4,5-Dimethylthiazole jẹ ẹya Organic yellow. Eyi ni diẹ ninu awọn ohun-ini rẹ, awọn lilo, awọn ọna iṣelọpọ, ati alaye ailewu:
Didara:
- Irisi: Omi ti ko ni awọ tabi okuta to lagbara.
- Solubility: Soluble ni ọpọlọpọ awọn olomi Organic gẹgẹbi awọn ọti, ethers ati awọn ketones.
- Iduroṣinṣin: O jẹ iduroṣinṣin ni iwọn otutu yara.
Lo:
- O tun le ṣee lo bi ohun imuyara roba ati oluranlowo vulcanizing roba lati mu ilọsiwaju awọn ohun-ini ẹrọ ti roba.
Ọna:
- 4,5-Dimethylthiazole le jẹ iṣelọpọ nipasẹ iṣesi ti dimethyl sodium dithiolate ati 2-bromoacetone.
- Idogba esi: 2-bromoacetone + dimethyl dithiolate → 4,5-dimethylthiazole + sodium bromide.
