Hordhac

Acetaldehyde, oo sidoo kale loo yaqaan acetaldehyde ama ethyldehyde, waa unug dabiici ah. Kuwa soo socdaa waa horudhac ku saabsan sifooyinka, isticmaalka, hababka diyaarinta iyo macluumaadka badbaadada acetaldehyde:

Tayada:

1. Waa dareere aan midab lahayn oo leh basbaas iyo ur xun.

2. Waxay ku milmi kartaa biyaha, khamriga iyo dareerayaasha etherka, waxayna noqon kartaa mid kacsan.

3. Waxay leedahay polarity dhexdhexaad ah waxaana loo isticmaali karaa sida dareere wanaagsan.

Isticmaal:

1. Waxaa si weyn loogu isticmaalaa wax soo saarka warshadaha.

2. Waa walxo ceeriin ah oo muhiim u ah isku dhafka xeryahooda kale.

3. Waxaa loo isticmaali karaa in lagu soo saaro kiimikooyin sida vinyl acetate iyo butyl acetate.

Habka:

Waxaa jira dhowr siyaabood oo loo diyaariyo acetaldehyde, tan ugu badan oo ah in lagu soo saaro oksaydhka catalytic ee ethylene. Habka waxaa lagu fuliyaa iyadoo la isticmaalayo ogsijiin iyo biraha birta (tusaale, cobalt, iridium).

Macluumaadka Badbaadada:

1. Waa maaddo sun ah, oo ka xanaajisa maqaarka, indhaha, hab-dhiska neefsiga iyo hab-dhiska dheefshiidka.

2. Sidoo kale waa dareere guban kara, kaas oo keeni kara dab marka uu la kulmo holac furan ama heerkul sare.

3. Tallaabooyin badbaado oo habboon waa in la qaadaa marka la isticmaalayo acetaldehyde, sida xidhashada galoofyada ilaalinta, muraayadaha iyo qalabka neefsashada, iyo hubinta inay ku shaqeyso jawi hawo fiican leh.
