[0028] A kind of copper rosinate raw drug preparation method is characterized in that, comprises the following steps:

[0029] 1) Weigh 10-80 parts by weight of rosin, 2-50 parts by weight of organic solvent, and 1-40 parts by weight of organic acid, mix them evenly, add them into a reaction kettle with a vacuum reflux device, start the reflux device, and set the temperature at 50-80°C. Heat and stir to dissolve the rosin completely;

[0030] 2) Add 1-40 parts by weight of inorganic copper, add 0.01-0.5 parts by weight of catalyst, heat and stir, and carry out catalytic reaction at 120°C-170°C, and the reaction time is 4-5 hours;

[0031] 3) After the condensate is completely recovered, the material is discharged;

[0032] 4) cooling to obtain the former medicine of massive copper rosinate.

[0033] Wherein the above-mentioned parts by weight correspond to the kilograms in the examples.

Abstract

The invention relates to a copper abietate raw drug and a preparation method thereof; the copper abietate raw drug comprises the following components in parts by weight: 10-80 parts of rosin, 1-40 parts of inorganic copper, 1-40 parts of an organic acid, 2-50 parts of an organic solvent, and 0.01-0.5 part of a catalyst. The preparation method comprises the steps: mixing evenly 10-80 parts by weight of the rosin, 2-50 parts by weight of the organic solvent and 1-40 parts by weight of the organic acid, adding into a sealed reaction kettle with a vacuum reflux unit, heating and stirring, after the rosin is completely dissolved, adding 1-40 parts by weight of inorganic copper, then adding 0.01-0.5 part by weight of the catalyst, heating up and carrying out a refluxing reaction, recycling a reflux condensed fluid, discharging, and cooling to obtain the copper abietate raw drug. The copper abietate raw drug obtained by adopting the copper abietate raw drug synthesis formula and the preparation method has the advantages of being high in content, suitable for preparation of a variety of forms of copper abietate bactericide products and the like.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a copper rosinate raw drug, a preparation method and an application. Background technique [0002] Copper preparation fungicide has the characteristics of the earliest development and application time, the longest use time, the largest application area, good bactericidal effect and wide application. This kind of fungicide can prevent and treat fungal diseases as well as bacterial diseases; it has both protective and preventive effects, and has certain therapeutic and eradicating effects; it can be used not only for wound healing, but also for sterilization and anti-inflammation . Mainly divided into inorganic copper fungicides and organic copper fungicides. However, there is a problem that cannot be ignored in the long-term continuous use of inorganic copper fungicides, that is, it is easy to induce the proliferation of mites and cause the damage of mites. According to many years of ...
