Organic silicon compounds, and preparation method and application thereof

Abstract

The invention discloses organic silicon compounds. The organic silicon compounds have the structure shown in a formula (I), wherein a is equal to 0 to 40, b is equal to 0 to 30, c is equal to 0 to 40, a, b and c are all integers and the sum of a, b and c is more than 6. the invention discloses a method for preparing the organic silicon compounds, and the method comprises the following steps of: reacting alpha-hydrogen-omega-hydroxyl polyether with halogenated propylene which serve as raw materials in the presence of alkali metal hydroxides to form diallyl polyether; and reacting the obtained diallyl polyether with 1,1,1,3,5,5,5-heptamethyltrisiloxane in the presence of a Pt catalyst to obtain the finished product. The organic silicon compounds have the advantages of unique structure, low surface tension, no toxin and high oil-collecting effect, and can be widely applied to the field of oil spill pollution treatment in water areas.

Description

technical field The invention belongs to the technical field of organosilicon compound synthesis, and in particular relates to an organosilicon compound and its preparation method and application. Background technique Silicone surfactant is a new type of surfactant developed along with new silicone materials. Like fluorine-containing surfactants, it has won a broad space for survival and development with its unique properties since it came out. Now it has become an increasingly important special surfactant. Offshore oil exploration and transportation often cause oil spills and oil spills due to accidents or other technical reasons, which not only cause huge economic losses to enterprises, but also cause serious environmental pollution. After the oil spills in the water, it will spread out quickly and form a very thin oil layer, making recovery difficult. The oil collector based on surfactant can reduce the surface tension of seawater, reduce the area of ​​oil spill and fo...

AI Technical Summary

Problems solved by technology

The purpose of the present invention is to solve the problems of limited effect and inconvenient use of the oil-collecting agent in the prior art, and provide a novel organosilicon compound, which has a unique structure and is effective in driving various hydrocarbon oil spills. It has good effect, is easy to use, and is environmentally friendly, and can be used as an oil collector for oil spill treatment in waters
