Pentane. Njirimara ya bụ ndị a:

Ọ bụ miscible na ọtụtụ organic mgbaze ma ọ bụghị na mmiri.

 

Njirimara kemịkalụ: N-pentane bụ hydrocarbon aliphatic nke na-ere ọkụ ma nwee ebe ọkụ dị ala na ọnọdụ okpomọkụ akpaaka. Enwere ike ịgba ya ọkụ na ikuku iji mepụta carbon dioxide na mmiri. Ọdịdị ya dị mfe, na n-pentane na-emeghachi omume na ọtụtụ ogige organic.

 

A na-eji N-pentane eme ihe n'ọtụtụ ebe na nyocha kemịkalụ, nkwadebe nke ihe mgbaze na ngwakọta ihe mgbaze, yana bụkwa ihe dị mkpa akụrụngwa na ụlọ ọrụ mmanụ ala.

 

Usoro nkwadebe: n-pentane na-enweta nke ọma site n'ịgbawa na imezigharị na usoro nhazi mmanụ ala. Ngwa ahịa mmanụ ala nke usoro ndị a na-emepụta nwere n-pentane, nke nwere ike kewapụ ma mee ka ọ dị ọcha site na distillation iji nweta n-pentane dị ọcha.

 

Ozi nchekwa: n-pentane bụ mmiri ọkụ na-ere ọkụ na ekwesịrị ka edebe ya pụọ ​​na ọkụ mepere emepe na oke okpomọkụ. Ekwesịrị iji ya mee ihe na mpaghara ikuku nke ọma ma zere kọntaktị na ihe ndị na-emepụta ihe siri ike.
