Yavaibvisa acetate

A fuma ane mushonga payakavakirwa iri - CH3COONa - ndiye yavaibvisa munyu acetic asidhi kana yavaibvisa acetate. Chinonziwo vakanyorwa yemarudzi mazita zvokuwedzera zvokudya pasi chikamu nhamba iri E-262.

The fuma iri sekristaro, noruvara ruvara izvo uve zvinobva akacheneruka yero pakadzika mashava. The epamba ezvinhu rinoshandiswawo nezita yavaibvisa acetate. The fuma yavaibvisa acetate - nonflammable, kuchengeteka kupatsanura basa mugwaro rechina. Yavaibvisa acetate kuputika-uchapupu uye ane yakaderera toxicity, zviri munzira dzakawanda nokuda wayo kwazvo kushandisa iri maindasitiri kugadzirwa uye upenyu hwezuva nezuva.

Zvinonzi yaunganidzwa maitiro pamwe NaOH kana Na2CO3 acetic asidhi kana esters kuti asidhi iyi. Yakabudiswa fuma, kazhinji yakasimba. Mugore maindasitiri kweShanduro vakawanda chikamu munyu iri anhydrous wehurumende yakaiswa kuti kazhinji haana asingasviki 50%. Kushanda zvinoda fuma pasi zvimwe zvinhu, semuenzaniso, tembiricha nemiganhu abvume (ambient tembiricha haafaniri kupfuudza 5 madhigirii).

Makemikari indasitiri Kazhinji zvakakosha kuti neutralize kungatikanganisa zvinhu uye yeimwe. Mumwe zvinhu yakadaro sulfuric acid. Kuti neutralize nayo, uye yavaibvisa acetate rinoshandiswa kuisa sulfuric asidhi iri neutralized kuumbika oksosoli Na2SO4, zvinhu akadonhedza panguva neutralization maitiro kuumba chena precipitate. Izvi Maitiro kutyisidzira kudzivisa chepfu uye anopisira kuna leakage kuna sulfuric acid.

Sezvatotaurwa, nefuma zvinowanzodavirwa kushandiswa muminda siyana. Muna Whitehead Textile indasitiri chishandisei chete inobva kukwanisa neutralize vakasara tsvina sulfuric asidhi iri chirimwa choutsi, uyewo kugadzirwa-siyana madhayi aniline boka (kushandiswa senzira photoresist - photosensitive unhani). In pagadzirwe chakaita zvokugadzirwa rabha kushandiswa yavaibvisa acetate kwakavakirwa kukwanisa wayo zvishoma panguva vulcanization.

Yaigadzira zvokudya, yavaibvisa acetate rinoshandiswa senzira zvisaora.

Technical yavaibvisa acetate unoshandiswa nevakawanda sezvo yokuvirisa kuti siyana antimoroznoy kunoita concretes zvinoshandiswa kuvaka monolithic kongiri zvivako, uye kuitisa vamwe kuvaka akavhiyiwa chokuita chisimbiso uye kusimbisa hurongwa yakaderera tembiricha. Chikumbiro ichi imhaka kukwanisa kudzivisa nechando ari pafuma nekongiri mixes mune zvinenge zvichiitika zvose unyanzvi hwokuvaka - chokufambisa, zvivako Kuchengetedzwa, masonry uye nevamwe. Zvikurukuru, yavaibvisa acetate zvinobatsira settable wemisanganiswa yakaderera tembiricha pasina richikwidibira unhu hwavo uye pasina complicating mutoo kuti gadziriro yavo. Kushandiswa kwaro simba kungatikanganisa kuvakwa kuungana kwacho zvikuru uye zvinoita kuti simba nekongiri.

Anoparadzirwa nokushandisa yavaibvisa acetate mune chemishonga sechinhu chezvinonhuwira kuti zvaAtemisi diuretics, uyewo alkalinization of Muviri iri hyponatremia uye metabolic acidosis.

Wana anogona zvinhu izvi, uye musha. How kuti yavaibvisa acetate kumba? Zviri nyore. Tora 1 kg zvavo pasoda uye 1 fő nevhiniga. Zvadaro, zvishoma nezvishoma, sanganisa navo regirazi mugaba, muitiro kuchapfuurira kusvikira kusvikira muridzo rinomira. Une pazasi ngarava richava monolithic hydrated yavaibvisa acetate. Ipapo anofanira neshungu kuti chose kunyunguduka kubvisa precipitate kubudikidza filtration. Vakawana yakachena chimiro yakaumbwa girazi anofanira dzaserera mumba tembiricha vasati kavha. Makagamuchira nefuma iri mvura, kuti ape yakasimba chimiro yakareruka - zvakafanira muna mvura sekristaro chete kuwedzera zvishoma zvakafanana yavaibvisa acetate. Saka, munhu anogona kuitisa kakawanda Overstore zvinhu, zvichienderana izvo waro uwandu hwezvinhu zvose zvabatanidzwa. mamiriro kunokosha.
