| titleOfInvention | A kind of processing method of abamectin ointment |
| abstract | The present invention provides a kind of processing methods of abamectin ointment, comprising the following steps: halogenated hydrocarbon solvent a, is added into abamectin ointment, stirring and dissolving abamectin ointment under the conditions of 30 DEG C ~ 70 DEG C obtains uniform solution；B, above-mentioned solution is cooled to 5 DEG C ~ 0 DEG C, dissolved agent is added, stirring continues 1 ~ 2h of stirring after crystalline substance out, obtains magma；The dissolved agent is the agent of alkanes dissolved；C, at normal temperature, gained magma is filtered or is centrifugated, obtains avermectin effective component powder.The present invention is extracted the effective component B1a almost all in abamectin ointment by the method for dilution crystallization, yield is up to 96%, abamectin ointment is set to become pulvis shape from the ointment shape of original difficult, difficult storage simultaneously, solve the problems, such as that abamectin ointment is difficult to store, abamectin ointment is avoided caused by environment and crops or the harm that may cause, also the preparation of the toxic solvents such as toluene, which need not be reused, can sell ointment, more safety and environmental protection. |
