Gabatarwa

2,3-dimethyl-2-butene (DMB) wani fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga yanayinsa, amfaninsa, hanyoyin masana'anta da bayanan aminci:

 

inganci:

Bayyanar: DMB ruwa ne mara launi.

Solubility: Yana da narkewa a yawancin kaushi na halitta kamar ethanol, ethers, da hydrocarbons.

Yawa: Yawansa yana kusan 0.68 g/cm³.

Guba: DMB ba shi da ɗanɗano mai guba, amma wuce gona da iri na iya haifar da haushin ido da haushin fata.

 

Amfani:

Haɗin sinadarai: DMB ana yawan amfani da shi a cikin haɗaɗɗun kwayoyin halitta azaman ƙarfi, tsaka-tsaki, ko mai kara kuzari.

Masana'antar Man Fetur: Hakanan ana amfani da DMB azaman sinadari mai mahimmanci na aikace-aikace a cikin tace man petroleum da hanyoyin sarrafa sinadarai.

 

Hanya:

DMB ana shirya shi ta alkylation na methylbenzene da propylene. Matakan ƙayyadaddun sun haɗa da amsa methylbenzene da propylene a madaidaicin zafin jiki da matsa lamba a gaban mai kara kuzari don samar da DMB.

 

Bayanin Tsaro:

A matsayin kaushi na halitta, DMB ba shi da ƙarfi. A lokacin amfani, wajibi ne don kula da samun iska mai kyau da kuma kauce wa wuce gona da iri.

Zai iya haifar da haushi lokacin da ake hulɗa da fata da idanu. Ya kamata a guji dogon lokaci, shakar numfashi, ko hadiyewa.

Lokacin adanawa da sarrafa DMB, halayen da ke da ƙarfi mai ƙarfi da acid mai ƙarfi yakamata a guji.

Idan aka yi hulɗa da wannan abu, nan da nan a wanke gurɓataccen yanki ko idanu da ruwa mai yawa kuma a nemi kulawar likita.
