Mawu Oyamba

4-Methyl-5-vinylthiazole ndi organic pawiri,

 

Maonekedwe a 4-methyl-5-vinylthiazole amaphatikiza madzi opanda mtundu okhala ndi fungo lapadera la thiol. Imasungunuka mu zosungunulira za organic monga ethanol ndi etha komanso osasungunuka m'madzi.

Amagwiritsidwanso ntchito popanga chothandizira ndi zinthu za polima.

 

Kukonzekera kwa 4-methyl-5-vinylthiazole kumaphatikizapo vinyl thiazole, yomwe imachitidwa ndi methyl sulfide kuti ipeze mankhwala omwe akufuna. Njira yeniyeni yokonzekera ikhoza kusankhidwa malinga ndi zosowa ndi chiyero chofunikira.

Zitha kukhala zokwiyitsa komanso zowononga m'maso ndi pakhungu, ndipo magalasi oteteza ndi magolovesi ayenera kuvala panthawi yogwira ntchito. Zimakhalanso zoyaka ndipo ziyenera kupeŵedwa kuchokera ku kutentha kwakukulu ndi magwero oyaka.
