Abstract
A process to make the ester with the rosin and the acrylate includes: first the rosin is dissolved in the benzol and react with the acyl reagent for 3h under 50DEG C to change the carboxyl into the acyl chloride; second the rosin acyl chloride react with the acrylate for 3h under 50DEG C to get the rosin ester. The percent conversion of the acrylate can reach above 90%, the reactive byproduct is also the important chemical material; the rosin ester has the good polymeric activeness, so it can be used for composing the high molecular polymer to improve the heat and chemical resistance.
Description
Technical field
The present invention relates to a kind of method of producing ester by rosin and acrylate.
Technical background
Rosin has many excellent characteristic, as anticorrosion, moistureproof, insulation, bonding, emulsification, softening etc.Before 1700 in the Shennong's Herbal with rosin as drug use.According to statistics, the rosin purposes has kind more than 400.Since the nearly century, rosin and deep processing modified product thereof are widely used in many fields such as coating, tackiness agent, printing ink, papermaking, rubber, foodstuff additive and biological products.The rosiny chemistry utilizes by directly utilizing rosin mixture primary products to utilize the special-purpose tandem product direction of the pure product exploitation of rosin derivative to develop to the degree of depth.The Abietyl modified application performance that not only can improve product, the while also can be improved the added value of rosin resource, is devoted to rosin chemical modification utilization research both at home and abroad always.
Ternary phenanthrene ring structure in the rosin molecular skeleton has certain rigid, if can be incorporated into resistance toheat and the chemical resistance that removes to improve effectively polymkeric substance in the polymer to it.Acrylic ester polymer is a kind of range of application polymkeric substance very widely, as organic glass (polymethylmethacrylate), Pressure sensitive adhesive tape (multipolymer of butyl acrylate-Isooctyl acrylate monomer-methyl methacrylate).Rosin is applied in the acrylic ester polymer as tackifying resin usually and goes, but this only is a kind of mechanical blending, and the two fails to realize chemical bonding, As time goes on, it is bad that the performance of blend can become, and this blend and underuse characteristics on the rosin molecular structure.If can might successfully be implemented in the purpose of introducing rosin ternary phenanthrene ring structure on the macromolecular chain connecting polymerisable group by the chemical bonding effect on the rosin molecular skeleton.
Rosin is the mixture of a series of resinous acids, and comprise main the composition such as pimaric acid, isopimaric acid, palustric acid, abietic acid, neoabietic acid, dehydroabietic acid etc.They all contain two keys (conjugation or non-conjugated) of a ternary phenanthrene ring frame, carboxyl side group and different loci and quantity.Rosin has multiple common derivative on the basis of not destroying the rosin molecular skeleton, as staybelite, nilox resin, maleated rosin, acrylic acid rosin etc.
Carboxyl in the rosin acid, the same with other monocarboxylic acid, can generate corresponding ester class with multiple alcohols reaction.But because carboxyl is positioned on the tertiary carbon atom, have bigger sterically hinderedly, making it esterification needs higher or than the reaction conditions that causes that generally esterification is more fierce.The principal item of rosin ester is rosin monobasic alcohol ester, rosin binary alcohol esters, rosin triol ester and rosin quaternary alcohol ester.Their synthetic method is in the rosin fusion and has under the condition of catalyzer, generates corresponding rosin ester class with alcohols (more than 250 ℃) direct esterification at high temperature.Esterification of rosin esterification is a balanced reaction, need improve temperature of reaction and vacuumize the water of removing the reaction generation in the reaction later stage and carry out to impel reaction forward.
Because acrylate is thermopolymerization easily at high temperature, so this patent can not adopt above-mentioned enzymatic synthesis condition.
When adopting elder generation that rosin is carried out this gentle relatively reaction conditions of chloride resterification, can avoid the auto-polymerization of acrylate and the generation of other unfavorable side reaction.
Rosin, staybelite, nilox resin, maleated rosin and acylting agent are carried out acyl chloride reaction; generate chloride compounds; again with the esters of acrylic acid reaction that contains hydroxyl; on the rosin molecular skeleton, introduce acrylate group, just can contain the macromole of ternary phenanthrene ring (rosin group) structure with a series of incompatible preparation of compound copolymerization that contains two keys.
Summary of the invention
The invention provides a kind of thermopolymerization that can avoid acrylate, simple to operate and cheap for manufacturing cost produce the method for ester by rosin and acrylate, the polymkeric substance that the ester copolymerization that is made by the present invention forms has the advantage of good heat resistance.
The present invention adopts following technical scheme:
The first step: the rosiny acyl chloride reaction is dissolved in the rosin of 100 parts of quality in the benzene solvent of 10-500 part quality, the acylting agent of 1-70 part quality is dissolved in the benzene solvent of 1-70 part quality, the acylting agent drips of solution is added to mixing and stirring in the rosin solution, reaction times 1-6 hour, temperature of reaction maintains between 30 ℃-80 ℃, this reaction makes the carboxyl in the rosin be converted into acid chloride groups, above-mentioned solution is filtered to remove impurity, benzene solvent is reclaimed in underpressure distillation (vacuum tightness is that 0.1MPa, solution temperature are 80 ℃), makes the rosin acyl chlorides thus;
Second step: the rosin acyl chlorides of 100 parts of quality that the esterification of rosin acyl chlorides will make is dissolved in the benzene solvent of 10-500 part quality, the acrylate that contains hydroxyl of 1-60 part quality is added drop-wise to mixes in the rosin solution of acid chloride and stir; Reaction times 1-6 hour, temperature of reaction maintained between 30 ℃-80 ℃, and this reaction makes acyl chlorides and hydroxyl reaction generate ester group, and benzene solvent is reclaimed in underpressure distillation (vacuum tightness is that 0.1MPa, solution temperature are 80 ℃), prepares rosin (acrylate) ester thus.

Elder generation joins 40g maleated rosin acyl chlorides in the 100g benzene, after treating fully to dissolve, drips 12.03g methacrylic acid-3-hydroxy-propyl ester and mixes and stirring to the maleated rosin solution of acid chloride, and the reaction times is 3 hours, and temperature of reaction maintains 60 ℃.After reaction finished, benzene solvent was removed in underpressure distillation (vacuum tightness is that 0.1MPa, solution temperature are 80 ℃), prepares maleated rosin (methacrylic acid-3-hydroxy-propyl ester) ester thus.The variation of group infrared absorption is analyzed in sampling half an hour at interval in the reaction process with the infrared spectra tracking monitor.
Proportioning:
A maleated rosin acyl chlorides 40 grams
B methacrylic acid-3-hydroxypropyl acrylate 12.03 grams
Products therefrom is maleated rosin (methacrylic acid-3-hydroxy-propyl ester) ester, and yield is 93%.
Claims (5)
1. produce the method for ester by rosin and acrylate for one kind, it is characterized in that may further comprise the steps:
