Technical field
The present invention relates to a kind of
The application of-Lewis bisgallic acid ionic liquid in unsaturated fatty acids methyl esters polyreaction promptly relates to a kind of
The ionic liquid-catalyzed unsaturated fatty acids methyl esters of-Lewis bisgallic acid dimerization prepares the novel method of dimeric acid methyl ester.
Background technology
Dimeric acid methyl ester is the intermolecular generation of two or more unsaturated fatty acid esters Diels-Alder reaction, the oligomeric compound of the dicarboxylic esters that generates, it is actually by 36 carbon dimers, a small amount of 54 carbon tripolymers and the mixture formed of polymer polymer more.Dimeric acid methyl ester can be used to produce polyamide resin, and its snappiness is good, adhesive power is high and antiseptic and rustproof characteristic is arranged, and can be used for making coating, tamanori etc., is widely used in industries such as boats and ships, machinery, motor, automobile, civil construction.The polymkeric substance of dimeric acid methyl ester has good snappiness, sticking power, stopping property and water tolerance, can be used for industries such as electronics, coating, printing ink.Dimeric acid methyl ester and petroleum product, organic solvent have good intermiscibility, thermostability, can be used as metal processing machining oil, lubricating oil, antirust wet goods additive, also can be used as tensio-active agent and be used for washing composition, flow agent, levelling agent, dispersion agent, static inhibitor etc.Bao Dao lipid acid polymerization method is hot dimerization method the earliest, this arts demand high-temperature pressurizing reaction.At present carclazyte catalysis fatty acid methyl ester dimerization reactions that adopt prepare dimeric acid methyl ester more, are catalyzer as US 3873585 with the wilkinite that contains 75% above polynite; It is catalyzer that US 6187903 and US 3632822 adopt the carclazyte of alkali-metal oxyhydroxide and oxide modifying respectively; And CN101293829A employing Aluminum chloride anhydrous or Zinc Chloride Anhydrous are catalyzer, and the vitriol oil is a promotor.There is following shortcoming mostly in these technologies: the consumption of heterogeneous catalyst is excessive, and the meeting entrained product, causes the loss of product; Generally need to carry out under the high pressure, reaction conditions is relatively harsher, and is also higher to the requirement of conversion unit and operation.
Because of having traditional molecular solvent and fused salt dual nature, ionic liquid at room temperature has been widely used in catalysis or the uncatalyzed reaction as eco-friendly green solvent of a class or catalyzer.In recent years, the acid functionalization ionic liquid has become the focus in the research, and its advantage is: compare favourably with solid acid, and the tart modulation is easier, meticulousr, thereby helps the research and the screening of catalyst of catalytic mechanism more; Similar with conventional acid, have the advantage of fluent material, as: good fluidity, acidic site density height and strength of acid are evenly distributed; By changing and modified ion liquid yin, yang ionic structure, can realize the optimization of heterogeneous reaction system, as: simplify the separation of product, promote ion liquid recycling.Therefore, the acid functionalization ionic liquid can replace the conventional acid catalyzer, has great application potential.
Summary of the invention
The objective of the invention is to replace the method that traditional acid catalysis fatty acid methyl polyisocyanate polyaddition prepares dimeric acid methyl ester, a kind of efficient and eco-friendly catalysts is provided, under the reaction conditions of gentleness, catalysis fatty acid methyl ester polyreaction prepares the novel method of dimeric acid methyl ester, for dimeric acid methyl ester synthetic provides an eco-friendly operational path.
The present invention relates to a kind of preparation method of dimeric acid methyl ester, it is characterized in that adopting 1 of the pyridylium of alkylsulphonic acid functionalization or alkylsulphonic acid functionalization, the quaternary ammonium salt cationic of 3-dialkylimidazolium positively charged ion or alkylsulphonic acid functionalization and Lewis tart inorganic anion constitute
-Lewis bisgallic acid ionic liquid is as catalyzer; Reaction conditions is under the nitrogen protection, 200~280 ℃ of temperature of reaction, 2~8 hours reaction times, and catalysis fatty acid methyl ester polyreaction prepares dimeric acid methyl ester.
1 of pyridylium of alkylsulphonic acid functionalization used herein (1) or alkylsulphonic acid functionalization, the general structure of the quaternary ammonium salt cationic (3) of 3-dialkylimidazolium positively charged ion (2) or alkylsulphonic acid functionalization is as follows:

Lewis tart inorganic anion used herein is a kind of in chlorine zincic acid root, bromine zincic acid root, chlorine copper acid group, bromine copper acid group, chlorine ferrous acid root, the bromine ferrous acid root.
Ionic liquid quality used in the present invention is 1: 30 to 1: 4 with the total quality of material ratio of reaction
The present invention solves this technical problem by the following technical programs:
1.
The ion liquid typical production of-Lewis bisgallic acid is: with a certain amount of 1,3-propane sultone or 1, it is in 5~10 times the ethyl acetate that the 4-butane sultone is dissolved in its total mass number, be warming up to 40~60 ℃, drip equimolar N-Methylimidazole, or the N-ethyl imidazol(e), or the N-propyl imidazole, or pyridine, or Trimethylamine 99, or triethylamine, or tripropyl amine, dropwise, after the insulation reaction 3~5 hours, filter, filter cake washs with ethyl acetate, and, obtain corresponding white solid inner salt in 100 ℃ times dry 2 hours; Get a certain amount of inner salt that makes, be dissolved in the deionized water of 2~4 times of its total mass numbers, dripping equimolar mass concentration and be 37% hydrochloric acid or mass concentration is 40% Hydrogen bromide acidification reaction, after dropwising, is warming up to 70~90 ℃ and insulation reaction 2~3 hours; After reaction finished, decompression dehydration obtained light yellow viscous liquid acidifying inner salt; Get a certain amount of acidifying inner salt that makes, with mol ratio be 1: 1.1~3.0 zinc chloride, or zinc bromide, or cupric chloride; or cupric bromide, or iron(ic) chloride, or the iron bromide mixing, under nitrogen protection; be warming up to 90~110 ℃, insulation reaction to solid all dissolves, and promptly obtains being under the room temperature heavy-gravity liquid
-Lewis bisgallic acid ionic liquid.
The typical case of dimeric acid methyl ester preparation be (with
-Lewis bisgallic acid ionic liquid 1-(4-sulfonic acid) butyl-3-Methylimidazole chlorozincate; acidifying inner salt and zinc chloride mol ratio 1: 2.5): get the ionic liquid of 1.0~2.5 parts of weight and the fatty acid methyl ester of 10~30 parts of weight; under nitrogen protection; in 200~280 ℃ of following polyreactions after 2~8 hours; cooling also adds proper amount of solvent toluene extraction product, topples over and tells the upper strata extraction phase.The supernatant liquid solvent that reduces pressure obtains the dimeric acid methyl ester product.
3. the employed ionic liquid of method of the present invention is reusable, ionic liquid multiple canonical process is after the reaction solution extraction with esterification last time, because of under the ionic liquid low temperature very thickness and density greater than extraction phase, can directly topple over easily and the upper strata extraction phase, lower floor's ionic liquid need not any processing and promptly can be used for next polyreaction, when the ionic liquid consumption is reaction solution total mass 20%, to reuse 6 times, the yield of polymerisate dimeric acid methyl ester is not seen obvious decline.
The present invention compares with traditional catalyst, is characterized in:
1. have higher polymerizing power, it is short to need not pressurization and reaction times.
2. product dimeric acid methyl ester look shallow, matter good, and layering voluntarily makes the separation of product and aftertreatment more easy with ionic-liquid catalyst is not miscible.
3. the catalyst ion liquid properties is stable, and reaction is with promptly can be used for reaction next time without any processing later, and catalytic performance do not see reduction, and it is good to recycle performance, genus environmentally friendly technology route.
Specific implementation method
