The application provides a hybridoma cell strain secreting monoclone antibody of diquat and application thereof, and relates to the technical field of immune detection. The monoclone antibody secreted by the hybridoma cell strain has good sensitivity to diquat, the IC 50 1.13 ng / mL, so that the monoclone antibody can detect trace diquat. In addition, the monoclone antibody has no cross reaction to structural analogs of diquat, such as alachlor, acetochlor, butachlor, propanil, diquat and diquat, so that the monoclone antibody can accurately detect low concentration diquat.

The invention belongs to the technical field of mineral processing, and particularly relates to an octylphenoxyacetic acid compound as well as a preparation method and application thereof. The chemical structure of the octylphenoxyacetic acid compound provided by the invention contains ether groups, and the octylphenoxyacetic acid compound has stable low-temperature flotation performance, has the advantages of strong collecting capacity and good selectivity, and can obtain good beneficiation indexes when being used for oxidized ore flotation. When being matched with the fatty acid saponified matter and the oxidized paraffin soap for use, the high-efficiency collecting agent can also achieve the excellent effects of lower dosage and better collecting performance.

The invention discloses a synthetic method of sec-octyl phenoxyacetic acid, and relates to the technical field of organic synthesis and green chemistry. According to the synthesis method provided by the invention, phenol and sec-octanol are used as raw materials, and a one-pot method is adopted and comprises the following steps: a, putting phenol, sec-octanol, an etherification reagent, an ionic liquid catalyst, an etherification catalyst and an ionic liquid reaction medium into the same reactor, and sequentially carrying out an alkylation reaction and an etherification reaction at a certain temperature, the sec-octyl phenoxy acetic acid is obtained; and b, after the reaction is finished, cooling and filtering a reaction system, adding deionized water into filtrate for separation, collecting an organic phase, and carrying out recrystallization treatment to obtain the high-purity sec-octyl phenoxy acetic acid. According to the synthesis method disclosed by the invention, two reactions of alkylation and etherification are efficiently carried out in a compatible system, the total yield is far higher than that of a traditional method, the used catalyst and solvent can be recycled, and the whole technological process is basically free of acidic wastewater or salt-containing organic wastewater which is difficult to treat and is environment-friendly.

The invention discloses penicillin G acylase for synthesizing penicillin V and a mutant of the penicillin G acylase, which can catalyze a reaction of a substrate 6-APA and phenoxyacetate to generate the penicillin V, and provides a new way for enzymatic synthesis of the penicillin V.

The utility model discloses lopinavir intermediate 2, 6-dimethyl phenoxy acetic acid waste liquid and waste residue treatment equipment, which belongs to the technical field of chemical equipment and comprises a rack, a filtering unit, a driving mechanism and a separating unit. Wherein the liquid flows downwards to a filter box to be guided, discharged and collected, at the moment, a driving motor drives a scraping mechanism to conduct circumferential rotation through a first transmission shaft, scraping plates move upwards from gaps between intercepting plates to fish up waste residues, and when the scraping plates reach the position close to a material containing box, an air spraying pipe sprays air to a guide plate to spray the waste residues downwards into the material containing box; then a second transmission shaft drives a spiral pushing rod to operate, waste residues are pushed to a discharging pipe and discharged and collected, waste liquid, waste residues and the like collected at a filter box can be repeatedly fed from a feeding pipe so as to better filter and separate the waste liquid and waste residues, and the device has the advantages of being good in filtering effect, high in separation efficiency and higher in practicability.
