Abstract
本发明涉及一种松香及其衍生物酯化的新方法。The invention relates to a new method for esterification of rosin and its derivatives.
松香性脆，易氧化，酸值较高，热稳定性差，妨碍了它的应用。松香酯化改性是利用松香资源的最大途径，松香酯化后，克服了上述缺点中的绝大部分，并拓宽其应用领域。目前普遍采用的松香及其衍生物的酯化催化剂存在着催化活性不高、反应时间长、能耗高等缺点。Rosin is brittle, easy to oxidize, has high acid value and poor thermal stability, which hinders its application. Rosin esterification modification is the biggest way to utilize rosin resources. After rosin esterification, most of the above-mentioned shortcomings are overcome, and its application field is broadened. The currently widely used esterification catalysts of rosin and its derivatives have disadvantages such as low catalytic activity, long reaction time, and high energy consumption.
本发明提供一类高效的松香树脂酸酯化催化剂，均为原子序数在57～71之间的三价稀土金属氧化物，尤其是Nd2O3，Sm2O3，Gd2O3，La2O3等。它们催化松香酯化时，仅需松香或其衍生物重量的0.08%～2%，反应时间也大大缩短，反应温度亦有降低；酯化产品均匀透明、色泽浅。为松香及其衍生物的酯化改性工艺更好的适合现代化工生产提供了新途径。The invention provides a class of high-efficiency rosin resin esterification catalysts, all of which are trivalent rare earth metal oxides with atomic numbers between 57 and 71, especially Nd 2 O 3 , Sm 2 O 3 , Gd 2 O 3 , La 2 O 3 etc. When they catalyze the esterification of rosin, only 0.08% to 2% of the weight of rosin or its derivatives is needed, the reaction time is greatly shortened, and the reaction temperature is also lowered; the esterification product is uniform, transparent, and light in color. It provides a new way for the esterification modification process of rosin and its derivatives to be better suitable for modern chemical production.
Description
The present invention relates to the novel method of a kind of rosin and esterification of derivatives thereof.
Rosin is the first afforestation product resource of China, as a kind of natural resin of excellent property, has obtained using widely.But rosin is crisp, easy oxidation discoloration, has hindered its application to a certain extent.Esterification modification is to widen one of most important means of fundamental sum of rosin application approach.After the rosin esterification modification, performance is improved greatly.Various rosin (comprising nilox resin and staybelite) ester accounts for more than 60% of Abietyl modified product, and its polyol ester is widely used in industries such as coating, printing ink, rubber, tackiness agent as tackifier; The monobasic alcohol ester also can be used as rubber and plastic processing additives.
The rosin that generally adopts and the esterifying catalyst of derivative thereof have bronsted acid catalyst now, as sulfuric acid, Hypophosporous Acid, 50 etc.; Solid acid catalyst such as zinc oxide.The esterification reaction tech of these catalyst rosin and derivative thereof need high temperature (250～300 ℃) and long-time (7～11h) (" modern chemical industry ", 1994,2, p43), energy consumption of reaction is big, by product is many, as follows easily produces PH during phosphoric acid catalyzed
3Deng toxic gas contaminate environment (US.4690783); Sulfuric acid then easily makes the rosin decarboxylation and reaction vessel is had corrosive nature (US.4172070).The catalytic reaction of protonic acid generally needs in the alkali and aftertreatment (US.4650607) such as grade.
The objective of the invention is for the rosin esterification modified industry provides sharp novel, a highly active catalyzer, rosin and derivatives catalysis esterification thereof are synthesized their ester compound; Its polyol ester is the tackifier of macromolecular material, and the monobasic alcohol ester is the softening agent of macromolecular material.
Rosin esterification catalyzer provided by the present invention, rare-earth oxide is compared with traditional protonic acid, solid acid catalyst, and it is few to have a catalyst levels, the short and low characteristics of temperature of reaction of reaction times; Esterified prod homogeneous transparent, lighter color.From the industrial application angle, unfavorable factors such as such catalyzer has been eliminated traditional protonic acid, the solid acid catalyst activity is not high, side reaction is many, long reaction time, energy consumption height, contaminate environment, thus make the esterification modification process of rosin and derivative thereof can better be fit to the needs of modern chemical industry production development.
The enforcement of rosin and esterification of derivatives method thereof comprises following process: add catalyzer around the rare-earth oxide account for reactant weight 0.08～1.2% (the best is 0.4～1.2%) in rosin or derivatives thereof and the pure reaction system, 200～260 ℃ of temperature of reaction, 2～6 hours reaction times: boil off the ester compound that remaining alcohol and solvent can obtain the rosin or derivatives thereof.Rosin derivative mainly is to contain carboxy derivatives in the reaction system, and reactant alcohols carbonatoms is 1～18 (the best is 2～12 carbon atoms), comprises monohydroxy-alcohol, dibasic alcohol, trivalent alcohol or the tetravalent alcohol etc. of Fatty Alcohol(C12-C14 and C12-C18) and aromatic alcohol.Catalyzer rare earth metal oxide compound is the trivalent rare earth metals oxide compound of ordination number between 57～71, for example Nd
