Dodine, colorless or white, crystalline solid, soluble in water and alcohol. Stable under normal temperature and pressure, avoiding oxide contact. Duoguoding is a non inhaling protective fungicide. Duoguoding can prevent and control a variety of major mold diseases on fruit trees, vegetables, nuts, ornamental plants and shade trees. In addition, it is used for disinfection and sterilization of industrial water treatment agents, detergents, seed treatment agents, women's and children's supplies and food packaging. The center has successfully developed a new process for the synthesis of dodecadine from urea, which has the technical advantages of low cost and high quality.
Dodecadine acetate, also known as Dodine, is a widely used surfactant. It is mainly used as a low toxicity fungicide to prevent and control diseases of fruit trees and vegetables, mainly for protection, rather than no internal absorption. The sterilization mechanism is to destroy the permeability of cells, resulting in the extravasation of cell contents and cell death.
Dodine is a widely used surfactant. It is mainly used as pesticide and belongs to low toxicity fungicide. Protective fungicides can be used to control a variety of major fungal diseases on fruit trees, vegetables, nuts, ornamental plants and shade trees (such as scab of apples and pears, leaf spot of cherries, l disease and brown spot, tomato early blight, kenaf anthracnose, etc.); It can be used as a component of double effect liquid micro fertilizer and as a fungicide component, so that the fertilizer can achieve the dual effects of preventing bacterial and viral diseases and regulating and promoting crop growth; Industrial water treatment agent, used in water systems of pools, cooling towers, cooling pipes, swimming pools and other similar industrial and civil facilities, is very effective in inhibiting the growth of various forms of algae microorganisms in open systems; Used as detergent ingredient. Used for washing and nursing hair;
A synthetic method of Dodine, which takes guanidine hydrochloride as the starting material, reacts with chlorododecane to prepare intermediate a, then adds strong alkali aqueous solution to intermediate a for reaction, then adds glacial acetic acid for reaction, and after treatment, to prepare the target product doxycycline. This synthetic method has the advantages of easy availability of raw materials, few reaction steps, mild reaction conditions, simple operation, high yield, and is a ring earth friendly synthetic method. Therefore, it is suitable for large-scale industrial production. It has good application prospects and market potential.
