Diisopropyl ether

Kayayyakin sinadarai:

Ruwa mara launi, mai ruwa, mai kama da wuta, mai matsakaicin canzawa, tare da ƙamshi na musamman na ether. Yana iya samar da azeotrope tare da ruwa, isopropyl alcohol, acetone, acetonitrile da ethanol.

Manufa:

Diisopropyl ether kyakkyawan maganin narkewa ne ga mai na dabbobi, kayan lambu da ma'adanai da mai. Ana iya amfani da shi don cire nicotine daga taba. Hakanan kyakkyawan maganin narkewa ne ga kakin paraffin da resin. A masana'antu, ana haɗa diisopropyl ether da sauran abubuwan narkewa don shafawa ga samfuran da ke tushen paraffin. Tsarin cire mai. A matsayin mai narkewa, ana amfani da shi a cikin magunguna, sinadarai marasa hayaki, shafa fenti da tsaftace fenti. Diisopropyl ether yana da yawan adadin octane da kaddarorin hana daskarewa kuma ana iya amfani da shi azaman wakilin haɗa mai. Wannan samfurin yana samar da peroxide cikin sauƙi kuma yana fashewa lokacin da aka girgiza. Sau da yawa ana ƙara para-benzylaminophenol azaman mai daidaita. Tasirin maganin sa barci na diisopropyl ether ya fi na diethyl ether sauƙi, amma tsawon lokacin maganin sa barci ya fi tsayi.

Hanyar samarwa A fannin masana'antu, ana iya samunsa daga sinadarin isopropyl barasa da aka samar daga sinadarin propylene sulfuric acid. Propylene yana amsawa da sinadarin sulfuric acid don samar da isopropyl hydrosulfate, wanda daga nan sai a mayar da shi zuwa isopropyl barasa. A lokacin amsawar, isopropyl hydrogen sulfate da propylene suna ci gaba da amsawa ga samuwar diisopropyl sulfate, wanda ke amsawa da isopropyl barasa don samar da isopropyl hydrogen sulfate da diisopropyl ether. Bayan amsawar sinadarin sulfuric acid, ana cire kayan Chemicalbook da tururi a cikin hasumiyar desorption don fitar da isopropyl barasa da diisopropyl ether daga maganin acid. Sannan, ta hanyar distillation, ana fara samun diisopropyl ether daga saman hasumiyar. A dakin gwaje-gwaje, ana iya samun isopropyl ether ta hanyar fitar da sinadarin isopropyl barasa da sulfuric acid, ko kuma ta hanyar hydrogenating isopropyl barasa da acetone. Haka kuma ana iya samar da shi ta hanyar hada sinadarin isopropyl barasa da propylene. Haka kuma ana iya samar da Diisopropyl ether ta hanyar amfani da ion exchange resin.
