Acetic acetic: iipropati, nokulungiselela kunye nokusetyenziswa

Anhydrides ye asidi carboxylic - ayimveliso emzimbeni le iimolekyuli. Ezi luphawulwa radicals isomerism biosoedineny. Xa amagama anhydrides acid carboxylic ezininzi eziqhele ukusetyenziswa kwamagama nokuhlelwa zembali (umz, acetic, acetic acid, acetic maleic, njalo njalo). Ngexesha kongezwe asidi carboxylic dehydrating arhente (njenge phosphorus oxide) yenzeka emzimbeni zabo, kukhokelele kwinto yokuba kusekwe anhydrides acid carboxylic.

acetic acetic: Ukulungiswa

Umchiza Isihloko wafumana ukuba wahlamba ngeendlela ezininzi. Ezwi yayo ezininzi eziqhele ukusetyenziswa phosphorus oxide, nto leyo arhente kakhulu dehydrating. Kukwakho nezinye iindlela ngenxa Yindibanisela acetic. Ngokomzekelo, ngaba acetic acetic zingafunyanwa phantsi kwe sisenzo phosphate njengoko acid acetic acetate. Inkqubo okupholisa idityaniswe dropwise SN3SOS1 yamasuntswana nalinye isuntswana dewatered kwaye woma ngokupheleleyo asidi-sodium acetate. Lo mxube ngenxa eshushubeziwe ephakathi kwaye acetic acetic kuhlelwe isuswe ibhafu esantini uze emva koko nyulu ulwelo. Ngenxa yokusebenza eveliswa zinuka ngamandla ulwelo acetate acid.

acetic acetic, kunye nezinto ephantsi-ezinto - ulwelo kunye livumba elibukhali, phantse ezingenakunyibilika emanzini, lula enyibilikayo ezininzi izinto eziphilayo. Kufuneka kuqatshelwe ukuba anhydrides abafumana asidi carboxylic (ingakumbi ngokunciphisa) - eziqinileyo esha. iqondo lobushushu abilayo ngaphezulu kakhulu kunokuba ehambelana asidi carboxylic.

acetic acetic: Chemical Properties

Le compound iqhele ukusetyenziswa amalungu amaninzi kwiiklasi ezahlukeneyo nezinto eziphilayo ngeendlela organic yokuqaphela. Xa abasabela ngayo anhydrides ngamanzi ukunika iimolekyuli ezimbini acid ohambelana.

Amonoliz anhydrides kukhokelela ukuyilwa amides kunye neetyuwa ze ehambelana asidi carboxylic. Abasabela ngayo kusetyenziswa zokufumana alkoliza kunye anhydrides esters.

acetic Acetal lisetyenziswa dehydrating kunye nearhente acetylating kwinkqubo yemveliso atsetiltselyulozy, IVinyl acetate, amayeza, dimethylacetamide, colorants, izinto elimnandi, njl aldehyde acetate kuyacaphukisa ukuya iphecana yokuphefumla, amehlo, eyethisa isikhumba nokutsha.

Kwincindi acetate afunyenwe ngenxa yokuba isenzo kwi neselulosi acetate acetic phambi ngumnxibelelanisi (sulphate acid). acetylation ezingagqitywanga walungisa diacetates mono- neselulosi. Khe neselulosi triacetate ezisetyenziswa ukuvelisa isilika acetate. Ukulungiselela le njongo ke iqhawulwa ngomxube acetone kunye ethanol (85:15) okanye acetone ecocekileyo. isisombululo Viscous ifunyenwe leyo extruded ngokusebenzisa izihluzi ezizodwa. imicu Thin yezisombululo zome jikisa nebomvu, okusetyenziselwa ukuvelisa iintlobo ezahlukeneyo vulu imicu zokwenziwa.

Izicelo mveliso zisetyenziswa kunye nezinye anhydrides. acetic Maleic - into crystalline, kakuhle enyibilikayo emanzini kwaye acetone, linyibilike kwi 52,85 ° C. Ngokuqhelekileyo, le nto ilungisiwe ukususela maleic acid. Isetyenziswa ekuveliseni zinambuzane, ipholiyesta kunye nentlaka alkyd. acetic Phthalic iveliswa ngenxa igcwala of naphthalene. Le yokugqibela isetyenziselwa Yindibanisela Abakhuthazi ukukhula, amayeza okubulala izinambuzane, kwakunye amanye amayeza. acetic Phthalic - crystalline esiluqilima kunye indawo ukunyibilika 128 ° C. Uthe acetic isetyenziselwa ukufumana ਫ਼ੂਜਿੰਗ inkqubo (isibonisi kunye medicament). Le acetic isetyenziselwa Izigxothi nokuveliswa (dimethyl phthalate).
