Intangiriro

Acetaldehyde, izwi kandi nka acetaldehyde cyangwa Ethylaldehyde, ni ifumbire mvaruganda. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya acetaldehyde:

Ubwiza:

1.Ni amazi atagira ibara afite impumuro nziza kandi nziza.

2. Irashobora gushonga mumazi, inzoga hamwe na ether yumuti, kandi irashobora guhinduka.

3. Ifite polarite yo hagati kandi irashobora gukoreshwa nkumuti mwiza.

Koresha:

1. Ikoreshwa cyane mubikorwa byinganda.

2.Ni ibikoresho byingenzi byibanze byo guhuza ibindi bintu.

3. Irashobora gukoreshwa mugukora imiti nka vinyl acetate na butyl acetate.

Uburyo:

Hariho uburyo bwinshi bwo gutegura acetaldehyde, mubisanzwe muribyo bigomba gukorwa na okiside ya catalitike ya Ethylene. Inzira ikorwa hifashishijwe ogisijeni na catalizator (urugero, cobalt, iridium).

Amakuru yumutekano:

1.Ni ibintu byuburozi, bikarakaza uruhu, amaso, inzira zubuhumekero hamwe na sisitemu yumubiri.

2. Nayo mazi yaka umuriro, ashobora gutera umuriro mugihe uhuye numuriro ufunguye cyangwa ubushyuhe bwinshi.

3. Hagomba gufatwa ingamba zikwiye z'umutekano mugihe ukoresheje acetaldehyde, nko kwambara uturindantoki turinda, ibirahuri hamwe nubuhumekero, no kureba ko ikorera ahantu hafite umwuka mwiza.

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