Isobutane (I.C4H10)

Nka nka

Isobutane, nke a makwaara dị ka 2-methylpropane, bụ ihe ọkụkụ nwere usoro kemịkalụ nke C4H10 yana nọmba CAS nke 75-28-5. Ọ bụ gas na -enweghị ụcha, na -esi ísì ọkụ n'okpuru ọnọdụ okpomọkụ na nrụgide nkịtị. O nwere obere nsí, a pụkwara iwere ya dị ka ihe na -eku ume ọkụ. Ebe na -agbaze: -159.4 Celsius C, ebe esi esi: -11.73 ° C, ntakịrị mmiri nwere mmiri, soluble na ethanol, ether, wdg Nke kachasị dị na gas sitere n'okike, gas refinery na gas gbawara agbawa, nke enwetara site na nkewa anụ ahụ, wdg, nwere ike enwetakwa ya site na isomerization nke n-butane. Ọ na -emepụta ngwakọta mgbawa na ikuku, oke mgbawa bụ 1.9% ruo 8.4% (olu). Ọ nwere ike gbaa ma gbawaa mgbe ekpughere ya na isi ọkụ na ọkụ na -emeghe. Ọ na -emeghachi omume ike na kọntaktị na oxidants. Alụlụụ ya dị arọ karịa ikuku ma nwee ike gbasaa ruo ebe dị anya n'ebe dị ala, ọ ga -amụnye ọkụ mgbe ọ hụrụ ebe ọkụ na -agba. A na -ejikarị ya emepụta isooctane site na alkylation na isobutylene, nke a na -eji dị ka mmanụ ọkụ octane na -eme mmanụ ọkụ; site na mgbawa, ọ nwere ike mepụta isobutylene na propylene; enwere ike inye ya n-butene na propylene iji mepụta mmanụ alkylated; ọ nwere ike mepụta mmanya methyl. Acrylic acid, acetone, methanol, wdg Eji ya mee ihe na isooctane, dị ka mmanụ ọkụ octane improver, ejiri mee ihe isobutylene, propylene, methacrylic acid, dị ka friji, friji, wdg. ọkọlọtọ gas na nkwadebe gas pụrụ iche agwakọtara. Chekwaa n'ụlọ nkwakọba ihe dị jụụ, nke nwere ikuku maka gas na -ere ọkụ. Wepụ ọkụ na isi mmalite ọkụ. Ọnọdụ okpomọkụ ekwesịghị ịdị elu karịa 30 Celsius. ekwesịrị idobe ya site na oxidizer, echekwala ọnụ. Jiri ọkụ na-egbochi mgbawa na ụlọ ikuku. Amachibidoro iji ngwa ọrụ na ngwaọrụ ndị na -adịkarị ọkụ. Ekwesịrị ịkwado ebe nchekwa ihe nwere ngwa mgbapụta ihe mberede.

Ngwa:

1. A na -ejikarị ya maka mmepụta isooctane site na isomerization na isobutylene dị ka ọnụọgụ octane na -adịghị mma maka mmanụ ụgbọ ala. Enwere ike ime mgbawa ahụ site na isobutylene na propylene. Ntughari nke n-butene nwere propylene na mmanụ alkylate. Enwere ike ịkwadebe Methacrylic acid, acetone na methanol. Enwekwara ike iji ya dị ka friji.

2. Ịdị ọcha dị elu A na -ejikarị isobutane dị ka gas ọkọlọtọ na nkwadebe ngwakọta ọkọlọtọ pụrụ iche.

3. Maka njikọ nke isooctane, dị ka onye na -eme ka ọnụọgụ octane gasoline dị maka nkwadebe nke isobutylene, propylene, methacrylic acid, nke ejiri dị ka friji.
