Nhanganyaya

2,3-dimethyl-2-butene (DMB) is an organic compound. Inotevera sumo kune hunhu hwayo, kushandiswa, nzira dzekugadzira uye ruzivo rwekuchengetedza:

 

Hunhu:

Chitarisiko: DMB imvura isina ruvara.

Solubility: Inonyungudika muzvinonyungudutsa zvakawanda zvakaita se ethanol, ethers, nemahydrocarbons.

Density: Density yayo inenge 0.68 g/cm³.

Toxicity: DMB haina muchetura zvishoma, asi kuratidzwa zvakanyanya kunogona kukonzera kusvotwa kweziso uye kushatirwa kweganda.

 

Shandisa:

Chemical synthesis: DMB inowanzoshandiswa mune organic synthesis se solvent, yepakati, kana catalyst.

Indasitiri yePetroleum: DMB inoshandiswawo sekemikari yakakosha yekushandisa mujute petroleum kunatsa uye petrochemical maitiro.

 

Nzira:

DMB inogadzirwa zvakajairika nealkylation yemethylbenzene uye propylene. Matanho chaiwo anosanganisira kuita methylbenzene uye propylene pane tembiricha yakakodzera uye kudzvanywa pamberi peiyo catalyst yekugadzira DMB.

 

Zvekuchengetedza

Se organic solvent, DMB inoshanduka. Panguva yekushandiswa, zvinodikanwa kuchengetedza mhepo yakanaka uye kudzivirira kuratidzwa kwakanyanya.

Inogona kukonzera kushatirwa kana yasangana neganda nemaziso. Kusangana kwenguva refu, kufemerwa, kana kumedza kunofanira kudziviswa.

Pakuchengeta nekubata DMB, maitiro ane oxidants akasimba uye maasidhi akasimba anofanira kudzivirirwa.

Kana wasangana nechinhu ichi, pakarepo sukurudza nzvimbo yakasvibiswa yeganda kana maziso nemvura yakawanda uye tsvaga kurapwa.
