Diisopropyl ether

Njirimara kemịkalụ:

Mmiri mmiri na-enweghị agba, mmiri mmiri na-ere ọkụ nke nwere mgbanwe dị mfe, yana isi ether pụrụ iche. Ọ nwere ike ịmepụta azeotrope na mmiri, isopropyl alcohol, acetone, acetonitrile na ethanol.

Ebumnuche:

Diisopropyl ether bụ ezigbo ihe mgbaze maka mmanụ anụmanụ, akwụkwọ nri na mineral na abụba. Enwere ike iji ya wepụta nicotine na ụtaba. Ọ bụkwa ezigbo ihe mgbaze maka wax paraffin na resin. N'ụlọ ọrụ mmepụta ihe, a na-agwakọta diisopropyl ether na ihe mgbaze ndị ọzọ iji tinye na ngwaahịa ndị dabere na paraffin. Usoro mwepụ mmanụ. Dịka ihe mgbaze, a na-ejikwa ya na ọgwụ, kemịkalụ na-anaghị anwụrụ ọkụ, mkpuchi na nhicha agba. Diisopropyl ether nwere ọnụọgụ octane dị elu na ihe mgbochi oyi ma enwere ike iji ya dị ka ihe na-agwakọta mmanụ ụgbọala. Ngwaahịa a na-emepụta peroxide ngwa ngwa ma gbawaa mgbe a manyere ya. A na-agbakwụnyekarị para-benzylaminophenol dị ka ihe na-eme ka ọ kwụsie ike. Mmetụta anestetiiki nke diisopropyl ether dị mfe karịa nke diethyl ether, mana oge anestetiiki dị ogologo.

Usoro mmepụta N'ụlọ ọrụ mmepụta ihe, enwere ike ịchọta ya site na ihe si na mmanya isopropyl pụta site na mmiri ọgwụ propylene sulfuric acid. Propylene na-emeghachi omume na sulfuric acid iji mepụta isopropyl hydrosulfate, nke a na-emezi hydrolyzes ka ọ bụrụ isopropyl alcohol. N'oge mmeghachi omume ahụ, isopropyl hydrogen sulfate na propylene na-aga n'ihu na-emeghachi omume na-etolite diisopropyl sulfate, nke na-emeghachi omume na isopropyl alcohol iji mepụta isopropyl hydrogen sulfate na diisopropyl ether. Mgbe mmeghachi omume hydration sulfuric acid gasịrị, a na-ewepụ ihe Chemicalbook na steam n'ime ụlọ elu desorption iji wepụta isopropyl alcohol na diisopropyl ether site na ngwọta acid. Mgbe ahụ, site na distillation, a na-ebu ụzọ nweta diisopropyl ether site n'elu ụlọ elu ahụ. N'ime ụlọ nyocha, enwere ike nweta isopropyl ether site na iwepụ mmiri ọgwụ isopropyl na sulfuric acid, ma ọ bụ site na hydrogenating isopropyl alcohol na acetone. Enwere ike ịmepụta ya site na catalytic condensation nke isopropyl alcohol na propylene. Enwere ike ịmepụta Diisopropyl ether site na usoro resin mgbanwe ion.
