Nhanganyaya
4,5-Dimethylthiazole ndeye organic compound. Heano zvimwe zvezvivakwa zvayo, kushandiswa, nzira dzekugadzira, uye ruzivo rwekuchengetedza:
Hunhu:
-Kutaridzika: Mvura isina ruvara kana crystalline yakasimba.
- Solubility: Inonyungudika mune zvakawanda organic zvinonyungudutsa senge madoro, ethers uye ketoni.
- Kugadzikana: Yakagadzikana pane tembiricha yekamuri.
Shandisa:
-Inogona zvakare kushandiswa seyerubha accelerator uye rubber vulcanizing agent kuti uvandudze michina yerubha.
Nzira:
- 4,5-Dimethylthiazole inogona kubudiswa nekuita kwe dimethyl sodium dithiolate uye 2-bromoacetone.
- Reaction equation: 2-bromoacetone + dimethyl dithiolate → 4,5-dimethylthiazole + sodium bromide.
Zvekuchengetedza
- 4,5-Dimethylthiazole ndeye organic compound uye inofanira kudziviswa nematanho akakodzera ekubata.
-Magurovhosi ekudzivirira, gogi uye gown zvinodikanwa panguva yekushandiswa.
- Dzivisa kufemesa mhute dzayo uye simbisa kushanda munzvimbo ine mhepo inofefetera.
- Kana ukangoputika netsaona mumaziso, sukurudza nekukasira nemvura yakawanda uye tsvaga kurapwa nekukasika.
- Chengetedza 4,5-dimethylthiazole munzvimbo inotonhorera, yakaoma kure neoxidants uye yakasimba acids.
