Production operation
1, the preparation of crude:
⑴ neutralization: put the raw material potassium hydrogen tartrate into the tank, add twice the amount of water, boiled with steam to boil, in constant stirring, slowly add dry sodium carbonate and neutral until it does not produce bubbles so far. At this time the solution was tested with litmus paper tested neutral.
⑵ filter: hot filter bag. The filtrate should be transparent or nearly transparent.
⑶ concentrated, crystallization: the filtrate into the enamel barrels, heated and concentrated to the solution concentration of 38-42 Baume degrees, removed in the tray (thickness of 15-20 cm is appropriate), at room temperature for 24 hours That is natural crystal. Separate the mother liquor, remove the crystal, washed once with cold water (water and mother liquor combined recovery), that is, potassium tartrate crude products.
2, the purification of crude products: the crude product plus the amount of water (1-2 times) heated to dissolve, add activated carbon decolorization (activated carbon added amount of sample volume of 5-15%) for 10 minutes after mixing, filtration (the filtrate with crude crystallization treatment Method, the recrystallization, the crystal should be colorless and transparent) to separate the mother liquor, washed dry or dried at 50 ℃ finished product.
