Abstract

The invention discloses a solvent-free preparation method for polyamides. According to the method, glycol reacts with diamine in the presence of a ruthenium catalyst with a concentration of 0.01 mol% to 5 mol%; the reaction is carried out at a temperature in a range of 130 DEG C to 300 DEG C, and a variety of aliphatic polyamides and non-aliphatic polyamides are obtained.

Description

The method of being prepared polymeric amide by glycol and diamines
Technical field
The present invention relates to by direct coupling glycol and diamines, prepare the no-solvent process of polymeric amide under the existence of ruthenium catalyst.
Background technology
Polymeric amide is normally prepared as the condensation reaction of acyl chlorides by diamines and diacid or two acid precursor.The business synthetic method of fatty polyamide generally includes following two steps: (1) is at room temperature first used in the diacid of 1:1 molar ratio and diamines and formed acid/alkali salt; (2) more described salt be heated to certain high temperature (for example, for polyamide 6,6 is 285 ° of C) and/or under high pressure by melt condensation, form polymeric amide.The main drawback of this class polycondensation method is harsh condition and/or produces Toxic waste (for example HCl).
In addition, polymeric amide also can be prepared by the ring-opening polymerization of lactan or N-carboxyamino acid anhydrides.For example, polyamide 6 is to commercially produce by ring-opening polymerization method.Yet, for the preparation of the cyclic monomer of ring-opening polymerization method, be still confined to harsh reaction conditions.
Recently, the people such as Milstein disclose and have used ruthenium catalyst to make alkohol and amine react to prepare the direct dehydrogenation amidation method of various acid amides in US2009/0112005A1, and molecular hydrogen is the unique by product in this reaction.With regard to high yield and high conversion and minimum by product generation aspect, this catalysis amidation method very advantageous.
The people such as Guan are at JACS (2011) 133, have reported that utilizing ruthenium catalyst catalytic dehydrogenation amidation method to prepare some main chain contains heteroatomic functionalized poly acid amides in the 1159th page.Described dehydrogenation polyamidation method is utilized the Ru catalyzer of 1 % by mole conventionally, by this Ru catalyzer and glycol and diamines at solvent system (for example, phenylmethylether, or phenylmethylether/DMSO (4:1) mixture) middle pre-mixing, then 120 ° of C heating 48 hours.By carefully selecting to be applicable to the glycol of heteroatoms replacement and/or the solvent system of diamines, dehydrogenation polyamidation method provides the functionalized poly acid amides of number-average molecular weight (Mn) within the scope of 10 to 30KDa.
Yet conventionally known fatty polyamide is as polyamide 6,6 and polymeric amide 10, the 10 optimum reaction condition preparation that can not use the people such as Guan to report, reason is that fatty polyamide only has low solubility in reported solvent system.In addition, the high catalyst load of 1 % by mole with respect to reactant has also improved the cost that carries out commercial production by dehydrogenation polyamidation method.
In view of fatty polyamide widespread use for parts and housing in automobile, Electrical and Electronic and textile industry, people expect that a kind of dehydrogenation polyamidation method of improvement can be used in synthetic fat family/aromatic polyamide.
The applicant finds beyond the consideration " solvent-free " in the situation that, under the existence of ruthenium catalyst, direct coupling glycol and diamines can be prepared fatty polyamide, polyamide 6 for example, 6 and polymeric amide 10,10 and non-fatty polyamide such as polyamide 6 T, polymeric amide 10T etc.Therefore, the invention provides new eco-friendly " solvent-free " dehydrogenation polyamidation method of preparing fatty polyamide, non-fatty polyamide and other functionalized poly acid amides.
