Dear Sir, we have been a professional supplier in water treatment chemicals in China for many years, in the following we list currently our popular exporting products as follows:CAS NO.:7705-08-0 Molecular Formula:FeCl3;Folecular Weight:162.20
1.Ferric Chloride Anhydrous 98%： FeCl3 ≥98%； FeCl2 ≤1.0%；Insoluble matter in water ≤0.5% Ferric Chloride Anhydrous 96% ：FeCl3 ≥96%；FeCl2 ≤2%；Insoluble matter in water ≤1.5% Appearance: greenish-brown crystal. Properties: strong humidity--absorbability, and can produce its dihydrate and hexahydrate. Easy soluble in water, ethanol,acetone, also in liquid sulfur dioxide, ethylamine, aniline; but insoluble in glycerol, or phosphorus trichloride. Its aqueous solution is acidic. Usage: Especially for water-treatment in industries, corrosive for electronic printed board, chlorinating agent in metallurgical industry, oxidant and mordant in dye industry, and catalyst, oxidant, and chlorinating agent in organic synthesis, and also for making ferric salt, pigment as raw material. 2.Ferric Chloride 45%：FeCl3 ≥40%；Density (25°C), g/cm3 ≥1.4；FeCl2 ≤0.4%；Insoluble matter in water ≤0.5%；Free acid ≤0.5% Ferric Chloride is mainly used for the engraving etching of electronic circuit board or purify drink water and treat waste water 3.Ferric Chloride Hexahydrate： Assay [FeCl3] /% ≥99.0；Water insoluble/% ≤0.01；Free acid(HCl)/% ≤0.1；Sulfate (SO4)/% ≤0.01； Nitrate(NO3)/% ≤0.01； Ammonia not sediment/% ≤0.1 Widely used in water treatment, organic synthesis catalyst.
