Embodiment 1

[0017] Dissolve 100 grams of rosin in 100 grams of toluene solvent, add 20 grams of glycidyl methacrylate, stir and mix evenly, then add 0.2 grams of catalyst triethylamine and 0.1 grams of polymerization inhibitor hydroquinone, and heat to 100 ° C for reaction After 5 hours, after the reaction, the temperature was lowered to 70° C., and the solvent toluene was recovered by distillation under reduced pressure at a vacuum degree of 0.1 MP. The obtained product was an esterified product prepared from rosin and glycidyl methacrylate.

Embodiment 2

[0019] Dissolve 100 grams of rosin in 200 grams of toluene solvent, add 80 grams of glycidyl methacrylate, stir and mix evenly, then add 2 grams of catalyst triethylamine and 0.5 grams of polymerization inhibitor hydroquinone, and heat to 80 ° C for reaction After 8 hours, after the reaction, the temperature was lowered to 70° C., and the solvent toluene was recovered by distillation under reduced pressure at a vacuum degree of 0.1 MP. The obtained product was an esterified product prepared by using rosin and glycidyl methacrylate.

Embodiment 3

[0021] Dissolve 100 grams of rosin in 300 grams of toluene solvent, add 100 grams of glycidyl methacrylate, stir and mix evenly, then add 3 grams of catalyst triethylamine and 1 gram of polymerization inhibitor hydroquinone, and heat to 60 ° C for reaction After 10 hours, after the reaction, the temperature was lowered to 70° C., and the solvent toluene was recovered by distillation under reduced pressure at a vacuum degree of 0.1 MP. The obtained product was an esterified product prepared by using rosin and glycidyl methacrylate.

Abstract

The invention discloses a method for preparing an ester compound by colophony and glycidyl methacrylate. The method comprises the following steps of: dissolving 10 parts by weight of colophony in 10-300 parts by weight of toluene solvent, adding 20-100 parts by weight of glycidyl methacrylate, evenly mixing in a stirring way, adding 0.2-3 parts by weight of catalyst triethylamine and 0.1-1 part by weight of polymerization inhibitor hydroquinone, heating to lead the reaction temperature to keep at 60-100 DEG C, reacting for 5-10h, and after ending the reaction, and distilling by means of pressure reduction under the temperature of 70DEG C and the vacuum degree of 0.1MP to recover solvent toluene, so that the obtained product is the ester compound prepared by colophony and the lycidyl methacrylate. The preparation method has the advantages that the raw material is easy to take, the one-step method is simple in reaction operation, reaction temperature is low, the energy consumption can be saved, the solvent is easy to recover and the like; and the obtained product contains an acryloxy functional group, is high in polymerization activity, and can be co-polymerized with other monomers, so that a ternary phenanthrene ring-containing polymer can be prepared.

Description

technical field [0001] The technical field of the invention belongs to the field of chemical synthesis and chemical production, in particular to a method for preparing esterified products by utilizing rosin and glycidyl methacrylate. Background technique [0002] Rosin has many excellent physical and chemical properties, such as anti-corrosion, insulation, adhesion, emulsification, etc. Rosin products are widely used in coatings, adhesives, inks, paper, rubber, food, biological products and other fields. Rosin has developed from the direct use of primary products to the deep use of rosin derivatives. The high acid value of rosin limits its wider application. Through modification, the application performance of the product can be improved, and the added value of the rosin itself can be increased. [0003] The esterification of rosin is one of the main modified products of rosin. With the development of the national economy, people put forward higher requirements on the qu...
