    Product Overview:

    Disodium EDTA is a tasteless, odourless or slightly salty white or creamy white crystal or granular powder, odourless and tasteless. It is soluble in water and extremely insoluble in ethanol. It is an important chelating agent, can chelate the metal ions in solution. It prevents metal-induced discolouration, deterioration, turbidity and oxidative loss of vitamin C. It also improves the antioxidant property of fats and oils (trace metals in fats and oils, such as iron, copper, etc., have the effect of promoting the oxidation of fats and oils).

    Edta Disodium Powder Usage and Synthesis.

    Of the salts of ethylenediaminetetraacetic acid, the disodium salt is the most important. It is an important complexing agent. Used in chemical copper plating, gold plating, lead-tin alloy plating, electrochemical polishing of steel parts and silver plating of copper parts before the solution, can also be used instead of EDTA-Na.

    It is also used in detergent, liquid soap, shampoo, agricultural chemical spray, bleaching and fixing solution for colour photographic material processing, water purification agent, PH adjusting agent, coagulant inhibitor and so on. In styrene-butadiene rubber polymerisation with the reduction of the reduction of the initiation system, disodium EDTA as part of the active agent, mainly used to complex ferrous ions, control the speed of polymerisation reaction.

    Uses and functions of Edta Disodium.

    Disodium EDTA is used as bleaching and fixing solution for colour photographic material processing, and also used as water purifier, pH adjusting agent, chelating agent, polyvalent chelating agent and coagulation inhibitor. It is also used in textile printing and dyeing, detergent, metal coating and metallurgical industry.

    Edta Disodium

    Preparation method of Edta Disodium.

    Product method of Bulk Edta Disodium Powder.

    Sodium chloroacetate is condensed with ethylenediamine and acidified to obtain ethylenediaminetetraacetic acid, which is then neutralised with sodium hydroxide. Dissolve the crude product in 10 times water, add equal volume of ethanol to precipitate disodium salt, then filter and wash.
