The invention discloses preparation of a water-soluble metal-organic framework composite material and application thereof in detecting the concentration of fluorine ions in water. The preparation comprises the following steps of: preparing a urea solution; adding aluminum trichloride into ultrapure water, carrying out ultrasonic treatment until the aluminum trichloride is completely dissolved, adding 2-aminoterephthalic acid under a stirring condition, and stirring until the 2-aminoterephthalic acid is completely dissolved to obtain a mixed solution; slowly dropwise adding the urea solution into the mixed solution, and stirring to obtain a reaction solution; carrying out heat preservation after the reaction solution is heated, cooling, centrifuging, washing precipitates, and carrying out centrifugal separation to obtain a first product; and dispersing the first product into N, N-dimethylformamide, stirring, carrying out centrifugal separation to obtain a second product, dispersing thesecond product into methanol, stirring, carrying out centrifugal separation, and carrying out vacuum drying to obtain the water-soluble metal organic framework composite material. The composite material is used for detecting the fluorine ion concentration in water. The fluorescent probe prepared by the preparation method has a nanosheet microstructure, is easy to store, and has excellent solubility and good stability in water.

The invention relates to vat dye and a preparation method thereof, in particular to vat olive MW dye with low heavy metal and a preparation method of the vat olive MW dye. The preparation method comprises the specific steps as follows: aluminum trichloride and sodium chloride are heated and subjected to heat preservation for 3 hours, then a sulfonating agent chlorosulfonic acid and olive T raw powder are added, the vat olive MW dye is prepared by controlling the reaction temperature and time, then the vat olive MW dye is added to an acidized bottom water compounded by sulfuric acid and hydrochloric acid, beat, heated, subjected to acid pickling, filtered and washed by water to obtain the vat olive MW dye with low heavy metal, the heavy metal content in the dye is low, the Fe content is smaller than or equal to 800 PPM (parts per million), the Cu content is smaller than or equal to 200 PPM, the color is fresh bright, the fastness is excellent, and meanwhile, a product does not require sanding, so that the production cost can be saved by about 30%.

The invention provides a preparation method for rosolic acid, wherein the preparation method comprises the following specific preparation steps: (1) heating phenol to melt into a liquid, then adding an aluminum trichloride powder, intensely stirring to make the solid evenly dispersed in phenol, heating the system to 100 DEG C, then adding carbon tetrachloride, carrying out a reaction for 8 hours and then stopping heating; and (2) cooling to room temperature by allowing to stand, washing with water for three times, finally washing with diethyl ether to obtain a red solid product, collecting thesolid product, and drying at the temperature of 60 DEG C, to obtain the rosolic acid. The preparation method adopts aluminum trichloride as a catalyst and phenol and carbon tetrachloride as the raw materials to synthesize the rosolic acid, and has the advantages of high operability and short reaction time; the yield can be increased to 75% or more, and the product has high sensitivity and is suitable for needs of large-scale industrialized production.

The invention discloses a preparation method of phthalocyanine green G. The preparation method comprises the following steps: adding water into a reactor, adding selected aluminum trichloride into the reactor to carry out reactions, then adding copper phthalocyanine and cuprous chloride into the reactor, mixing, carrying out reactions, then introducing chlorine gas into the reactor, carrying out acid and alkali washing, finally washing the reaction product by a filter press to obtain a semi-finished product, drying, grinding, and filling the powder into bags to obtain finished products. The product is processed by acid and alkali, thus the impurities in the product are few, the physical properties are stable, the fading of the product is also prevented, during the production process, the product is processed by a filter press, the environment pollution is little, the product can be concentrated in the filter press, and thus the waste is reduced.

The invention relates to the field of waterproof coatings, and discloses a nano densified polymer-based waterproof coating and a preparation method thereof. The preparation method comprises the following steps: (1) sequentially adding aluminum trichloride and nano zeolite powder into water, and filtering and drying to obtain an aluminum trichloride/zeolite powder composite material, (2) carrying out ball milling treatment on the composite material, then adding polyvinyl alcohol and water, and uniformly stirring to obtain a polyvinyl alcohol coated aluminum trichloride/zeolite powder compositematerial, and (3) uniformly mixing the composite material with barite powder, nano silicon dioxide, polymer redispersible rubber powder, Portland cement and a thickening agent to obtain the nano densified polymer-based waterproof coating. The polymer-based waterproof coating prepared by the invention contains the polyvinyl alcohol-coated aluminum trichloride/zeolite powder composite material, so that the defect can be slowly filled with the stone aluminum trichloride when the coating has the defect, and meanwhile, a gel film is formed to seal micropores, so that a waterproof layer is denser, and the waterproof performance of the waterproof coating is improved.
