The invention relates to a quick detergent for roadside adlets, which can quickly and efficiently remove roadside adlets on walls, bus stations and bulletin boards. The invention is characterized in that the detergent is prepared by mixing the following raw materials in parts by weight: 60-90 parts of solvent, 10-20 parts of surfactant, 5-10 parts of ionic liquid synergist, 6-8 parts of filler and 0.1-1 part of cetyl sodium sulfate. The solvent is a mixture of ethanol, ethyl acetate and deionized water in any ratio; and the surfactant is CH3O(CH3CH2CH2O)nCH2OCH3, wherein n=6-11. The detergent can quickly and efficiently remove roadside adlets on walls, bus stations and bulletin boards, is free of chemical components which are harmful to the environment and buildings, and can not do damage to the health of cleaning personnel and building surfaces.

The invention discloses a cynanchum otophyllum dispersible tablet and a preparation method thereof, relating to medicines. The cynanchum otophyllum dispersible tablet is made of the following raw materials by weight portions: 50-200 portions of an extract of cynanchum otophyllum total glucoside, 20-100 portions of an disintegrating agent, 1-10 portions of a lubricant and 1-20 portions of a surfactant, wherein, the disintegrating agent is CMS-Na, CCNa, PVPP, L-HPC and dry starch, the lubricant is magnesium stearate or talcum powder or superfine silica gel powder, the surfactant is SDS, sodium hexadecyl sulfate and sodium stearyl sulfate. The preparation method consists of the following steps: 20-200 portions of total glucoside of the cynanchum otophyllum by weight is taken out and sieved with a 100-mesh sieve; 20-100 portions of the disintegrating agent by weight and 1-10 portions of the lubricant by weight are taken out and respectively sieved with the 100-mesh sieve; 1-20 portions ofthe surfactant by weight is taken out and sieved with a 80-mesh sieve; then the sieved extract, the sieved disintegrating agent, the sieved lubricant and the sieved surfactant are ground and evenly mixed, and then the mixture is sieved with the 80-mesh sieve, and direct compression and sieving are carried out on the sieved mixture to obtain the dispersible tablet. The dispersible tablet has high dissolution and high bioavailability, can fully exert the drug action of the cynanchum otophyllum, and the preparation method is simple and feasible while suitable for industrialized production.

The invention provides a preparation method of a high-stability dibromohydantoin disinfection solution. The preparation method comprises the following steps: (1) mixing soluble alkali, 5,5-dimethylhydantoin and water to obtain a water solution; dropping monomer bromine a into the water solution while stirring to obtain a reaction solution; (2) adding a dispersant into the reaction solution obtained in the step (1) and stirring to dissolve the dispersant, and dropping monomer bromine b into the solution to obtain a solution, wherein the mol ratio of the monomer bromine b to the monomer bromine a in the step (1) is 1 to 1, the mass ratio of the dispersant to the reaction solution in the step (1) is (0.01-1) to 100, and the dispersant is one of sodium dodecyl benzene sulfonate, sodium hexadecanesulfonate, sodium octadecyl benzene sulfonate, lauryl sodium sulfate, cetyl sodium sulfate or octadecyl sodium sulfate; and (3) adding a stabilizing agent and a synergist to the solution obtained in the step (2) to obtain a mixed solution, thus obtaining the high-stability dibromohydantoin disinfection solution.
