Isobutane (I.C4H10)

Siffofin fasaha

Isobutane, wanda kuma aka sani da 2-methylpropane, wani abu ne na halitta tare da tsarin sunadarai na C4H10 da lambar CAS na 75-28-5. Gashi ne mara launi, ƙamshi mai ƙamshi mai ƙamshi a ƙarƙashin zafin jiki da matsin lamba. Yana da ƙarancin guba kuma ana iya ɗaukar shi azaman mai sauƙin numfashi. Maɓallin narkewa: -159.4 ° C, wurin tafasa: -11.73 ° C, ɗan narkewa cikin ruwa, mai narkewa a cikin ethanol, ether, da dai sauransu Mafi yawa suna cikin iskar gas, gas mai tacewa da fashewar gas, wanda aka samu ta hanyar rabuwa ta jiki, da sauransu, iya Hakanan ana samun sa ta isomerization na n-butane. Yana haifar da cakuda mai fashewa tare da iska, kuma iyakar fashewar shine 1.9% zuwa 8.4% (ƙarar). Yana iya ƙonewa da fashewa lokacin da aka fallasa shi ga tushen zafi da buɗaɗɗen harshen wuta. Yana haifar da tashin hankali a kan hulɗa da oxidants. Tumbinsa ya fi iska nauyi kuma yana iya yaduwa zuwa nesa mai nisa a wani wuri mafi ƙanƙanta, kuma zai kunna lokacin da ya ci karo da tushen wuta. An fi amfani da shi don samar da isooctane ta hanyar alkylation tare da isobutylene, wanda ake amfani da shi azaman mai inganta octane na mai; ta hanyar fashewa, zai iya samar da isobutylene da propylene; ana iya yin alkylated tare da n-butene da propylene don samar da gas ɗin alkylated; yana iya samar da barasa na methyl. Acrylic acid, acetone, methanol, da dai sauransu An yi amfani da shi a cikin isooctane, a matsayin mai inganta octane na gas, ana amfani dashi wajen samar da isobutylene, propylene, methacrylic acid, a matsayin mai sanyaya abinci, mai sanyaya ruwa, da dai sauransu. daidaitaccen gas da kuma shirye -shiryen daidaitaccen gas ɗin gauraye na musamman. Ajiye a cikin shagon mai sanyi, mai iska don iskar gas mai ƙonewa. Ka nisanci tushen wuta da zafi. Yawan zafin jiki na ajiya bai wuce 30 ° C ba. ya kamata a nisanta shi daga oxidizer, kada ku adana tare. Yi amfani da hasken wuta mai ba da fashewa da wuraren samun iska. An hana amfani da kayan aikin injiniya da kayan aikin da ke da sauƙin tartsatsi. Ya kamata a tanada wurin ajiya da kayan jiyya na gaggawa.

Aikace -aikacen:

1. Ana amfani da shi musamman don samar da isooctane ta isomerization tare da isobutylene azaman mai inganta lambar octane don mai. Ana iya yin fashewar daga isobutylene da propylene. Alkylation na n-butene tare da propylene zuwa alkylate fetur. Ana iya shirya methacrylic acid, acetone da methanol. Hakanan za'a iya amfani dashi azaman firiji.

2. Tsarkin tsarki isobutane galibi ana amfani dashi azaman iskar gas da kuma shirye -shiryen daidaitaccen cakuda.

3. Don kira na isooctane, a matsayin mai inganta lambar octane na gas don shirya isobutylene, propylene, methacrylic acid, wanda ake amfani da shi azaman mai sanyaya ruwa.
