This utility model discloses a pretreatment device for raw materials in the production of high-purity Kathon, relating to the field of Kathon production technology. The inlet of an ultrasonic reactor is connected via pipelines to a methylchloroisothiazolinone raw material tank and a deionized water tank. The outlet of the ultrasonic reactor is connected via a screw pump to a ceramic membrane device. The liquid phase outlet of the ceramic membrane device is connected via pipelines to a distillation column. The top gas phase outlet of the distillation column is connected via pipelines to a light component tank, an organic solvent tank, and a purified methylchloroisothiazolinone tank. This device achieves effective separation and purification of different components, improving product purity, while simultaneously recovering organic solvents and reducing production costs.

The invention relates to the technical field of preparation of soil conditioners, in particular to an organic complexing agent composition for reducing salt and alkali as well as a preparation method and application of the organic complexing agent composition. The organic complexing agent composition for reducing salt and alkali comprises a pH value regulator and a salt ion and metal ion capturing agent, the salt ion and metal ion capturing agent comprises an outer film layer A and an organic complex component located in the outer film layer A, and the outer film layer A is prepared from polyvinyl alcohol resin; the pH value regulator comprises an outer membrane layer B and a pH value regulating component positioned in the outer membrane layer B; and the outer film layer B is at least one of film-grade polylactic resin or starch composite modified polylactic resin. As a saline-alkali soil conditioner, the saline-alkali soil conditioner provided by the invention can regulate the pH value of soil, effectively remove residual harmful salt ions and heavy metal particles in the soil, and effectively repair the soil and restore the fertility of the soil.
