Problems solved by technology

Through the development of new material science and technology to solve the problems of resource shortage and environmental pollution, my country has formed a relatively complete material science and technology system, and has made great progress in the research and development of the material field. Some new material fields have obvious resource advantages and technologies. Advantages, but the ability of independent innovation is weak, and there are few new material products and technologies with independent intellectual property rights, especially in the lack of innovation in calcium carbonate powder and multi-purpose fluorescent whitening agent

Abstract

The invention provides a diphenylethene sodium disulfonate surfactant. The diphenylethene sodium disulfonate surfactant is characterized in that the structural formula of the diphenylethene sodium disulfonate surfactant is shown in formula 1 (as described in the specification). The invention aims to provide a diphenylethene sodium disulfonate surfactant as well as a synthesis method and application thereof. The synthesis method of the diphenylethene sodium disulfonate surfactant is simple and convenient, the raw materials are low in price, and the operation is simple and safe. The diphenylethene sodium disulfonate surfactant provided by the invention has strong ultraviolet absorption performance and strong whitening effect on calcium carbonate powder, and can obviously reduce the surface tension of water. The diphenylethene sodium disulfonate surfactant is a multipurpose surfactant and has great application value and popularization space.

Description

technical field [0001] The present invention relates to distyrene disulfonate sodium surfactant, in particular to the synthesis and application of distyrene disulfonate sodium surfactant. Background technique [0002] In my country's "Twelfth Five-Year Plan" new material development plan, the research and development of materials that are in harmony with resources and the environment and materials that reduce environmental pollution and are conducive to recycling are taken as the main assessment indicators. Through the development of new material science and technology to solve the problems of resource shortage and environmental pollution, my country has formed a relatively complete material science and technology system, and has made great progress in the research and development of the material field. Some new material fields have obvious resource advantages and technologies. Advantages, but the ability of independent innovation is weak, and there are few new material produ...
