Paragraph 0065; 0072, (2021/03/31)
The invention relates to the technical field of dihydric alcohol, in particular to dihydric alcohol containing disulfide bonds as well as a preparation method and application thereof. The structure ofthe disulfide bond-containing dihydric alcohol is shown as a formula (1) as the specification; the preparation raw materials of the disulfide bond-containing dihydric alcohol comprise a compound shown as a formula (2) and peroxide, wherein the formula (2) is shown as the specification; in the process of preparing the dihydric alcohol containing the disulfide bond, cheap raw materials are adopted,no catalyst is used, a one-pot reaction is adopted, and the method is simple in process, convenient to operate and easy to implement; a micro-channel mixing reactor is adopted, so that excessive polyether byproducts are prevented from being generated, and the purity is improved; meanwhile, the problem of product purity caused by constructing disulfide bonds by using polysulfide is avoided. The disulfide bond-containing dihydric alcohol can be applied to the fields of polyester, polyurethane and other materials, and is used for improving the performance of the materials.
