Potassium acetate

Neetyuwa kunye esters of acetic acid zibizwa ngokuba acetates. ikakhulu zisetyenziswa njenge mordant, awanyakazela ngayo idayi njo ifayibha. Ngokukodwa, potassium acetate (igama oluthe tye IsiNgesi - acetate Potassium, ntonye - ityuwa potassium) is a ityuwa potassium of acetic acid, uye CH3COOK ifomula imichiza. mass izinyo ilingana 98,15 g / Mol.

Phantsi kweemeko eziqhelekileyo le acetate potassium yi ngumgubo crystalline emhlophe ukuba hygroscopic, ngoko umoya kwaqhenqetha. mninzi wayo 1,57 g / cm³. Le netyuwa lula enyibilikayo emanzini: 100 ml iyachithakala kancinci ngaphezulu kwe-200 g ye-lweTyuwa-20 ° C ne 492 g ye - ngo-62 ° C. Ipotaziyam acetate kuba lula enyibilikayo butywala (methanol kunye ethanol) kwaye ammonia, kuba ezingenakunyibilika kwi kaEtere kunye acetone. Iqondo lobushushu yokubola potassium acetate dibanisa 292 ° C.

Fumana acetate potassium impefumlelwano iikhompawundi ezisisiseko ezifana ezifana potassium hayidroksayidi (Koh) okanye potassium carbonate (K2CO3) nge-acetic acid kubangele indlela neutralization: Koh + CH3COOH → CO2 + CH3COOK + H2O okanye exchange kabini: K2CO3 + CH3COOH → CO2 + CH3COOK + H2O . Kuba iintsimbi emi kuthotho electrochemical ekhohlo hydrogen, umz, potassium okanye nemagnesium, esibonakala asabela nee-asidi non-oxidizing. Ezo asidi ziquka acetic acid. Xa esinxibelelana, umz, nemagnesium, nemagnesium acetate ifunyenwe: MG + 2CH3COOH → MG (CH3COO) 2 + H2. Kodwa le ndlela akukho ukusetyenziswa epraktikhali lokulungisa wemagniziyam okanye potassium ityiwa acetic acid. Xa urhulumente simahla, lwezi methali musa ezikhoyo kwindalo, yaye potassium ngenxa reactivity lwabo iyazithethe- lula ngamanzi oxidized yi-oksijini emoyeni. Kodwa kuthiwe sisinyithi imali eninzi kakhulu yaye usetyenziswa kancinci qho ngaphezu sodium.

potassium acetate njengako GOST 5820-78 lisetyenziswa ekuvelisweni Iipholima lesilicon organic (silicones - ulwalathiso ukuvelisa iimveliso Polymer ebalulekileyo ithembisa). Ipotaziyam acetate isetyenziswe kuvala ekuvelisweni polyurethanes. Enye indawo ebalulekileyo ukusetyenziswa potassium acetate - ukusetyenziswa kwayo nje deicer. Le reagent inenani yeenzuzo (lingaphantsi ndlongondlongo ngokuphathelele umhlaba) kwaye ngoko indawo wemagniziyam chloride okanye calcium ekusetyenzweni moya kwizikhululo zeenqwelo-moya, kunye neziphumo zayo onakalisayo kwi iintsimbi lingaphantsi kwe-kloride. Ipotaziyam acetate ukuba akanangozi imiphezulu ezininzi, kuquka izinto, intsimbi, iinkuni, emijelweni, utyani, nezityalo. Kodwa ukusukela ixabiso layo iphezulu kunale kloride, le yokugqibela ezithandwayo, nangona ukunyhashwa yokusingqongileyo kunye nokwanda banxibe kwezixhobo. Ukongeza, potassium acetate, kuba umlilo-mlilo olusebenzayo kwaye kusetyenziswa ukucima umlilo. Isetyenziswa zokucima ioli.

Ipotaziyam acetate isetyenziswa nje kuphela izicwangciso zoshishino kodwa amayeza kunye noshishino ukutya (olusebenzayo E261 ukubola, eyakhiwe ngokwemigangatho GOST 5820-78). Thelekisa, omnye ityuwa carboxylic acid - Calcium acetate - izicelo akukho mveliso. Le zifumaneka kuphela kwiimeko kwelabhoratri ifuthe acetic acid kwi calcium carbonate. Indlela abasabela kuyaqhutywa de ukupheliswa ngokupheleleyo carbon dioxide: CaCO3 + 2CH3COOH → CO2 ↑ + (CH3COO) 2Ca + H2O. Used (CH3COO) 2Ca kuphela nje additive ukutya E263 kuba (njengoko CH3COOK) yinto ukubola olusebenzayo.

Xa therapy replacement ngenxa yonyango ketoacidosis seswekile kusetyenziswa potassium acetate. Isiphumo ingathintelwa ketoatsidoticheskaya isiqaqa seswekile, enokuthi yenzeke ngenxa yokuba lactic pathways (pH ukuhla) okubangelwa ukuphazamiseka pathways ngenxa pancreatic hormone ngxaki (insulin). High lamanani igazi glucose ketone imizimba eziba ngaphezulu kakhulu kunokuba bokuphila ixabiso ketoatsidoticheskaya kukhokelela isiqaqa seswekile. potassium acetate, isetyenziswa njenge additive ukutya, njengoko ikwazi ukunciphisa inqanaba asidi ukuba ukubola yesoda. Ngenxa yesi sizathu, lisetyenziswa ukunyanga izigulana kunye lokufunyaniswa Uhlobo lokuqala seswekile.
