Ndi sodium nthochi

mankhwala A amene mankhwala ndiyo njira - CH3COONa - ndi sodium wochuluka mchere wa asidi acetic kapena ndi sodium nthochi. Amagwiritsidwanso mayina a m'kaundula wa mayiko wa zowonjezera chakudya mu gawo chiwerengero E-262.

thunthu ndi Krustalo, mithunzi ya mtundu yomwe ikhoza kukhala mu osiyanasiyana kuchokera wotumbululuka zachikasu zofiirira kwambiri. Chilengedwe zoweta anagwiritsanso ntchito dzina la nthochi ndi sodium. Thunthu ndi sodium nthochi - nonflammable, chitetezo gulu anatumizidwa ku kalasi yachinayi. Sodium nthochi kuphulika-umboni ndipo ali otsika kawopsedwe, m'njira zambiri chifukwa ntchito yake lonse kupanga mafakitale ndi tsiku.

Iwo akamagwira anachita ndi asidi NaOH kapena Na2CO3 acetic kapena esters asidi izi. Yopangidwa mankhwala, kawirikawiri olimba. Mu mafakitale wa kachigawo Unyinji wa mchere m'chigawo anhydrous amamasulidwa ku bwinobwino osachepera 50%. Othandiza ntchito pamafunika mankhwala phunziro kwa zinthu zina, mwachitsanzo, kutentha malire kugwilizana (yozungulira kutentha sayenera upambana madigiri 5).

Makampani mankhwala zambiri zofunika n'chongoletsa zinthu zikuwononga ndi mankhwala. chuma china asidi sulfuric. Kuti n'chongoletsa izo, ndi nthochi ndi sodium ntchito, kuikapo maganizo asidi sulfuric kwatha kupanga oksosoli Na2SO4, zinthu kugwera pansi pa neutralization anachita kupanga precipitate woyera. Izi zosiyanasiyana kuopseza kuteteza poyizoni ndipo amayaka zinachitikira kutayikira asidi sulfuric.

Monga tanenera kale, thunthu chimagwiritsidwa ntchito zosiyanasiyana. Makampani nsalu ntchito basi zochokera luso n'chongoletsa zotsala za asidi sulfuric zinyalala mu mpweya mbewu, komanso kupanga zosiyanasiyana utoto aniline gulu (ntchito ngati photoresist ndi - photosensitive ❖ kuyanika). Kupanga kupanga labala ntchito nthochi ndi sodium zochokera umatha m'mbuyo pa vulcanization lapansi.

Makampani chakudya, sodium nthochi ntchito usawonongeke.

Luso ndi sodium nthochi chimagwiritsidwa ntchito monga zina kuti antimoroznoy zosiyanasiyana zimapangitsa concretes ntchito yomanga monolithic nyumba simenti, ndi kuchita ntchito zina nyumba kugwirizana ndi kudindidwa ndi nyumba kulimbitsa pa otsika kutentha. Mfundo imeneyi ndi chifukwa luso kuletsa yozizira koopsa wa thunthu la kasakaniza konkire pafupifupi m'zinthu zonse wa zomangamanga - kayendedwe, nyumba kuteteza, zomangamanga ndi ena. Makamaka, sodium nthochi kumathandiza zosakaniza settable pa otsika kutentha, popanda kutsitsa khalidwe lawo ndi wopanda complicating ndondomeko kukonzekera awo. ntchito zake kwambiri imafoola zikuwononga yomanga kusonkhana ndondomeko komanso kumathandiza kuti mphamvu ya konkire.

Kufalitsidwa ndi ntchito ya nthochi ndi sodium mankhwala ndi mbali kupanga okodzetsa, komanso alkalinization wa chamoyo mu hyponatremia ndi kagayidwe kachakudya acidosis.

Pezani zinthu zimenezi zingakhale ndi kunyumba. Bwanji Mng'oma ndi sodium nthochi kunyumba? Ndi zovuta. Tengani 1 makilogalamu koloko wamba ndi 1 lita imodzi vinyo wosasa. Kenako pang'onopang'ono, kusakaniza iwo mu chidebe galasi, ndondomeko adzapitiriza bola mpaka ukali mabasi. Muli pansi pa chotengera adzakhala monolithic hydrated sodium wochuluka nthochi. Ndiye iwo ayenera usavutike kusungunula kwathunthu ndi kuchotsa precipitate ndi kusefera. Zopezera mtundu woyera galasi osungunula ayenera utakhazikika kwa firiji pamaso ma CD. Mwalandira mankhwala mu madzi mawonekedwe, ndi kupereka mawonekedwe olimba lophweka - m'pofunika mu galasi madzi kuwonjezera pang'ono za sodium wochuluka nthochi chomwecho. Choncho, munthu akhoza kuchititsa angapo Overstore zinthu, malingana ndi zomwe a boma akaphatikiza n'kofunika.
