标题:Synthesis of semi-crystalline polyphthalamides through reactive extrusion of hexamethylene terephthalamide oligomer with lower melting, semi-crystalline or amorphous polyamides
发明人：LEBOEUF CHRISTIAN; HARBOURNE DAVID ALAN
权利人:LEBOEUF CHRISTIAN; HARBOURNE DAVID ALAN
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.

摘要:The invention relates to a method for the synthesis of amino acids/esters of general formula NH 2 —(CH 2 ) n —COOR in which n is an integer between 5 and 14, and R is either H or an alkyl radical including from 1 to 4 carbon atoms, from natural long-chain mono-unsaturated fatty acids or esters including at least 10 adjacent carbon atoms per molecule, said method comprising: first converting, if necessary, said natural long-chain fatty acid or ester into a monounsaturated fatty acid/ester of general formula R 1 —(CH 2 ) m —CHâ•?CH—(CH 2 ) p —COOR in which R 1 is H, CH 3 or a COOR radical, m is an integer between 0 and 14 and p is an integer between 2 and 11, then submitting the latter to a crossed catalytic metathesis reaction with a compound of formula R 2 —CHâ•?CH—R 3 in which R 2 is either H or CN and R 3 is CN or CH 2 NH 2 , provided that if R 2 is CN, R 3 can be only CN, and finally converting the resulting product of the general formula R 3 —CHâ•?CH—(CH 2 ) p —COOR into an amino-acid, either by hydrogenation, or by hydrogenation of the trple terminal bond, or by amination of the double terminal bond.

标 题:Device for the synthesis of a polymer with extraction of a gaseous substance comprising a reaction chamber having at least one circular-cylindrical section
发明人：ZHU NING; STAMMER ACHIM; CLAUSS JOACHIM; KORY GAD
权利人:BASF SE
摘要:An apparatus for synthesis of a polymer with separation of a gaseous substance comprises a reaction space having an essentially circular cylindrical upper section which is bounded by two circular faces and one shell face and has a longitudinal cylinder axis, and a lower section, an inlet orifice disposed in a circular face or the shell face of the upper section, a first outlet orifice disposed in a wall of the lower section, a second outlet orifice disposed in the shell face of the upper section opposite the first outlet orifice, and a removal device which is disposed so as to be rotatable about the longitudinal cylinder axis and is in contact with both circular faces and the shell face. This apparatus can especially be used for performance of a process including the feeding of an oligomer melt into a reaction space through an inlet orifice, the polymerization of the oligomer melt to give a polymer melt, the removal of the polymer melt from the reaction space through a first outlet orifice of the reaction space, and the removal of a gaseous substance from the reaction space through a second outlet orifice of the reaction space, wherein deposits on at least one inner wall of the reaction space are removed by a removal device and transported into the oligomer melt.
