标题 :Method for the synthesis of omega-amino-alkanoic acids
发明人：DUBOIS JEAN-LUC
权利人:DUBOIS JEAN-LUC; ARKEMA FRANCE
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:Process for the synthesis of a copolyester adhesive resin

权利人:GOODYEAR TIRE & RUBBER
摘要:Isophthalic acid is commonly utilized as a comonomer in the preparation of copolyester resins which are utilized as solution adhesives. Unfortunately, solutions of such resins frequently become hazy due to the presence of cyclic oligomers. This invention is based upon the unexpected discovery that the presence of protonic acids during the synthesis of the copolyester resins containing isophthalic acid utilizing conventional metallic catalysts results in solutions of the resins in organic solvents being virtually haze free. The subject invention more specifically reveals a process for synthesizing a polyethylene terephthalate/isophthalate/azelate copolyester resin which is particularly useful as a solution adhesive resin, comprising reacting ethylene glycol with a diacid component which is comprised of (a) from about 25 to about 45 mole percent terephthalic acid, (b) from about 10 to about 30 to about 55 mole percent azelaic acid based upon the diacid component; in the presence of at least one metallic catalyst selected from the group consisting of antimony compounds, titanium compounds; manganese compounds, and germanium compounds and in the presence of at least one protonic acid having a pKa of less than about 2.5; wherein the amount of metallic catalyst present is within the rang eof about 130 ppm to about 1500 ppm and wherein the amount of protonic acid present is within the range of about 50 ppm to about 500 ppm, with said amounts being based upon the weight of the copolyester resin produced.

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.
