Study On Productive New Process Of Tin Methanesulfonate

With the rapid development of electroplate and electronics industry, electroplate liquid of the higer quality is demanded urgently. The electroplate technology of the series of fluoroborate plating liquid and lead-tin alloys are used diffusely in traditional plating industry. The kinds of fluoroborate plating liquid have a lot of faults, for example, eroding the equipment seriously, harming the health of operator badly, polluting the environment severely, and difficult to deal with for the waste liquid, and so on. At present, the methyl sulphonate series products have been used by some developed countries for changing this state. The new green technology and new products are demanded urgently for our country, by which replace traditional productive technology and products.Tin methylsulfonate solution is used mainly in electroplate and electron industry etc.. replacing fluoroborate plating liquid. There is less reports that are vended for the synthetic technology of tin methylsulfonate in the country. To synthesize methylsulfonate tin by the means of the methylsulfonic acid and tin as raw material, the method is less reported in our country. So in the paper we have been researched for this synthetic technology in detail.Firstly, on the base of the organic synthesis reaction theory, we drew up the experimental scheme for the synthesis of methylsulfonate tin. Then with the orthogonal design method and the single-factor-experiment method, the key factors for affecting this complicate reaction were determined. The reaction temperature and material proportion influence on the reaction mainly. Furthermore we researched the influence of reaction temperature and material proportion on the reaction by the single-factor-experiment method. The product was approved with IR analytical method and thermal analysis method. The ideal synthetic process conditions were acquired in the experiment.In this better conditions, the product yield is up to 90 %, the product purity is up to 93 %, and unreacted methylsulfonic acid can be cycled for synthesis of methylsulfonate tin. The technology operation in this study is a green process, because it is easier operation, no harmful to one's health and no waste in this process.By the orthogonal design method and the single-factor-experiment method, we optimized the better process conditions of synthesizing methylsulfonate tin. Then the...
