标题 :Process for the synthesis of diaminopyridine and related compounds
发明人：RITTER JOACHIM C
权利人:DU PONT; RITTER JOACHIM C
摘要:A process is provided for the synthesis of a diaminopyridine, such as 2,6-diaminopyridine and related compounds, which are used industrially as compounds and as components in the synthesis of a variety of useful materials. The synthesis proceeds by means of a chlorine-ammonia displacement in the presence of a copper source.

标题:Synthesis of semi-crystalline polyphthalamides through reactive extrusion of hexamethylene terephthalamide oligomer with lower melting, semi-crystalline or amorphous polyamides

摘要:This invention relates to the synthesis of semi-crystalline polyphthalamides (i.e. containing monomeric units of terephthalic acid and hexamethylene diamine) through reactive extrusion of hexamethylene terephthalamide oligomer, or the oligomer of another 6T-rich copolymer, with lower melting semi-crystalline or amorphous polyamides. This process is particularly useful since it is centered around the use of stirred autoclaves for the synthesis of the 6T oligomer and the semi-crystalline or amorphous polyamides which are subsequently combined in a twin screw extruder equipped for devolatilization of water of reaction. It can also be used for the modification of existing semi-crystalline or amorphous polyamides (not necessarily phthalamides) with low levels of 6T.
