I le tulaga o le kemisi faʻaletino, o le taua o le faʻaitiitia o mea e le mafai ona faʻateleina. Faatasi ai ma mea eseese o loʻo faʻaaogaina mo lenei faʻamoemoe, o le acetyl chloride e tu i fafo mo ona uiga faʻapitoa ma agavaʻa. O lenei blog o le a tuʻuina atu se vaʻaiga loloto i meatotino o le acetyl chloride, o ana faʻaoga, ma lana matafaioi i le faʻaitiitia o vaega faʻaogaina o meaola.
O le a le acetyl chloride?
Acetyl chloride, fua fa'ama'i CH3COCl, ose chloride acid e maua mai le acetic acid. O se vai e leai ni lanu ma se manogi manogi ma e maualuga lona gaioiga, aemaise lava ile vai ma le ava malosi. O lenei fa'agaoioiga e avea ai ma mea taua i le tele o gaioiga fa'a-kemikolo, ae maise i le tu'ufa'atasiga o isi mea fa'aola.
Le matafaioi a le acetyl chloride i le faʻaitiitia o tali
O se tasi o talosaga autu oacetyl chloridee fai ma sui fa'aitiitiga i kemisi fa'aola. E sili ona aoga i le faʻaitiitia o aldehydes, ketones ma chlorinated phthalides. O le mafai ona filifili fa'aitiitia nei vaega fa'atino e avea ai le acetyl chloride o se meafaigaluega taua mo foma'i.
Fa'aitiitia aldehydes ma ketones
Aldehydes (RCHO) ma ketones (RCOR) o vaega galue masani i faʻalapotopotoga faʻapitoa. O le fa'aitiitiga o nei vaega e taua tele mo le tu'ufa'atasiga o 'ava mālosi ma isi mea e maua mai.Acetyl chloridee mafai ona faafaigofieina lenei suiga e ala i le tuuina atu o electrons, faaliliu lelei le vaega carbonyl i se vaega hydroxyl. E le gata o lenei tali lelei, ae e mafai ona filifili faʻaititia vaega faʻapitoa e aunoa ma le aʻafiaina o isi vaega galue i le mole.
Naphthalene fa'a'oloina
Ophthalones chlorinated o se isi vasega o mea faʻapipiʻi e mafai ona faʻaititia i le faʻaaogaina o le acetyl chloride. E masani ona fa'aogaina nei mea fa'aoga i fa'ailoga pH ma vali. O le faʻaitiitiga faʻagasologa e mafai ona suia a latou meatotino, faʻafaigofie atili mo talosaga faʻapitoa. E ala i le faʻaaogaina o le acetyl chloride, e mafai e kemisi ona ausia suiga manaʻomia aʻo tausia le faʻamaoni o le fausaga atoa.
Tulaga lelei o le faʻaaogaina o le acetyl chloride
1. Filifiliga:O se tasi o faʻamanuiaga sili ona taua o le faʻaaogaina o le acetyl chloride e fai ma sui faʻaitiitia o lona filifilia. E mafai ona fa'atatau i vaega fa'atino fa'apitoa e aunoa ma le a'afiaina o isi vaega fa'atino, fa'ataga sa'o suiga o molela'au lavelave.
2. Lelei:Ole fua ole tali e aofia ai le acetyl chloride e masani lava ona maualuga, e mafua ai le vave o taimi faʻapipiʻi. O lenei tulaga lelei e sili ona aoga i mea tau alamanuia lea e taua tele ai le taimi ma le tau.
3. Fetuuna'i:Acetyl chloride e mafai ona faʻaaogaina i le tele o gaioiga e ese mai i le faʻaitiitia, e aofia ai le acylation ma le ester synthesis. O lenei fegalegaleaiga e avea ai ma mea taua i totonu o le pusa meafaigaluega a le kemisi oona.
Puipuiga saogalemu
E ui lavaacetyl chlorideose reagent mamana, e tatau ona taulimaina ma le faaeteete. E pala ma e mafai ona mafua ai mu tuga pe a pa'i i le pa'u po'o mata. E le gata i lea, e faʻasaʻolotoina le hydrochloric acid pe a faʻafefe i le vai, lea e ono lamatia. E taua tele fa'atonuga mo le saogalemu pe a galulue fa'atasi ma lenei vaega, e aofia ai le fa'aogaina o mea e puipui ai le tagata lava ia (PPE) ma le galue i se nofoaga e lelei le ea.
Acetyl chlorideose fa'afefiloi mata'ina ile vaega ole kemisi fa'aola, ae maise ole fa'aitiitiga mo aldehydes, ketones ma chlorinated phthalides. O lona filifilia, lelei, ma le agavaʻa ua avea ai ma punaoa taua mo tagata suʻesuʻe kemisi. Ae ui i lea, o le saogalemu e masani lava o le popolega muamua pe a tagofia ia mea malosi. A'o fa'aauauina su'esu'ega kemisi fa'alela'au ma fa'aoga, e mautinoa lava o le a fa'aauau pea ona faia e le acetyl chloride se sao taua i le tu'ufa'atasia ma suiga o mea fa'aola.
