Good quality Sodium tripolyphosphate 7758-29-4
Basic Info
Model No.: CAS NO 7758-29-4
Product Description
Good quality Sodium Tripolyphosphate 7758-29-4 Production methods 1. By Disodium Hydrogen Phosphate and sodium dihydrogen phosphate mixed heated to 110 ℃ dehydration, continue heating to 540 ~ 580 ℃, dehydration and become stable grain type; Such as heated to 620 ℃ above, after melting temperature to 550 ℃, and then cooled in the air, is disintegrated into stable powder type. Add ethanol to an aqueous solution without water. When the Phosphoric Acid anhydride is melted by melting tank, it flows into the combustion furnace and the phosphorus is oxidized and then precipitated. To cool and remove the phosphoric anhydride (P2. O5). The phosphoric anhydride and the soda are mixed into the graphite crucible after being mixed in a blender with a solid base of 0.8(mol). In 750 ~ 800 ℃ under the indirect heating, dehydration after polymerization, sodium hexametaphosphate molten body. Put it in a cooling plate and quench it with a clear glass of sodium hexametaphosphate. 2. (1) will be 2 mol, disodium hydrogen phosphate and 1 mol, uniformity of powder mixture of sodium dihydrogen phosphate [or dry Na: P = 5:3 (mole ratio) of sodium phosphate] into the platinum plating, under 540 ~ 580 ℃ heating dehydration two h, available Ⅰ type sodium tripolyphosphate. ... use It is used as softener, detergent, preservative, cement accelerator, fiber and bleaching agent. It is also used in medicine, food oil, printing and dyeing, tanning, papermaking and so on.
