Selelekela

Acetaldehyde, eo hape e tsejoang e le acetaldehyde kapa ethylaldehyde, ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea acetaldehyde:

Boleng:

1. Ke mokelikeli o se nang 'mala o nang le monko o monate le o monate.

2. E qhibiliha ka metsing, joala le metsoako ea ether, 'me e ka fetoha lerata.

3. E na le polarity e mahareng 'me e ka sebelisoa e le solvent e ntle.

Sebelisa:

1. E sebelisoa haholo tlhahiso ea indasteri.

2. Ke thepa e tala ea bohlokoa bakeng sa ho kopanya metsoako e meng.

3. E ka sebelisoa ho hlahisa lik'hemik'hale tse kang vinyl acetate le butyl acetate.

Mokhoa:

Ho na le mekhoa e mengata ea ho lokisa acetaldehyde, eo hangata e hlahisoang ke catalytic oxidation ea ethylene. Ts'ebetso e etsoa ho sebelisoa li-catalysts tsa oksijene le tšepe (mohlala, cobalt, iridium).

Lintlha tsa Tšireletseho:

1. Ke ntho e chefo, e halefisang letlalo, mahlo, mokhoa oa ho hema le tsamaiso ea lijo.

2. Hape ke mokelikeli o tukang, o ka bakang mollo ha o pepesehetse lelakabe le bulehileng kapa mocheso o phahameng.

3. Mehato e nepahetseng ea tšireletso e lokela ho nkoa ha u sebelisa acetaldehyde, e kang ho roala li-gloves tse sireletsang, likhalase le li-respirators, le ho etsa bonnete ba hore e sebetsa sebakeng se nang le moea o motle.
