Mawu Oyamba
2,5-Dimethylthiophene ndi organic pawiri. Ndi madzi otsika kawopsedwe komanso osayaka omwe amakhala otumbululuka achikasu mpaka opanda mtundu potentha.
Ubwino:
2,5-Dimethylthiophene imakhala ndi kusungunuka kwabwino ndipo imasungunuka muzitsulo zosungunulira monga ma alcohols, ethers ndi chlorinated hydrocarbons. Ili ndi kununkhira kwamphamvu kwa thiomycin ndipo imakhala ndi fungo loyipa pang'ono mumlengalenga.
Gwiritsani ntchito:
Njira:
Njira yokonzekera yodziwika bwino ya 2,5-dimethylthiophene imapezeka ndi thiophene ndi methyl bromide.
Zambiri Zachitetezo:
2,5-dimethylthiophene ili ndi kawopsedwe kakang'ono, komabe ndikofunikira kulabadira ntchito yotetezeka. Kukhudzana pakhungu ndi maso kuyenera kupewedwa mukakumana, magolovesi oteteza, magalasi ayenera kuvala, komanso zida zodzitetezera ziyenera kugwiritsidwa ntchito kunja kwa labotale. Ikagwiritsidwa ntchito kapena kusungidwa, iyenera kusungidwa kutali ndi magwero amoto ndi okosijeni, ndipo mpweya wabwino uyenera kusamalidwa. Mukalowetsedwa kapena kupumira, pitani kuchipatala mwamsanga.
