinokovian though, which is of great importance. If anyone can figure that out please post it...
