Isingeniso

I-Acetaldehyde, eyaziwa nangokuthi i-acetaldehyde noma i-ethylaldehyde, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-acetaldehyde:

Ikhwalithi:

1. Iwuketshezi olungenambala olunephunga elimnandi neliphunga elimnandi.

2. Iyancibilika emanzini, etshwaleni nasezincibilikisini ze-ether, futhi ingashintshashintsha.

3. Ine-polarity ephakathi futhi ingasetshenziswa njengesixazululi esihle.

Sebenzisa:

1. Isetshenziswa kabanzi ekukhiqizeni izimboni.

2. Kuyinto ebalulekile yokusetshenziswa kokuhlanganiswa kwamanye ama-compounds.

3. Ingasetshenziselwa ukukhiqiza amakhemikhali afana ne-vinyl acetate ne-butyl acetate.

Indlela:

Kunezindlela eziningana zokwenza i-acetaldehyde, evame kakhulu ukukhiqizwa yi-catalytic oxidation ye-ethylene. Inqubo yenziwa kusetshenziswa ama-oxygen kanye nama-catalysts ensimbi (isb, i-cobalt, i-iridium).

Ulwazi Lokuphepha:

1. Kuyinto enobuthi, ecasula isikhumba, amehlo, umgudu wokuphefumula kanye nohlelo lokugaya ukudla.

2. Kubuye kube uketshezi oluvuthayo, olungabangela umlilo lapho uvezwa elangabini elivulekile noma izinga lokushisa eliphezulu.

3. Izinyathelo ezifanele zokuphepha kufanele zithathwe lapho kusetshenziswa i-acetaldehyde, njengokugqoka amagilavu okuzivikela, izibuko nezinsimbi zokuphefumula, kanye nokuqinisekisa ukuthi isebenza endaweni enomoya omuhle.

Okwedlule: 1-Nonanal(CAS#124-19-6)
