The invention relates to a preparation method of a blue light luminous fiber. The preparation method comprises the following steps: firstly, mixing 0.1 to 0.5 weight part of triphenyl iodine hexafluoroantimonate photoinitiator with 5 to 10 weight parts of SrAl2O4:Eu and Dy luminescent material and 20 to 40 weight parts of fiber forming polymer base material, granulating by adopting a twin-screw granulator to obtain luminescent master batches for spinning; secondly, pre-drying the luminescent master batches for spinning obtained in the first step and then performing melt spinning to obtain the blue light luminous fiber. The luminous fiber obtained by the preparation method absorbs visible light for 10 minutes, and can continuously emit light in a dark state for 10 hours or above; the luminous intensity can maximally reach 1.5 to 3cd/m ; emitted blue light of 430 to 450nm is one of three primary colors; any one complex color luminous fiber can be prepared by compounding the blue light luminous fiber with one or two of a red luminous fiber and a green luminous fiber, and the application field of the luminous fiber can be widened.

The invention discloses a preparation method of symmetrical aryl iodide onium hydrochloride, relating to the field of organic synthesis. The symmetrical aryl iodide onium hydrochloride is obtained by the following steps of: reacting aromatic hydrocarbons (benzene, toluene, tert-butylbenzene, dodecyl benzene and the like) serving as raw materials with potassium iodate in the presence of concentrated sulfuric acid by taking acetic anhydride or acetic acid or a mixture thereof as a solvent to generate corresponding aryl iodide onium hydrochloride; and performing ion exchange in a sodium chloride aqueous solution to obtain the symmetrical aryl iodide onium hydrochloride. In order to overcome the defects of the prior art, the invention provides a method which has high yield and is convenient for realizing industrial production. The method comprises the following steps of: at an experimental reaction stage, putting potassium iodate and acetic anhydride (acetic acid) into a reaction bottle, dropwise adding concentrated sulfuric acid slowly and dropwise adding aromatic hydrocarbon for reacting; and during preparation of iodine onium hydrochloride at the end of the reaction, extracting a reaction liquid with an extracting agent, removing unreacted raw materials or other byproducts with high lipid solubility and separating a lower water layer and the sodium chloride aqueous solution out for ion exchange to directly obtain the symmetrical aryl iodide onium hydrochloride at high yield.

The present invention relates to a synthesizing method for 4,4 double hexabromocyclododecane alkyl benzene iodine fluorin antimonite, which is made with the following steps: (1) 4,4 double hexabromocyclododecane alkyl benzene iodine is prepared by the reaction with barium chloride under the function of vitriol taking detergent alkylate and potassium iodate as the material, and acetic anhydride as the solution; (2) 4,4 double hexabromocyclododecane alkyl benzene iodine fluorin antimonite is prepared by the ion reaction between 4,4 double hexabromocyclododecane alkyl benzene iodine and fluorin potassium metaantimonate in cyclohexane, chloroform or dichloroethane solution agent. The 4,4 double hexabromocyclododecane alkyl benzene iodine fluorin antimonite synthesized by the present invention has much better solidified performance to the resin.
