Potasiuma'ākeka

Paʻakai a me nā mea kemika o aceticʻakika i kapaia acetates. Ka mea, iʻano nui hoʻohana like me ka mordant, a me a ka make i paa ma ka puluniu. Ma kekahi, potasiuma'ākeka (kahua hoʻonohonohoʻana inoa i loko o English - potasiuma'ākeka, hua'ōlelo'ālike - potasiuma paakai) mea he potasiuma paakai o aceticʻakika, i ka Nine Inch haʻilula CH3COOK. Molar nuipa Ua like ia 98,15 g. / Mol.

Ma lalo o maʻamau rula o ka potasiuma'ākeka mea he keʻokeʻo mea pōaka pauka i mea hygroscopic, no laila, i ka lewa hohola. Kona pa apŘ mea 1,57 g. / Cm³. I ka paʻakai o ka haiia wailana i loko o ka wai: 100 ml hoike iki aku ma mua o 200 g. O ka paʻakai ma 20 ° C a me 492 g. O - ma 62 ° C. Potasiuma'ākeka Ua hooholo koke wailana ma ka waiʻona (metanola a me ka ethanol), a ma ka ammonia, mea insoluble i loko o Etera, a acetone. I ka wela o ka decomposition o potasiuma'ākeka hua hoʻohui 292 ° C.

Hoomakaukau'ākeka potasiuma reacting ka walaʻauʻana i huiʻia e like me potasiuma hydroxide (KOH) ole potasiuma kalepona (K2CO3) me aceticʻakika kūpono neutralization naoh: KOH + CH3COOH → CO2 + CH3COOK + H2O a papalua mail: + CH3COOH → CO2 + CH3COOK K2CO3 + H2O . No ka mea hiki ke hooheheeia e ku ana ma ka electrochemical hopena ua haʻalele o ka hydrogen, e laʻa me, potasiuma a makanekiuma, wehewehe aku ma ka naoh me nāʻakika ole-oxidizing. Oia nāʻakika nā aceticʻakika. I ka mea hana, e laʻa me, makanekiuma, makanekiuma'ākeka ua loaa: mg + 2CH3COOH → mg (CH3COO) 2 + h2. Akā, i kēia hana, aole mea hiki ana no ka makaukau o ka makanekiuma a potasiuma paakai o aceticʻakika. Ma ka noa ana, i kēia mau mea hiki ke hooheheeia e mai nei ma ke ano maoli, a me ka potasiuma no o ko lākou reactivity reacts ka haiia me ka wai, a oxidized ma ka lewa ka oxygen. Akā, ia mea he loa pipiʻi metala, a ua hoʻohana 'ia i emi pinepine ia ma mua o paʻakai.

potasiuma'ākeka e like me GOST 5820-78 ua hoʻohana 'ia i loko o ka? iecaianoaaiiie o ke aloha silikone polymers (silicones - kuhikuhi ana i loko o ka manufacturing o ka pīlali huahana nui a me ka'ōleloʻana mai iā). Potasiuma'ākeka i hoʻohana ua like me ka hōʻeleu i loko o ka? Iecaianoaaiiie o polyurethanes. ʻO kekahi mea nui 'āpana o ke noi ana o potasiuma'ākeka - kona hoʻohana like me ka deicer. Kēia mea kemikala i ka helu o nā pono (ka mea i emiʻano pākīkē ma ka manao o ka lepo) a no ia mea, replaces makanekiuma koloriside paha kalipuna i loko o ka aaioee o runways ma airports, a me kona corrosive 'ole ma na mea hiki ke hooheheeia ka emi o na chlorides. Potasiuma'ākeka mea e noho malie hoi e ka hapanui surfaces, a me pōhaku puna, mea hiki ke hooheheeia, lāʻau, eioea, LAWN a me ka mea kanu. Akā, mahope mai o kona kumukuai mea kiʻekiʻe ma luna o ia o chlorides, i ka la mahope pinepine he makemake ko, hoʻowahāwahā i ka? Aneie aʻe 'ana, a hoonuiia Wear o ka lako a pan. Eia hou kekahi, potasiuma'ākeka, mea he pono ke ahi-extinguishers, a ua hoʻohana 'ia e kinai ahi. Ua Ua hoʻohana 'ia no ka kinai pū kaʻaila.

Potasiuma'ākeka ua hoʻohana 'ole wale ma ka hanalima palapala koho akā, no hoi ma ka lapaau a me ka meaʻai hana (ka hoʻokō preservative E261, ua hanaʻia e like me GOST 5820-78). No ka nane, kekahi paakai o ka carboxylicʻakika - pōhaku'ākeka - i hanalima noi. Ua Ua loaa wale ma ka keʻena hoʻokolohua kūlana ma ka hopena o ka aceticʻakika ma ka pōhaku paʻapuna. Ke naoh Ua hoomau a piha hoʻopau o ke kalapona'okikene lua: CaCO3 + 2CH3COOH → CO2 ↑ + (CH3COO) 2Ca + H2O. Hoʻohana 'ia (CH3COO) 2Ca wale me he ai mea hoʻonui E263 no ka mea, (e like me CH3COOK) mea he pono ka preservative.

I ka hope Inc no ka iapaau ana o diabetic ketoacidosis hoʻohana potasiuma'ākeka. Ka hopena hiki ke hooki ketoatsidoticheskaya diabetic coma, a e hiki mai i ka hopena o metabolic acidosis (pH emi), kena ae la ia e metabolic kāna hana ma muli o ke pancreatic hōmona deficiency (insulina). High nā hoʻohui like ana o ke koko a me ka monakō koko ketone kino i mea me ka nui loa ma luna ma mua o ka physiological cia ketoatsidoticheskaya hiki aku ai i ka diabetic coma. potasiuma'ākeka, ua hoʻohana 'ia e like me ka ai mea hoʻonui, e like me ka hiki ke hoemi i ka nui o kaʻakika e decompose bicarbonate. No keia kumu, ka mea, ua hoʻohana 'ia e pono hoʻomanawanui iki mai i kaʻike, o keʻano mua o ka mimikō.
