Intshayelelo

I-acetaldehyde, eyaziwa ngokuba yi-acetaldehyde okanye i-ethylaldehyde, yi-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-acetaldehyde:

Umgangatho:

1. Lulwelo olungenambala oluneziqholo nevumba elirhabaxa.

2. Inyibilika emanzini, etywaleni nakwizinyibilikisi ze-ether, kwaye isenokuguquka.

3. Ine-polarity ephakathi kwaye ingasetyenziselwa njenge-solvent efanelekileyo.

Sebenzisa:

1. Isetyenziswa ngokubanzi kwimveliso yemizi-mveliso.

2. Yimpahla ebalulekileyo ekrwada yokwenziwa kwezinye iikhompawundi.

3. Ingasetyenziselwa ukuvelisa iikhemikhali ezifana ne-vinyl acetate kunye ne-butyl acetate.

Indlela:

Kukho iindlela ezininzi zokulungisa i-acetaldehyde, eyona ixhaphakileyo ukuba iveliswe yi-catalytic oxidation ye-ethylene. Inkqubo iqhutyelwa ngokusebenzisa i-oxygen kunye ne-catalysts yensimbi (umzekelo, i-cobalt, i-iridium).

Ulwazi ngoKhuseleko:

1. Yinto enetyhefu, ecaphukisa ulusu, amehlo, umgudu wokuphefumula kunye nenkqubo yokugaya.

2. Kwakhona lulwelo olunokutsha, olunokubangela umlilo xa ubonakaliswe kwidangatye elivulekileyo okanye ukushisa okuphezulu.

3. Kufuneka kuthathwe amanyathelo afanelekileyo okhuseleko xa usebenzisa i-acetaldehyde, njengokugqoka iiglavu zokukhusela, iiglasi kunye neziphefumlo, kunye nokuqinisekisa ukuba isebenza kwindawo enomoya.
