Potassium Humate Storage And Transportation

Aug 17, 2017

    Potassium hydroxide (chemical formula: KOH, amount: 56.1) white powder or flaky solid. A melting point of 380 ° C, a boiling point of 1324 ° C, a relative density of 2.04 g / cm 3, a refractive index n20 / D1.421, and a vapor pressure of 1 mmHg (719 ° C). With strong alkaline and corrosive. Easy to absorb moisture in the air and deliquescence, absorption of carbon dioxide from potassium carbonate. Dissolved in about 0.6 parts of hot water, 0.9 parts of cold water, 3 parts of ethanol and 2.5 parts of glycerol. When dissolved in water, alcohol or treated with acid to produce a lot of heat. The pH of the 0.1 mol / L solution was 13.5. Medium toxic, half lethal dose (rat, oral) 1230mg / kg. Soluble in ethanol, slightly soluble in ether. Has a very strong alkaline and corrosive, its nature and caustic soda similar. Medium toxic, half lethal dose (rat, oral) 1230mg / kg.

Application areas

1, used as a desiccant, absorbent, for the production of oxalic acid and a variety of potassium, but also for electroplating, sculpture, lithography

2, mainly used for the production of raw materials such as potassium, such as potassium permanganate, potassium carbonate and so on. In the pharmaceutical industry, for the production of potassium boron, spironolactone, heparanol, testosterone propionate and so on. In the light industry for the production of potassium soap, alkaline batteries, cosmetics (such as cold cream, cream and shampoo). In the dye industry, for the production of reducing dyes, such as the reduction of blue RSN and so on. In the electrochemical industry, for electroplating, sculpture and so on. In the textile industry, for printing and dyeing, bleaching and mercerizing, and a large number of used for the manufacture of man-made fibers, polyester fiber main raw materials. In addition, it is also used for metallurgical heaters and leather degreasing and so on.

3, chemical raw materials, for medicine, household chemicals and so on.

4, used as analytical reagents, saponification reagents, carbon dioxide and moisture absorber.

5, the chemical industry for the manufacture of washing soap, shampoo soap, cream, cream, cream, shampoo and other raw materials. The pharmaceutical industry for the manufacture of progesterone, vanillin and other raw materials. The dye industry is used to make melamine dyes. The battery industry is used to make alkaline batteries

Content analysis

Accurately weighed the sample about 1.5g, dissolved in 40ml new boiled and cooled water, cold to 15 ℃, plus phenolphthalein test solution (TS-167) a few drops, with 1mol / L sulfuric acid titration. When the pink color disappears, record the amount of acid consumed, add a few drops of methyl orange test solution (TS-148), continue to titrate to show a continuous non-fading pink. Record the total volume of acid required for titration. Per 1 mol / L sulfuric acid equivalent to the total amount of alkali (in KOH) 56.11mg.

Storage and transportation

1, transport Note: rail transport, steel drums can be used to transport the car. The packaging should be complete and the load should be safe. During transport to ensure that the container does not leak, do not collapse, do not fall, no damage. It is forbidden to be mixed with combustible or combustible, acid, edible chemicals and so on. Transport vehicles should be equipped with leakage emergency handling equipment;

2, storage Note: stored in a cool, dry, well-ventilated warehouse. Away from fire, heat. The humidity in the reservoir is preferably not more than 85%. The packaging must be sealed and not damp. Should be easy with (can) fuel, acid and other separate storage, avoid mixed storage. Storage area should be equipped with appropriate materials to contain spills;

3, the packaging method: solid can be loaded into the 0.5 mm thick steel drum in the sealed, net weight of not more than 100 kg per barrel; plastic bags or two layers of kraft paper bags outside the full opening or in the open steel drum; threaded glass bottles, Plastic bottles or tin-plated steel drums (cans) outside the floor plate box, fiberboard box or plywood box; tin thin Steel drums (cans), metal buckets (cans), plastic bottles or metal hoses outside corrugated boxes.
