Acetal diethanol.

Ngwongwo: Acetal diethanol bụ mmiri mmiri na-acha odo odo na-enweghị ụcha nke nwere ike ikuku dị ala. Ọ na-agbaze na mmiri, alcohols, na ether solvents na ọ bụ ngwakọta nke nwere nkwụsi ike dị mma.

Na-eji: Acetal diethanol nwere ezigbo solubility, plasticity na wetting Njirimara. A na-ejikarị ya eme ihe dị ka ihe mgbaze, mmiri mmiri na mmanụ mmanu.

Usoro nkwadebe: acetal diethanol na-akwadokarị site na mmeghachi omume cyclization ngwakọta nke epoxy. Ethylene oxide na-emeghachi omume na mmanya na-aba n'anya iji nweta ethyl alcohol diethyl ether, bụ nke a na-emepụta site na acid-catalyzed hydrolysis iji mepụta acetal diethanol.

Ozi nchekwa: Acetal diethanol bụ ihe dị ala na-egbu egbu, ma ọ ka dị mkpa ịṅa ntị na iji nchekwa. Zere ịkpọtụrụ ndị oxidants siri ike, acid siri ike na oxidants iji gbochie mmeghachi omume kemịkal ma ọ bụ ihe mberede dị ize ndụ.
