Intangiriro

Diethanol.

 

Ibyiza: Acetal diethanol ni ibara ritagira ibara ryumuhondo wijimye hamwe numuvuduko muke wumuyaga. Irashobora gushonga mumazi, alcool, na ether yumuti kandi ni uruganda rufite umutekano mwiza.

 

Imikoreshereze: Acetal diethanol ifite solubilité nziza, plastike hamwe nubushuhe. Bikunze gukoreshwa nkibishishwa, amazi yo kwisiga hamwe namavuta.

 

Uburyo bwo kwitegura: acetal diethanol muri rusange itegurwa na epoxy compound cyclization reaction. Okiside ya Ethylene ikoreshwa na alcool kugirango ibone Ethyl alcool diethyl ether, hanyuma ikorwa na hydrolysis ya catalizike ya hydrolysis kugirango ibe acetal diethanol.

 

Amakuru yumutekano: Acetal diethanol ni uburozi buke, ariko biracyakenewe kwitondera ikoreshwa neza. Irinde guhura na okiside ikomeye, acide ikomeye na okiside kugirango wirinde imiti cyangwa impanuka ziteye akaga. Uturindantoki dukwiye kurinda, amadarubindi, hamwe na hejuru bigomba kwambara mugihe cyo gukoresha.
