Abstract

The invention discloses a method for recycling lambda-cyhalothric acid from lambda-cyhalothric acid residual liquid. According to the technical scheme, the method comprises the following preparation steps that S1, the recycled lambda-cyhalothric acid residual liquid is placed into a storage tank in a centralized mode; S2, the lambda-cyhalothric acid residual liquid in the storage tank is filtered;S3, the filtered lambda-cyhalothric acid residual liquid is poured into a reaction kettle; S4, water is added into the reaction kettle; S5, a stirring device is inserted to thereaction kettle, and stirring and cleaning are carried out; S6, secondary filtration on the stirred lambda-cyhalothric acid residual liquid is carried out; S7, the filtered lambda-cyhalothric acid residual liquid is pouredinto a heating device and constant-temperature heating is carried out; S8, sodium hydroxide is added into the catalyzed lambda-cyhalothric acid residual liquid; and S9, the target product lambda-cyhalothric acid is obtained by saponification of the lambda-cyhalothric acid residual liquid. Thestorage tank in the S1 is made of glass. The method has the beneficial effects that recycling is achieved,the filterability is high, and the insecticidal effect of extracted lambda-cyhalothric acid is remarkable.

Description

technical field [0001] The invention relates to the field of kung fu chrysanthemic acid, in particular to a method for recovering kung fu chrysanthemic acid from kung fu chrysanthemic acid residue. Background technique [0002] Kung fu chrysanthemic acid is a yellow to brown viscous oily liquid, stable under light, and is a pyrethroid insecticide, which can effectively control various pests on cotton, fruit trees, vegetables, soybeans and other crops, and can also control insects on animals. of parasites. [0003] Used to control pests on cotton, vegetables, tobacco and other crops; high-efficiency, broad-spectrum, quick-acting pyrethroid insecticides, acaricides, mainly contact and stomach toxicity, no systemic effect, can effectively control A variety of pests on cotton, fruit trees, vegetables, soybeans and other crops can also prevent and control parasites on animals. , gall mites, tarsal line mites, etc. have good effects, and can be used to control cotton bollworms a...
