Sodium acetate

Into ifomula kabani kumakhemikhali - CH3COONa - usawoti sodium ka acetic acid noma sodium acetate. Liphinde bhalisiwe kwirejista ngamazwe Izithako ukudla ngaphansi inombolo okuyingxenye E-262.

Ingqikithi kuyinto crystal, shades umbala okungase uhla kusuka ugodo ephuzi kuya nsundu ezijulile. Imvelo yasekhaya liyasetshenziswa ngegama sodium acetate. Ingqikithi sodium acetate - nonflammable, ukuphepha ngezigaba eyabelwe efunda ibanga lesine. Sodium acetate ukuqhuma-ubufakazi futhi has ubuthi ongaphakeme, kuba ngezindlela eziningi ngenxa yokusetshenziswa kwawo kabanzi ukukhiqizwa yezimboni nokuphila kwansuku zonke.

It is etholwe ukuphendula NaOH noma Na2CO3 acetic acid noma esters lokhu acid. izidakamizwa Produced, ngokuvamile okuqinile. Esikhathini ukukhiqizwa yezimboni of the ingxenyenamba mass sikasawoti isimo anhydrous isethelwe ngokuvamile hhayi ngaphansi kuka-50%. Ngokoqobo kudinga ketshezi ngokuya ngemibandela ethile, isib, izinga lokushisa imingcele ukuhambisana (lokushisa kuma kumele singeqi 5 degrees).

Ngokuvamile umkhakha chemical kuyadingeka iwukudambisa izinto ezonakalisayo kanye compounds. Omunye izinto ezinjalo kuba sulfuric acid. Ukuze iwukudambisa it, kanye sodium acetate isetshenziswa, kanzulu sulfuric acid is neutralized ukwakha oksosoli Na2SO4, izinto ziyethe ngesikhathi yokusabela neutralization ukwakha ziyazika emhlophe. Lezi ukusabela usongo ukuvimbela ubuthi kanye ukusha esimweni ukuvuza ka-sulfuric acid.

Njengoba sekuphawuliwe kakade, izidakamizwa is kabanzi emikhakheni ehlukahlukene. Basembonini yendwangu ulisebenzise nje esekelwe ikhono iwukudambisa izinsalela imfucuza sulfuric acid e amagesi isitshalo, kanye womshini ahlukahlukene udayi aniline iqembu (lisetshenziswa njengedivaysi photoresist - enamathela photosensitive). Esikhathini ukukhiqizwa iraba isicelo zokwenziwa sodium acetate esekelwe ikhono layo ukubambezela ngesikhathi iqine.

Endaweni yokudla, i-sodium acetate isetshenziswa njengoba uyalondoloza.

Technical sodium acetate kabanzi njengoba izithasiselo antimoroznoy ahlukahlukene kwenza Concretes asetshenziswa ekwakhiweni Monolithic izakhiwo zikakhonkolo, nokuziphatha neminye imisebenzi yokwakha ephathelene ne-ukubekwa uphawu kanye izakhiwo eqinisa ngaphansi kwamazinga okushisa aphansi. Lolu hlelo lokusebenza kungenxa ikhono ukuvimbela okokuqandisa ketshezi amamiksi ukhonkolo cishe zonke ngemijikelezo ubuchwepheshe ekwakheni - zokuthutha, izakhiwo ukulondolozwa, amatshe kanye nabanye. Ikakhulukazi, i-sodium acetate kunomthelela Izingxube settable ngaphansi kwamazinga okushisa aphansi, ngaphandle ukwehlisa izinga yabo futhi ngaphandle Okwenza lo Uhlelo lokulungiselela yabo. Ukusetshenziswa Its buthakathaka kakhulu insimbi ukwakhiwa ukuhlangana inqubo futhi ubangela amandla ngokhonkolo.

Isakazwe ukusetshenziswa sodium acetate e ekhemisi njengoba isakhi womshini isisu, kanye alkalinization umzimba e hyponatremia futhi lactic umzimba.

Thola ukuzi lezi zinto zingase, futhi ekhaya. Indlela yokwenza i-sodium acetate ekhaya? Kulula. Thatha 1 kg of soda abavamile futhi 1 ilitha uviniga. Khona-ke, kancane kakhulu, uhlanganise nabo esitsheni ingilazi, inqubo isazoqhubeka inqobo kuze encimfelwayo sithule. Une ezansi isitsha kuyoba Monolithic hydrated sodium acetate. Khona-ke kufanele ukufuthelana ancibilike ngokuphelele futhi asuse kwenze by filtration. Etholwe ifomu okumsulwa ingilazi oncibilikisiwe kufanele selehlile ekamelweni lokushisa ngaphambi kokusipakisha. Uthole ketshezi ewuketshezi, ukunikeza kuwukudlala okuqinile silula - kubalulekile kule crystal liquid ukwengeza nje kancane okufanayo sodium acetate. Ngakho, umuntu angabona ukuqhuba amaningi Overstore izinto, kuye ngokuthi yikuphi yayo isimo aggregate kuyadingeka.
