Embodiment 1

[0047] In a 4000L enamel reaction kettle, add 620Kg rosin and 2200Kg toluene, stir to dissolve the rosin completely, then add the uniform suspension containing 125Kg copper sulfate pentahydrate, 160Kg sodium hydroxide and 400Kg water dropwise to the rosin solution within 30 minutes During the process, the color of the reaction solution gradually turns green. After the addition is completed, the temperature is raised to reflux temperature for dehydration reaction. After the dehydration is completed, the reaction solution is cooled, and impurities are filtered out to obtain a toluene solution of copper rosinate with a detection content of 38%.

Embodiment 2

[0049]In a 2000L enamel reaction kettle, add 300Kg rosin and 1000Kg cyclohexanone, stir to dissolve the rosin completely, and then add a uniform suspension containing 60Kg copper chloride, 168Kg potassium hydroxide, and 200Kg water dropwise to the rosin within 30 minutes. In the solution, the color of the reaction solution gradually turns green. After the dropwise addition, the temperature is raised to the reflux temperature for dehydration reaction. After the dehydration is completed, the reaction solution is cooled, and then the impurities are filtered out to obtain a cyclohexanone solution of copper rosinate with a detection content of 33 %.

Embodiment 3

[0051] In a 1000L enamel reaction kettle, add 160Kg rosin and 480Kg n-butanol, stir to dissolve the rosin completely, and then drop the uniform suspension containing 40Kg copper citrate, 25Kg ammonia water, and 80Kg water into the rosin solution within 30 minutes , the color of the reaction solution gradually turns green, after the dropwise addition is completed, the temperature is raised to the reflux temperature, and the dehydration reaction is performed. After the dehydration is completed, the reaction solution is cooled, and then the impurities are filtered out to obtain a n-butanol solution of copper rosinate, with a detection content of 45%.

Abstract

The invention discloses a preparation method and application of gum rosin acid copper. The method for preparing the gum rosin acid copper comprises the following steeps: evenly mixing copper salt with alkali liquor; mixing the obtained mixture into a uniform suspension; then slowly dropping the uniform suspension into a solution consisting of rosin and solvent, wherein in the dropping process, the color of the solution is gradually changed from blue to green, and the exothermic phenomenon is produced, then timely cooling is carried out in time, and the dropping process is completed within 20 to 40 minutes; after the dropping process is completed, raising the temperature of the obtained solution to 70 to 90 DEG C, and then carrying out atmospheric dehydration reaction on the obtained solution by using a water separator (100L); and after the dehydration reaction is completed, filtering the obtained object by using standard filter papers so as to obtain a gum rosin acid copper solution of which the concentration is 20 to 50 percent, then analyzing and detecting the content of the obtained product. The application of the gum rosin acid copper is as follows: the gum rosin acid copper prepared in the invention is used together with medicaments for preventing crop diseases and pests. The invention solves the problems that the existing method for preparing the gum rosin acid copper is complicated, hard to implement and not environmental-friendly, and the application scope of the current gum rosin acid copper is narrow.
